Hydrogen is an excellent energy source for long-term storage and free of greenhouse gases. However, its high production cost remains an obstacle to its advancement. The two main parameters contributing to the high cost include the cost of electricity and the cost of initial financial investment. It is possible to reduce the latter by the optimization of system design and operation conditions, allowing the reduction of the cell voltage. Because the CAPEX (initial cost divided by total hydrogen production of the electrolyzer) decreases according to current density but the OPEX (operating cost depending on the cell voltage) increases depending on the current density, there exists an optimal current density. In this paper, a genetic algorithm has been developed to find the optimal evolution parameters and to determine an optimum electrolyzer design. The optimal current density has been increased by 10% and the hydrogen cost has been decreased by 1%.

Hydrogen storage is a promising technology for storage of renewable energy resources. Despite its high energy density potential, the development of hydrogen storage has been impeded, mainly due to its significant cost. Although its cost is governed mainly by electrical energy expense, especially for hydrogen produced with alkaline water electrolysis, it is also driven by the value of the cell tension. The most common means of electrolyzer improvement is the use of an electrocatalyst, which reduces the energy required for electrochemical reaction to take place. Another efficient means of electrolyzer improvement is to use the Computational Fluid Dynamics (CFD)-assisted design that allows the comprehension of the phenomena occurring in the electrolyzer and also the improvement in the electrolyzer’s efficiency. The designed two-phase hydrodynamics model of this study has been compared with the experimental results of velocity profiles measured using Laser Doppler Velocimetry (LDV) method. The simulated results were in good agreement with the experimental data in the literature. Under the good fit with experimental values, it is efficient to introduce a new physical bubble transfer phenomenon description called “bubble diffusion”.

Owing to the progressive abandoning of the fossil fuels and the increase of atmospheric CO2 concentration, the use of renewable energies is strongly encouraged. The hydrogen economy provides a very interesting scenario. In fact, hydrogen is a valuable energy carrier and can act as a storage medium as well to balance the discontinuity of the renewable sources. In order to exploit the potential of hydrogen it must be made available in adequate quantities and at an affordable price. Both goals can be potentially achieved through the electrochemical water splitting, which is an environmentally friendly process as well as the electrons and water are the only reagents. However, these devices still require a lot of research to reduce costs and increase efficiency. An approach to improve their performance is based on nanostructured electrodes characterized by high electrocatalytic activity. In this work, we show that by using template electrosynthesis it is possible to fabricate Ni nanowires featuring a very high surface area. In particular, we found that water-alkaline electrolyzers with Ni nanowires electrodes covered by different electrocatalyst have good and stable performance at room temperature as well. Besides, the results concern nickel-cobalt nanowires electrodes for both hydrogen and oxygen evolution reaction will be presented and discussed. Finally, preliminary tests concerning the use of Ni foam differently functionalized will be shown. For each electrode, electrochemical and electrocatalytic tests aimed to establishing the performance of the electrolyzers were carried out. Long term amperostatic test carried out in aqueous solution of KOH will be reported as well.

Better understanding the properties of organic aerosols (OA) is attracting increasing attention because of the important role they play in climate change. The viscosity of OA has been shown to range from liquid to solid/semi-solid across the range of atmospheric relative humidity. A method known as the “bead-mobility technique” has been developed by Renbaum-Wolff et al. (Renbaum-Wolff, Grayson and Bertram 2013) to quantify the viscosity of an atmospheric particle over a range of atmospherically relevant humidities. The method is based on the assumption that the strength of the flow recirculation inside a droplet placed in a shear flow is related to the droplet viscosity. This paper presents a simple analytical model which predicts the internal flow in the droplet and provides a correlation relating the strength of the flow in the droplet to its viscosity. The validity of this analytical model is assessed by comparing the analytical results with a corresponding two-phase flow simulation with a moving mesh which captures the motion of the interface. The ability of the analytical model to reproduce experimental data reported in (Renbaum-Wolff, Grayson and Bertram 2013) is also quantified. The reasonable agreement between the analytical model and the experimental data confirms that the droplet velocity provides a useful proxy to estimate the droplet viscosity for small liquid samples for which standard viscometry techniques do not apply.

This article presents an exhaustive review of the transport properties necessary for the multiphysics modelling of alkaline water electrolyzer. This article provides experimental data and the correlations needed to calculate thermos-physical properties such as electrical conductivity, density, viscosity, heat capacity, heat and mass transfer diffusion coefficients as a function of temperature and electrolyte mass fraction for two classical alkaline electrolytes (KOH, NaOH). Thus, the different boundary layers growing on the electrodes can be calculated with precision. Different interpolation models from various authors are compared to raw experimental data. The goal of this article is to give to the modeler the correlations needed for the simulation of alkaline water electrolysis.

This paper investigates how and under which conditions the lamella of an impacting droplet is punctured by the presence of a small occlusion. Better understanding the conditions which lead to the rupture of the lamella is critical to produce defect free coating layers in the context of spray coating, for example. An analytical model based on surface energy analysis is proposed to obtain the critical thickness below which the liquid layer above the occlusion is unstable and lamella rupture occurs. Furthermore, we have developed a three dimensional multiphase lattice Boltzmann code to confirm the surface energy analysis and study the influence of key parameters like size of the occlusion, impact velocity and wettability of substrate on hole formation. Results show that a hole is more likely to appear as the diameter of the occlusion, the impact velocity, and the hydrophobicity of the surface increase.

In present study, we used activated carbon as an adsorbent for the removal of phenol from aqueous solution under various operating conditions. Statistical design using MATLAB® tools was employed to study the effects of three variables on six different response factors. MATLAB® software was employed to solve proposed quadratic model equations and to fitting a quadratic response surface. All the models with a very high adjusted R‐square predicted the experimental data well. The Thomas, the Yoon‐Nelson, the Wolborska, the bed depth service time and the linear driving force models were used to predict breakthrough curve for experimental data. Results showed that linear driving force model (LDFQ) was found suitable for the prediction of the breakthrough curve data.

Chemical enhanced oil recovery (EOR) is a successful method for increasing crude oil recovery. However, chemicals commonly used for enhanced oil recovery operations possess adverse biological impacts. To meet the legislative requirement and environmental protection demands, the performance of a highly biodegradable nonionic surfactant derived from tannic acid, a possible alternative, was evaluated using a microfluidic technology for the replacement of chemically synthesis surfactant by green chemistry products. Aqueous microdroplets containing the surfactant in crude oils were used for measurements of interfacial tension (IFT) reduction. The degree of interfacial tension reduction by sodium dodecyl sulfate (SDS), one of the most popular conventional surfactants, was also quantified for performance comparison. The potential of the biosurfactant for IFT reduction of light crude oil was superior to that of SDS. To evaluate the feasibility of the biosurfactant in improvement of recovery efficiency, surfactant-assisted flooding was tested under a random microfluidic network at the optimal concentrations, and the results were in good agreement with IFT reduction tests. The utilization of the polymer in a biosurfactant synthesis process effectively enhanced high sweep efficiency by decreasing a viscous fingering effect. The biosurfactant proved to be adequate and can sufficiently alleviate environmental concerns adopted by chemical flooding EOR.

Battery ageing and performance evolution prediction is one of the energy management key. The use of lead acid batteries is always strong despite its weight and the constant increasing, of new battery materials and technologies. The lead acid batteries are mainly used to start car engine or as primary energy source for forklift or pallet trucks. Another application is the storage of electrical energy produces by intermittent energy sources like photovoltaic, wind or tidal powers. Multiple factors influence lead acid batteries ageing depending of the type of batteries technology (vented or opened and VRLAB or sealed) and the kind of use. We focus our experimental study on four of them: the number of ageing cycles, the operating current, the use of electrolyte additives, containing EDTA and the temperature. Factors are investigated on two levels. The porosity sensitivity is mainly presented in the present work.

Recent advancements in microelectromechanical systems (MEMS) have required state-of-the-art techniques that provide accurate information of physical parameters such as fluid velocities and temperatures, at small scales, to fully characterize fluid flows in these devices. Especially it is difficult to measure temperature fields at microscale using conventional methods due to the limitation of spatial resolution in these techniques. In this paper, we present a comprehensive review of various advanced microscale thermometry techniques for measurements of bulk fluid or wall surface temperature fields. Differing from earlier publications, this review particularly focuses on categorizing the thermometry techniques based on how they measure temperature information at the microscale, i.e., either contact or noncontact methods. The paper presents details of measurement principles for each thermometry technique and includes a broad range of their applications. For the contact-based thermometry, the most recent fabrication and measurement results with micro-thermocouples are introduced, followed by discussions for scanning temperature probes and atomic force microscope (AFM) temperature probes. On the other hand, noncontact-based thermometry techniques are broadly summarized, including optical thermometry, liquid crystal thermometry, infrared thermometry, and Raman spectroscopy. Strengths and weaknesses of each technique compared to other approaches, with information of spatial, temporal, and temperature resolutions are introduced and discussed. This review will provide a general guideline for readers regarding the advantages and disadvantages of the most recent microscale thermometry techniques considering key requirements such as tool availability, system limitations, and temperature resolution.

During two-phase electrolysis processes, for example for hydrogen production, there are bubbles which are created at electrodes. This implies a great vertical motion source in the normal earth gravity field and then a quite important natural two-phase convection. All other fields are then affected. Heat, mass and electricity transfers are modified due to both bubbles screening (at surface and in volume) and to bubbles transport promotion. Many numerical modeling for two-phase processes such as kerosene pulverization in engines or coal combustion sciences have shown the difficulties of these multi-physics processes. Both particles and reactor scales must be considered according with a strong coupling modeling. In these processes the particles injection is "in the flow". In boiling or electrolysis processes, a new difficulty is added: particles birth or injection is strongly coupled to the local flow properties and leads to a complex boundary condition at surfaces. Electrical and electrochemical properties and processes are disturbed. This disturbance can lead to the modification of the local current density and to anode effects for example. The both experimental and numerical investigation is here presented. Experiments are performed in laboratory and in zero gravity (CNES grant and parabolic flights opportunities).

During two-phase electrolysis, bubble production occurs at one or two electrodes. This yields a large change for the electrolyser electrical and hydrodynamic properties. Under normal Earth gravity, the bubble production at the electrodes induces a macro-convection in the electrolyser. This leads to a modified local current density distribution at the electrodes. When gravity is avoided, bubbles are no longer subject to buoyancy forces and to the induced natural flow friction forces. Electrolysis was performed using a potentiostat, and gas bubble evolution was observed with cameras. Quantitative evolution laws for the electrochemical cell voltage, bubble diameter and population during two-phase electrolysis are established in function of the current density and gravity variation.

A gas diffusion electrode (GDE) consisting of a gas diffusion layer and a reaction layer was prepared. The gas diffusion layer was made of carbon (Vulcan XC500 or KS44), and PTFE as the binder. The reaction layer was composed of Ag powder as the catalyst, Vulcan XC500 or KS44 as the supported materials, and PTFE as the binder on a carbon cloth. Carbon supplies the channels and the reaction sites in the cathode. Scanning electron microscopy (SEM) observations and impedance spectroscopy were used to characterize the structure of the electrodes. The impedance measurements were carried out in order to clarify the double-layer capacitance. The oxygen reduction reaction (ORR) of the cathode was determined by the polarization curves of the half-cell in 4 M KOH electrolyte with a dry air supply. The carbon size was found to have a significant impact on the electrode intra-structure which is related to the reaction sites. The use of Vulcan XC500 GDE had a higher ORR performance than that of KS44. The addition of milled KS44 to the GDE resulted in achieving a better ORR performance.

International audienceDuring two-phase electrolysis for hydrogen production, according with alkaline-water electrolysis process, there are bubbles which are created at electrodes which imply a great hydrodynamic acceleration in the normal earth gravity field and then a quite important electrical properties and electrochemical processes disturbance, for both transport and reaction. This disturbance can lead to the modification of the local current density and to anode effects for example. In this work, a model experimental set-up is studied. The vertical pine electrode of small electro active surface area is surrounded with a large surface counter electrode. The hydrogen production is performed at the working electrode and effort is focused here upon the global electrochemical cell electrical performances. The polarization curves intensity vs. applied voltage are experimentally measured and presented for different factors such as: the electro active species concentration, nature and counter electrode diameter factors. © 2010 American Institute of Chemical Engineers AIChE J, 201

The goal of the present work is to present both experimental and numerical modelling of the gas production, during a two-phase electrolysis process: the alkaline water electrolysis. Numerical and experimental results obtained at normal and zero gravity will be presented. This possibility of zero gravity experiments allows the study of electrochemical performances in absence of natural convective transport. Particularly, such results allow input data identification and give accurate validation benchmark for numerical modelling.
