Dr. Ronaldo P. Parreño Jr. is the lead researcher of ITDI driving the exploration of fuel cells, hydrogen, and other energy-related technologies as innovative energy and engineering solutions. His unique blend of expertise in chemistry, engineering, and materials science has been instrumental in exploring and developing essential engineering and advanced materials for energy technologies. The establishment of ITDI's Fuel Cell R&D and Testing Center, a direct result of his fuel cell technology development project, has enabled in-depth research into renewable and eco-friendly materials to improve the properties and performance of fuel cell components. His research works have yielded promising results, including the successful conversion of cotton waste to cellulose whiskers for hybrid membrane fillers and the potential of water hyacinth biochar as a low-cost electrode catalyst support. This led to the development of innovative solutions, requiring improvisation in the integration of lab-developed membranes and electrode catalysts into a 3-layered MEA, which demonstrated promising performance during testing in the Fuel Cell test station. He is actively working to further advance fuel cell technology by designing and optimizing the first prototype fuel cell stack assembly, performing validation and testing, and ultimately showcasing the technology in a pilot demonstration project. He aspires to establish partnerships with relevant stakeholders that will deliver fuel cell-integrat
