The urgent need for sustainable energy solutions in light of escalating global energy demands and environmental concerns has brought hydrogen to the forefront as a promising renewable resource. This study provides a comprehensive analysis of the technologies essential for the production and operation of hydrogen fuel cell vehicles, which are emerging as a viable alternative to traditional combustion engine vehicles. It examines various fuel cell types, hydrogen storage methods, refueling logistics, and the role of batteries in fuel cell vehicles. The paper also explores the potential impact of advancements in artificial intelligence and quantum computing on the development of fuel cell vehicles. A global assessment reveals that South Korea (19,270) and the United States (12,283) are leading in the adoption of fuel-cell vehicles, particularly in the passenger car segment (82%), followed by buses (9.2%) and trucks (8.7%). The study highlights the challenges hindering fuel cell vehicle implementation, such as the need for consistent investment and collaboration among industry stakeholders to promote sustainable transportation systems. The analysis underscores the practicality of fuel cell vehicles, exemplified by models like the Toyota Mirai and Hyundai Nexo, which offer significant driving ranges and demonstrate the integration of advanced technologies. The paper discusses the environmental benefits of fuel cell vehicles, including their ability to operate with zero emissions when paired with renewable energy sources. Graphical Abstract

The increasing global demand for energy and the pressing challenge of environmental pollution necessitates a paradigm shift towards sustainable energy sources. Hydrogen, a viable renewable energy carrier, has the potential to substantially alleviate these concerns. This review offers a comprehensive exploration of the technologies imperative to the production and operation of fuel cell vehicles (FCVs), ranging from various fuel cell types, hydrogen storage methods, fueling station logistics, batteries in hydrogen vehicles, and the emerging influence of artificial intelligence and quantum computing. An analytical overview of global adoption patterns reveals significant geographical disparities, with the United States and South Korea at the forefront of FCV integration, primarily in the form of passenger cars, followed by buses and trucks. Asia emerges as the region with the highest proportion of FCVs. This paper also delves into the diverse challenges facing FCV implementation, shedding light on the essential role of continued investment in the evolution of sustainable transportation systems. Furthermore, it provides insights into the varying contributions of different companies in the field, demonstrating the collective effort required to advance this promising technology. The comprehensive exploration provided in this review aids in understanding the opportunities, challenges, and potential of hydrogen as an integral player in the future of sustainable transportation. The increasing need for energy carriers and the rise of environmental pollution have driven the exploration of renewable energy sources, with hydrogen being a promising option.
