Hydrogen Fuel Cells in Vehicles: Current Situation and Future Prospects

Hydrogen is emerging as a pivotal player in sustainable transportation, with hydrogen fuel cell electric vehicles (HFCEVs) gaining substantial traction. Despite the higher production costs compared to petroleum, hydrogen boasts a higher energy content by weight and produces zero toxic emissions. Advances in hydrogen storage, including cryogenic, pressurized tanks, and metal-organic frameworks, are overcoming density-related challenges. HFCEVs are making significant strides globally, particularly in South Korea, the United States, and China. By 2030, fuel cell prices are expected to be comparable with internal combustion engines due to advancements in technology. Enhanced control strategies, evolving safety measures, and supportive government policies are fostering the adoption of hydrogen as a viable clean power solution for future conveyance needs. Additionally, investments in infrastructure, such as hydrogen refueling stations, are expanding, further supporting the growth of HFCEVs. This paper explores the current advancements, challenges, and future outlook of hydrogen fuel cells in the automotive industry, highlighting their potential to revolutionize sustainable transport and contribute significantly to the reduction of greenhouse gas emissions.
