Innovations in Hydrogen Fuel Cells: Greener Transportation Future

Hydrogen-powered fuel cell vehicles (HFCVs) are increasingly gaining attention as a clean, sustainable alternative to fossil fuel-based internal combustion engine (ICE) vehicles and battery electric vehicles (BEVs). This work provides comprehensive insights into the latest technological advancements, current status, key challenges, and prospects of hydrogen fuel cell technology in the automotive sector. The widespread adoption of HFCVs hinges on pivotal breakthroughs in several critical areas that collectively enhance overall performance, including catalyst materials, membrane technologies, hydrogen storage solutions, system integration, and thermal management strategies. This study highlights the importance of developing innovative, costeffective non-platinum-based catalysts that provide substantial enhancement in catalytic efficiency, durability, and overall performance. Emerging hydrogen storage technologies, such as solid-state and cryo-compressed systems, show great promise in addressing the efficiency and safety limitations of conventional compressed hydrogen gas storage. The transition toward sustainable mobility through HFCVs will require coordinated efforts, including the generation of renewable electricity for green hydrogen production, supportive government policies, strategic incentives, and robust research and development initiatives aimed at enhancing fuel cell durability and infrastructure. These proactive measures are essential to overcoming the technological and infrastructural barriers and achieving a cleaner, more sustainable transportation future.
