The rise in hybrid and electric vehicles is aiding efforts to decarbonize the transport industry, but electrifying heavy-duty vehicles like trucks and large buses remains a challenge. Fuel cells are promising for heavy vehicles, with proton exchange membrane fuel cells (PEMFCs) typically used. However, existing fuel cells have limitations hindering their widespread adoption. A research group at UCLA developed a platinum-based nano-catalyst to address this issue. The unique design of the catalyst featuring platinum nanoparticles protected by graphene nanopockets showed improved durability and stability over time. Initial tests revealed outstanding performance metrics, suggesting a fuel cell lifetime exceeding 200,000 hours. This innovation could lead to highly performing and durable hydrogen-based fuel cells for heavy-duty vehicles, contributing to emission reduction efforts in the transportation sector. The UCLA team aims to further enhance fuel cell performance by optimizing catalyst electrode structure and other components, highlighting the potential for future advancements in clean energy technology.
