New roads and challenges for fuel cells in heavy-duty transportation

The recent release of hydrogen economy roadmaps for several major countries emphasizes the need accelerated worldwide investment in research and development activities production, storage, infrastructure utilization transportation, industry electrical grid. Due to high gravimetric energy density hydrogen, focus technologies that utilize this fuel has recently shifted from light-duty automotive heavy-duty vehicle applications. Decades cost-effective durable polymer electrolyte membrane cells must now be leveraged meet increased efficiency durability requirements market. This Review summarizes latest market outlooks targets truck, bus, locomotive marine Required changes fuel-cell system operating conditions meeting Class 8 long-haul truck are presented. necessary improvements materials integration also discussed against benchmark current passenger electric vehicles. Fuel increasingly being considered powertrains transportation. Cullen et al. survey technical challenges at both level transportation application outline roadmap future development.
