Breakthrough US hydrogen fuel cell promises 200,000-hour life with minimal power loss
Scientists have developed a groundbreaking hydrogen fuel cell catalyst that could extend battery life to over 200,000 hours, far surpassing the U.S. Department of Energy's 30,000-hour target. The new design combines platinum nanoparticles encased in graphene and embedded in porous carbon, showing minimal power loss after 90,000 test cycles and potentially revolutionizing long-haul trucking with cleaner, more...
