Platinum, graphene-protective layer and porous carbon extends fuel cell life beyond 200,000 hours, paving way for clean long-haul trucking


"polymer electrolyte membrane fuel cell... 1.08W/ square cm power output, same performance as conventional batteries weighing up to 8X more... diminished catalytic performance: alloying elements leach out over time, voltage cycles required to power heavy-duty vehicles are demanding... overcome nesting graphene-encased nanoparticles inside porous Ketjenblack carbon powder... <1.1% power loss after 90K square-wave voltage cycles"
