Graphene Catalyst Powers 200,000-Hour Fuel Cells

In this AI-generated episode of The Zero Emission Zone, we explore a cutting-edge study from Nature Nanotechnology on a platinum catalyst protected by graphene nanopockets. Designed for proton exchange membrane fuel cells in heavy-duty vehicles, this innovation delivers exceptional power density and a projected lifetime exceeding 200,000 hours—over seven times the DOE 2050 target. Tune in as we break down how nanotechnology is setting new standards for clean energy durability.
