New research released today by scientists at Queen Mary University of London suggests that graphene could be used to make more durable hydrogen fuel cells for cars.
Platinum is the most widely used catalyst for fuel cells, but its high cost is a big problem for commercialisation. To address the issue, commercial catalysts are typically made by decorating tiny nanoparticles of platinum onto a cheaper carbon support, however the poor durability of the material greatly reduces the lifetime of current fuel cells.
But in a new development, the university researchers have confirmed the durability of the graphene-based catalyst using a type of test based on those recommended by the US Department of Energy (DoE), known as accelerated stress tests.
