Mapping Heterogeneous Ageing Inside Operational Hydrogen Fuel Cells
September 5, 2021 | 5 min read September 5, 2021 | 5 min readHydrogen fuel cells, devices which convert the energy stored in hydrogen gas to electricity, require large quantities of expensive platinum nanoparticle catalysts to electrochemically reduce O2 to water. The durability of this catalyst is currently a limiting factor in consumer automotive applications and the emerging hydrogen economy.
