Influence of processing on performance and durability of a reversal tolerant anode for a Proton Exchange Membrane Fuel Cell (PEMFC)

When no hydrogen is able to reach the Pt/C catalyst in the anode of an operating Proton-Exchange-Membrane Fuel Cell (PEMFC), the potentials of the cathode and anode will be reversed. During this fuel cell reversal, the potential of the anode rises and the Oxygen Evolution Reaction (OER) and Carbon Oxidation Reaction (COR) will occur. Applying an...
