Membrane electrode assembly and method of making the same
Disclosed herein is a method of manufacturing a membrane electrode assembly (MEA) including directly depositing a liquid suspension containing a platinum precursor onto an ionically conductive membrane (e.g., proton-exchange membrane) that, when the platinum precursor deposit layer is reduced, provides a layer that will scavenge hydrogen that has diffused back through the membrane due to cell stack pressure differential.
