Effect of Electrolyte Polymer Acidity on Platinum Degradation in MEAs

We fabricated MEAs having the EW200 or EW1000 electrolyte in the catalyst layer. The potential cycle test (square-wave potential cycling between 0.6-1.0 V with a pulse width of 3 s) was performed for these MEAs to evaluate the ECA change from CVs. It was revealed that the ECA decrease of the EW200 M...
