The cathode catalyst layer void volume of the proton exchange membrane fuel cell (PEMFC) determines the available three‐phase regions and routes of mass transfer in the membrane electrode assembly (MEA). In this paper, four MEAs with different void volume of cathode catalyst layer have been made and their performance was evaluated and analyzed. The results show that for the MEA with cathode catalyst...
The major objectives of this study are to identify the best activation procedure between commonly used procedures that can significantly reduce the conditioning duration and to understand the change in interfacial properties during conditioning. In order to do that, three on‐line activation procedures were employed for activating of identical MEAs in PEMFC and studied by polarization curve and electrochemical...
