Sulfonated hydrocarbon polymers have been widely investigated as proton exchange membranes (PEM) for application in proton exchange membrane fuel cells (PEMFC). However, there is very little reports on their incorporation as ionomers in catalyst layers for hydrocarbon-based PEMFC. Hence, three kinds...
