1. An electrode for a membrane electrode assembly of a fuel cell, comprising:
a catalyst loaded material including an electrically conductive material and a catalyst disposed on the electrically conductive material;
an ionomer binder; and
a perfluorocarbon compound;
wherein the ionomer binder and the perfluorocarbon compound are disposed on the catalyst loaded material by simultaneously mixing a composition including the catalyst loaded material, the ionomer binder, and the perfluorocarbon compound, the composition formed by independently combining the catalyst loaded material, the ionomer binder, and the perfluorocarbon compound.
