MEMBRANE ELECTRODE ASSEMBLY WITH IMPROVED PERFORMANCE USING TWO COMPONENT FLUORINATED BLENDED ELECTROLYTE ADDITIVES

An electrode layer can have an electrically conductive material, a catalyst, an ionomer binder, and a perfluorocarbon compound. The ionomer binder forms hydrophilic regions on the electrically conductive material to support proton and water transport. The perfluorocarbon compound forms hydrophobic regions on the electrically conductive material to support oxygen solubility and transport. The electrode can be used in making a membrane electrode assembly and can be configured as a cathode thereof. Fuel cells and fuel stacks can include such membrane electrode assemblies.
