A membrane electrode assembly comprises an anode electrode comprising an anode catalyst layer and an anode gas diffusion layer, a cathode electrode comprising a cathode catalyst layer and a cathode gas diffusion layer, a polymer electrolyte membrane interposed between the anode catalyst layer and the cathode catalyst layer, and a layer comprising a fluoroalkyl-phosphonic acid compound between at least one of the anode gas diffusion layer and the anode catalyst layer, the anode catalyst layer and the polymer electrolyte membrane, the polymer electrolyte membrane and the cathode catalyst layer, and the cathode catalyst layer and the cathode gas diffusion layer.
