Abstract
A membrane electrode assembly with protective film includes a MEA and protective films. The MEA includes a cathode, an anode, and a solid polymer electrolyte membrane interposed between the cathode and the anode. The protective films are joined on the outer end of the solid polymer electrolyte membrane. The membrane electrode assembly has a power generation area and an edge-vicinity area. Recesses for receiving the edge-vicinity area including outer ends of the cathode and the anode are formed in outer portions of a cathode-side separator and an anode-side separator which contact the MEA.
