Patent number: 10056619Abstract: 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.Type: GrantFiled: October 26, 2012Date of Patent: August 21, 2018Assignee: Honda Motor Co., Ltd.Inventors: Seiji Sugiura, Hiroshi Shinkai, Kenichi Tanaka, Mihoko Kawaharada, Kenta Urata, Yukihito Tanaka, Takashi Kato

Patent number: 8911916Abstract: A fuel cell includes a membrane electrode assembly, a first separator, and a second separator. The membrane electrode assembly includes a solid polymer electrolyte membrane, a first electrode, a second electrode, and a resin frame member. The membrane electrode assembly includes a power generation section and a stepped section. The power generation section is located in an interior space of the resin frame member. The solid polymer electrolyte membrane is provided between the first electrode and the second electrode in the power generation section. The stepped section is located on an outer side of the first electrode. The solid polymer electrolyte membrane is provided between the second electrode and the resin frame member in the stepped section.
