Membrane electrode assembly and fuel cell unit |
摘要 |
The present invention aims to provide a membrane electrode assembly that can increase durability by increasing the strength of an extending part of a solid polymer electrolyte membrane, and can also reduce cost by minimizing the volume of the solid polymer electrolyte membrane used. In the present invention, an anode electrode is provided on one side of a solid polymer electrolyte membrane, and a cathode electrode is provided on the other side of the solid polymer electrolyte membrane. The solid polymer electrolyte membrane is formed such that its outer peripheral portion extends the anode electrode and the cathode electrode on both sides thereof. A framc-shaped first sealing member is closely contacted with the outer peripheral edge face of the anode electrode or the cathode electrode. The frame-shaped first sealing member coats and supports one face of the extending part of the solid polymer electrolyte membrane.
