Abstract:
A membrane electrode assembly includes an electrolyte membrane, an anode disposed on one face of the electrolyte membrane, and a cathode disposed on the other face of the electrolyte membrane. The electrolyte membrane has a non-electrode-forming region where the cathode is not disposed on the surface of the non-electrode-forming region and an electrode-forming region where the cathode is disposed on the surface of the electrode-forming region. The non-electrode-forming region has a thin membrane region where the membrane is thinner than that in the electrode-forming region. The drop in power generation efficiency by water generated at the cathodes is prevented.
