Solid polymer fuel cell and method of manufacturing the same

摘要

A solid polymer type fuel cell having a polyelectrolyte film having a proton conductivity; an anode electrode and a cathode electrode arranged on the opposite sides of the polyelectrolyte film; and a gas flow channel for supplying gas to the both electrodes, the anode electrode and the cathode electrode each being composed of a catalyst layer that is in contact with the polyelectrolyte film and a gas diffusion layer for allowing the diffusion of gas supplied from the gas flow channel to the catalyst layer, in which the gas diffusion layer included in the cathode electrode is constructed of a carbon-containing material and the surface of the carbon-containing material is modified to be hydrophilic.
