POLYMER ELECTROLYTE TYPE FUEL CELL

摘要

A polymer electrolyte type fuel cell characterized in that a cathode and an anode consist of catalyst particles, hydrogen-ion-conductive polymer electrolytes, conductive porous base materials and water repellent agents, and the water repellency of at least one of the cathode and anode varies in a thickness direction or a surface direction. Such a position-dependent change in the water repellency level of an anode or cathode can provide an excellent polymer electrolyte type fuel cell having high discharge characteristics, especially, high current-voltage characteristics in a high current density region.
