POLYMER ELECTROLYTE FUEL CELL |
摘要 |
The invention relates to a polymer electrolyte fuel cell comprising a polymer electrolyte film of hydrogen ion conduction; an anode and a cathode between which the electrolyte film is placed; a conductive separator having a channel through which fuel gas is supplied to the anode, and a conductive separator having a channel through which oxidative gas is supplied to the cathode. The conventional conductive separator uses a carbon material that is unlikely to be less costly, and an attempt has been made to use a metal plate in place of the carbon material. Since the metal plate is exposed to an oxidizing atmosphere at high temperature for a long time, however, corrosion may occur, disadvantageously causing the efficiency of power generation to decrease gradually. The polymer electrolyte fuel cell of this invention uses an acid-resistant conductive airtight elastomer as a conductive separator for substantial cost reduction. |
