    摘要： A solid polymer fuel cell includes an electrolyte membrane having a polymer ion-exchange component, and an air electrode and a fuel electrode between which the electrolyte membrane is sandwiched. Each of the air electrode and the fuel electrode can be formed of a polymer ion-exchange component and a plurality of catalyst particles including a catalyst metal carried on surfaces of carbon black particles, and includes no third component. When a moistening for maintaining the electrolyte membrane in a wet state is carried out from both of the side of the air electrode and the side of the fuel electrode, the carbon black particles have a water-repellent property such that an amount A of water adsorbed under a saturated steam pressure at 60° C. is equal to or smaller than 80 cc/g, and a ratio Wp/Wc of a weight Wp of polymer ion-exchange component incorporated to a weight Wc of carbon black particles incorporated is set in a range of 0.4≦Wp/Wc≦1.25.

    摘要： A solid polymer electrolyte fuel cell has a fuel electrode and an oxidant electrode, which face each other via a solid polymer electrolyte membrane. A metallic complex is added to the fuel electrode of the solid polymer electrolyte fuel cell. Since this metallic complex adsorbs oxygen as the oxygen partial pressure at the fuel electrode increases and desorbs oxygen as the oxygen partial pressure decreases, oxygen produced when a reverse voltage is generated can be removed efficiently. It may be possible to prevent the deterioration of or damage to a catalyst material of the fuel cell and the electrolyte membrane.

    摘要： A method for fabricating a seal-integrated separator for a fuel cell is presented, with which seals can be accurately positioned and the assembling time for the fuel cell units may be greatly reduced. The method comprises the steps of: forming a through hole in the separator body; providing a first mold having grooves respectively positioned corresponding to the inner and outer seals disposed on one side of the separator body, a connecting cavity for forming a seal bridge at least partially connecting the inner and outer seals to each other at a position corresponding to the through hole, and at least one gate communicating with each of the grooves, and a second mold having grooves respectively positioned corresponding to the inner and outer seals disposed on the other side of the separator body, and a connecting cavity for forming a seal bridge at least partially connecting the inner and outer seals to each other at a position corresponding to the through hole; holding the separator body between the first mold and the second mold; and injecting melted seal material to form the seals into each of the grooves in the first mold by supplying the melted seal material into the gate and injecting a portion of the melted seal material into each of the grooves in the second mold via the through hole. Through this method, a seal-integrated separator having first to fourth seals which are integrated on both sides of the separator body is fabricated.

    摘要： In this fuel cell, among a pair of separators in which an electrically conductive portion which is made from an electrically conducting material is surrounded by an insulating portion which is made from an insulating material, a cell side terminal is provided in the inner surface of the insulating portion of at least one said separator, and extends from its interior circumferential side to its outer perimeter side, and is able to electrically connect the interior and exterior of the cell. This cell side terminal is made from a metallic plate, and its inner circumferential side end portion contacts the membrane electrode assembly, while its outer perimeter side end portion extends to the outer perimeter side of the insulating portion. This outer perimeter side end portion can be connected to a measurement side terminal.
