<P>PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell which has an appropriate humidifying structure and in which improvement in performance and durability is realized. <P>SOLUTION: This is a solid polymer fuel cell which obtains electromotive force by a battery reaction in which a cathode 30 is arranged on one side and an anode 3 is arranged on the other side through a polymer membrane 2, and an oxidizer gas is supplied to the cathode 30 and a fuel gas is supplied to the anode 3 respectively, and water is obtained by hydrogen and oxygen. A cooling water inlet side pipe line 5 is arranged adjacent to the location of humidification in the oxidizer gas passage 21 and/or fuel gas passage 34, and the cooling water 11 flowing in the cooling water inlet side pipe line 5 and the above polymer membrane 2 are made to contact. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
