PROBLEM TO BE SOLVED: To provide a solid high polymer molecule electrolyte fuel cell self- moisturizing and its moisturizing method which is simple in system and compact in equipment. SOLUTION: In the solid high polymer molecule electrolyte fuel cell equipped with an anode electrode and a cathode electrode having a catalyst electrode layer 40 which sandwich an electrolyte film 31, and an anode side separator 32a and a cathode side separator 32k which have a gas distribution slot 50. An anode gas and a cathode gas are made of flow face to face, furthermore, a moisturizing section 41 which makes moisture transfer through the electrolyte film from one side to the other of the reaction gas flowing oppositely on both sides of the electrolyte film, is arranged at both sides upstream and downstream the reaction gas, in the outside contiguous section of the catalyst electrode layers sandwiching the electrolyte film. Then, the electrolyte film 31 is moisturized with water generated in fuel cell reaction. |
