PROBLEM TO BE SOLVED: To provide an electrolyte film which can obtain high ion conductivity by introducing relatively little amount of ion exchange group, and to raise CO-resistant nature of an electrode and its durability, by mitigating or making needless to humidify the electrolyte by accessory machine, in a low-temperature operating type fuel cell. SOLUTION: The electrolyte film 10 is provided with a film support body 12 which has a through hole 12a penetrating in a thickness direction, and an ion conductive substance 14 introduced into the inside of the through hole 12a. Moreover, the fuel cell has a film electrode zygote 20 which joins an anode 40a and a cathode 40b to both sides of the electrolyte film 30 having the structure such as the above descriptions. Moreover, the anode 40a and the cathode 40b are provided with catalyst layers 44a and 44b which gaseous phase side surfaces of the electrolytes 50a and 50b in the catalyst layer are covered with water repellant layers 52a and 52b. It is desirable to use a fluoride system material as the water repellant 52a and 52b. |
