PURPOSE: To provide a fuel cell of high output having high open electromotive force and terminal voltage by forming an ion exchange membrane as a specific double layer ion exchange membrane, in the fuel cell forming the ion exchange membrane as a solid-state high polymer electrolyte. CONSTITUTION: An ion exchange membrane is formed as a double layer ion exchange membrane comprising at least three layers, anode side ion exchange membrane layer, ion exchange membrane layer containing a catalyst (example; platinum) of promoting reaction of producing H2 O from H2 gas and O2 gas to preferably have 0.1 to 500mg/cm<3> this catalytic amount and a cathode side ion exchange membrane layer. Further, water content of the anode side ion exchange membrane layer is preferably set larger than water content of the cathode side ion exchange membrane layer by 5 to 50wt.% particularly by 10 to 30wt.%. |
