PROBLEM TO BE SOLVED: To provide a solid high polymer electrolyte fuel cell with an ion exchange membrane having high strength and low resistance of a current carrying part even if a membrane is thin. SOLUTION: In this solid high polymer electrolyte fuel cell, an ion exchange membrane 1 disposed between a pair of electrodes has a larger area than electrodes 4a, 4b, and has a current carrying part being in contact with the' electrode and a non-current carrying part making no contact with the electrode. A reinforcing material is contained in the boundary part 5 between the current carrying part and the non-current carrying part, and the reinforcing material is not contained in 70 % of the current carrying part. The ion exchange membrane is made of a perfluorocarbon copolymer containing a sulfonic group. |
