PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell which can increase output power more than a same-size ordinary fuel cell without improving the performance of a proton exchange film, and can adjust the output power as necessary. SOLUTION: At least one part of a hydrogen side collector 1 facing a hydrogen side electrode 2 is rough shaped, similarly at least one part of an oxygen side collector 5 facing an oxygen side electrode 4 is rough shaped, and a proton exchange membrane 10 formed in a tabular shape is pressured and applied in interposition between the hydrogen side collector 1 and the oxygen side collector 5, to have the proton exchange membrane 10 follow the rough shapes each formed on the hydrogen side collector 1 and the oxygen side collector 5. With this, contact area between each collector and the proton exchange membrane is increased and, accordingly, the output power is increased. Also, the output power can be adjusted by changing the rough shape. |
