Summary: | The present invention provides a polymer electrolyte fuel cell, which is inexpensive and has an excellent efficiency of generating electric power, by using a material alternative to a perfluoroalkylene sulfonic acid polymer. The polymer electrolyte fuel cell comprises a pair of electrodes (
2, 3
) consisting of an oxygen electrode (
2
) and a fuel electrode (
3
) both having a catalyst layer (
5
) containing a catalyst and an ion conducting material; and a polymer electrolyte membrane (
1
) sandwiched between the two catalyst layers (
5
) of the both electrodes (
2, 3
). The above ion conducting material contained in the above polymer electrolyte membrane (
1
) or in the catalyst (
5
) layer of at least one of the above
electrodes (
2, 3
) comprises a sulfonated polyarylene having sulfonic acid side-chain groups. |
