    摘要： 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.

    摘要： An electrode structure having a pair of electrode catalyst layers and a polymer electrolyte membrane held between both the electrode catalyst layers is provided. The polymer electrolyte membrane is a sulfonate of a hydrocarbon-based polymer comprising a main chain in which two or more benzene rings are bound together directly or through a divalent group. The membrane includes 5% or more by weight of water coordinated to protons of sulfonic acid groups. The polymer electrolyte membrane may include a fluorine-containing ion conducting polymer such that the ratio of fluorine content in the polymer electrolyte membrane to the fluorine content in the electrode catalyst layers is in the range of from 0.2 to 2.0. The electrode structure constitutes a fuel cell, which generates power when oxidizing gas is supplied to the one side of the electrode structure and reducing gas to the other side.
