<P>PROBLEM TO BE SOLVED: To provide a hydrocarbon polymer electrolyte capable of coping with both high ion conductivity and high anti-oxidation degradation characteristics, an electrolyte film using the same electrolyte, a film-electrode assembly, a fuel cell, and a fuel cell system. <P>SOLUTION: A polyazole electrolyte including a phosphoalkyl group is obtained by introducing directly or via an atom of oxygen or sulfur a phosphoalkyl group and phosphonic acid group to an aromatic ring of a polyazole-based polymer such as polyimidazole, polyoxazole, and polythiazole having superior anti-oxidation degradation characteristics. The polyazole electrolyte including the phosphoalkyl group is the polyoxazole of aromatic system containing of phosphoalkyl group and phosphonic acid group, the polythiazole, polyimidazole, a composition in which they are intermixed with each other, and copolymer. <P>COPYRIGHT: (C)2008,JPO&INPIT |
