Abstract:
1. An electrode paste, comprising an electrode electrolyte for a polymer-type fuel cell, catalyst particles, and a solvent, wherein the electrode electrolyte comprises a polyarylene-based copolymer including a sulfonic acid group, wherein the copolymer contains a repeating constitutional unit represented by the following Formula (I): (in Formula (I), Y denotes at least one kind of structure selected from the group consisting of —CO—, —SO 2 —, —SO—, —CONH—, —COO—, —(CF 2 ) I — (I is an integer of 1 to 10), and —C(CF 3 ) 2 —; W denotes at least one kind of structure selected from the group consisting of a direct bond, —CO—, —SO 2 —, —SO—, —CONH—, —COO—, —(CF 2 ) I — (I is an integer of 1 to 10), —C(CF 3 ) 2 —, —O—, and —S—; Z denotes a direct bond or at least one kind of structure selected from the group consisting of —(CH 2 ) I — (I is an integer of 1 to 10), —C(CH 3 ) 2 —, —O—, —S—, —CO—, and —SO 2 —; R 30 denotes at least one type of group derived from a compound selected from the group consisting of pyrrole, thiazole, isothiazole, oxazole, isoxazole, imidazole, imidazoline, imidazolidine, pyrazole, 1,3,5-triazine, pyridine, pyrimidine, pyridazine, pyrazine, indole, quinoline, isoquinoline, burine, tetrazole, tetrazine, triazole, carbazole, acridine, quinoxaline, quinazoline, indolizine, isoindole, 3H-indole, 2H-pyrrole, 1H-indazole, purine, phthalazine, naphthyridine, cinnoline, pteridine, carboline, phenanthridine, perimidine, phenanthroline, phenazine, phenarsazine, phenothiazine, furazan, phenoxazine, pyrrolidine, pyrroline, pyrazoline, pyrazolidine, piperidine, piperazine, indoline, isoindoline, and quinuclidine, and derivatives thereof, having at least one substituent represented by —SO 3 H, —O(CH 2 ) h SO 3 H, or —O(CF 2 ) h SO 3 H (h is an integer of 1 to 12); and p denotes an integer of 0 to 10; q denotes an integer of 0 to 10; r denotes an integer of 1 to 5; and k denotes an integer of 0 to 4, and in single lines at the ends of each constitutional unit, a single line not showing a substituent on one side thereof means coupling with the adjacent constitutional unit).
