Abstract:
1. An electrode catalyst layer comprising a composite particle having an electrode catalyst particle supported on an carbon black, activated carbon, graphite, and various metals, a perfluorocarbon sulfonic acid resin (component A) and a polyazole-based compound (component B), wherein polyazole-based compound is selected from the group consisting of compounds represented by chemical formulae (4), (5) and (6) found below; wherein R represents, an alkylene chain, a divalent group or a fluoroalkylene chain, each R1 independently represents a hydrogen atom, an alkyl, a phenyl group, or a pyridyl group, and “x” denotes a number from 10 or more to 1.0×107 or less; wherein “1” denotes a number from 10 or more to 1.0×107 or less, and R and R1 are defined in the same manner as in chemical formula (4); wherein “m” denotes a number from 10 or more to 1.0×107 or less, and R1 is defined in the same manner as in chemical formula (4); wherein the content of the composite particle is 20 to 95% by weight, the total weight of component A and component B is 5 to 80% by weight, and the weight ratio (A/B) between component A and component B is 1 to 499.
