ION CONDUCTIVITY-IMPARTING AGENT, ANODE CATALYST LAYER, MEMBRANE-ELECTRODE ASSEMBLY FORMED USING THE CATALYST LAYER, ANION EXCHANGE MEMBRANE FUEL CELL, AND METHOD OF OPERATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an ion conductivity imparting-agent for an anode catalyst layer of an anion exchange membrane fuel cell, good in conformability of a hydrocarbon-based anion exchange membrane and an anode catalyst layer at a junction interface therebetween, and high in initial performance, and further to provide an ion conductivity-imparting agent hardly deteriorated in performance even after long-term use.SOLUTION: In an ion conductivity-imparting agent for use in forming an anode catalyst layer of an anion exchange membrane fuel cell, an ion conductivity-imparting agent comprising a hydrocarbon-based anion exchange resin having an anion exchange capacity of 1.8-3.5 mmol/g is used.
