Abstract
Polymer Electrolyte Fuel Cell (PEFC) spread gradually for home use. However, the PEFC is expensive because it uses platinum catalyst and expensive membrane as electrolyte, etc. Therefore, we have developed a new diagnostic system for reducing cost of the PEFC since 2004, and we have already established this system. This paper aims to elucidate the degradation factor distribution of the PEFC in the same electrode to apply this system. As a result, our diagnostics can clarified the degradation factor distribution, and we are going to be able to design a gas channel without degradation, and elucidate degradation mechanism of the PEFC using this system.
