Abstract
A polymer electrolyte membrane fuel cell is provided. The polymer electrolyte membrane fuel cell includes a phosphoric acid-doped polyimidazole electrolyte membrane and a complex catalyst. In the complex catalyst, an alloy or mixture of a metal and a chalcogen element is supported on a carbon carrier. The polymer electrolyte membrane fuel cell exhibits further improved long-term operation, power generation efficiency, and operational stability at high temperature. The complex catalyst can be produced by a simple method.
