NEW POLYMER ELECTROLYTE MEMBRANES FOR FUEL CELLS OPERATING ABOVE 100°C: - APPROACHES AND RECENT PROGRESS

Li, Qingfeng; Jensen, Jens Oluf; He, Ronghuan; Bjerrum, Niels

Proceedigns of the 1st European Hydrogen Energy Conference — 2003

The state-of-the-art of PEMFC technology is based on perfluorosulfonic acid (PFSA) polymer membranes operating at a typical temperature of 80°C. The newest development in the field is alternative polymer electrolytes for operation above 100°C. This paper is devoted to a review on the development
