Improvement of Membrane and Membrane Electrode Assembly Durability
The world's first highly durable perfluorinated polymer-based membrane electrode assembly (MEA) for polymer electrolyte membrane fuel cells, under conditions of high temperature and low humidity, has been developed. The newly developed MEA, which is composed of a new perfluorinated polymer composite membrane, reduces the degradation rate to 1/100th to 1/1,000th of that of the conventional MEA. The new perfluorinated polymer composite MEA can be operated for more than 6,000 h at 120°C and 50% relative humidity.
