Quantify and improve PEM fuel cell durability

The durability and performance of fuel cells have a major impact on the most important challenges facing fuel cell commerciallization including cost, mass production, system integration, functionality, and reliability. The aim of the present project was to systematically quantify and improve the durability of the PEM FC by the following approach: - Define degradation mechanisms; - Indentify and quantify factors that limit PEM FC durability; - Measure property changes in fuel cell components during life testing; - Life testing of materials; - Examine testing conditions; - Develop/apply methods for accelerated and off-line testing.
