Application of Accelerated Testing and Statistical Lifetime Modeling to Membrane Electrode Assembly Development
Accelerated testing and statistical lifetime modeling are important tools in the development of durable membrane electrode assemblies (MEAs). There are several reasons for using accelerated tests, such as demonstrated durability improvement, marketing a product 's competitive advantage, and reduced product development time. Three types of accelerated testing are often used; screening tests, mechanistic tests, and lifetime tests. Accelerated lifetime tests are particularly useful when combined with statistical analysis to provide predictive capability for MEA lifetimes in “real life” conditions. This contribution outlines the main techniques for accelerated testing and important rules to follow for accurate results, such as observing the MEA failure modes for consistency.
