Accelerated testing and statistical lifetime modeling

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 and three of the main reasons are listed here ... 

Utilizing tools such as accelerated tests and statistical lifetime modeling allow for early estimates of durability. There are three basic types of accelerated tests (1) screening tests are appropriate for measuring incremental improvements in component...
