Proton exchange membrane fuel cell accelerated testing

Abstract The durability of fuel cell components constitutes a major barrier towards their financial viabihty. Lifetime requirements include 5000 and 40 000 h for automotive and stationary applications respectively, and thus it is impractical to evaluate fuel cell components lifetime using prolonged time periods. Accelerated durability testing protocols for fuel cell components (proton exchange membrane, electrocatalyst and supports) have been developed to obtain cell component lifetimes in shorter e q)erimental time and are discussed in detail, along with fiiel/air impurities testing protocols.
