摘要: Abstract Implementation of polymer electrolyte fuel cells (PEMFCs) for stationary power applications requires the demonstration reliable cell stack life. One most critical components in and that likely to ultimately dictate life is membrane electrode assembly (MEA). This publication reports results a 26,300 h single test operated with commercial MEA at conditions relevant applications. In this experiment, ultimate was dictated by failure membrane. addition, performance degradation rate determined be between 4 6 μV h−1, operating current density 800 mA cm−2. AC impedance analysis DC electrochemical tests (cyclic voltammetry polarization curves) were performed as diagnostics during on completion test, understand materials changes occurring test. Post mortem analyses also performed.
