Abstract
Accelerating stress tests (ASTs) enable the analysis of degradation in adequate time. Here we present the aging characterization of three 8 cell short stacks of 120 cm² active surface area, running different AST protocols. By in- and ex-situ analysis we study the effects of catalyst amount, catalyst type and degradation at high current densities.
