Abstract :

One of the primary objectives to increase the durability of Proton Exchange Membrane Fuel Cells (PEMFC), particularly for transportation applications, is to reduce the circumstances known to accelerate degradations during start-up and shut-down. These kinds of extreme situations are often mimicked with the use of accelerated stress tests like cyclic voltammetry cycles. The findings provided in this study imply that the degradations induced by this approach do not correlate to those observed under actual operating circumstances, despite the fact that it is simple to apply.
