Kurzfassung
The fluctuating behavior of renewable energy sources hinders the widespread integration of those in a reliable electricity grid. Presumably, the wide operation range and rapid response of proton exchange membrane (PEM) electrolyzers can stabilize the grid, yet the degradation effects are not fully understood. The results presented here show no negative effect of dynamic operation at current 0.8, 1.6, 2.5 and 3.3 A cm-2, on commercial membrane electrode assemblies (MEA) with two different catalyst loadings. Conversely, the reduction of the loading of precious metal in the MEA leads to a cell voltage increase by 100 mV at 3.3 A cm-2. In addition, stack temperature correction of industrial facilities is necessary for proper comparison of cell potential and analysis of degradation mechanisms.
