Abstract

Proton Exchange Membrane Water Electrolyzers (PEMEL) are promising for the production of green hydrogen, but costs have to be reduced and lifetime has to be improved. In this study we investigate PEMEL with low catalyst loading achieved by Atomic Layer Deposition (ALD) and 3D printing of the electrodes. Degradation processes were characterized and allocated using different electrochemical and physicochemical methods. The cell setup was optimized using Distribution of Relaxation Times Analysis (DRT) of the Electrochemical Impedance Spectroscopy (EIS) measurements and the long-term performance of the optimized cell was investigated using different electrolytes (sulfuric acid and deionized water).
