Abstract
PEM electrolysers are considered as key technology to store electrical energy from renewable energies. In order to enhance the durability and increase efficiency an indepth understanding of the underlying electrochemical process is needed. In fuel cells segmented cells for locally resolved current density measurements were developed by DLR and are considered as a powerful tool to understand and optimize fuel cell operatio. Regarding their application in electrolyzers, the segmented cell needs first of all to be validated under electrolysis environment due to the diefferent process and working conditions as compared to fuel cells. The aim of this work was to test the potential of the segmented cell in electrolysis. For this purpose, the influence of different GDLs, flow fields and clamping torques on current density distribution have been analyzed. Additionally, the impact of important processes as degradation and water starvation on the current density distribution were studied using the segmented cell.
