In the publication: "Proton exchange membrane water electrolysis at high current densities: Investigation of thermal limitations" [https://doi.org/10.1016/j.ijhydene.2019.11.144], research associate Maximilian Möckl uses measurements to demonstrate novel high-current-capable PEM electrolysis units with current densities of up to 25 A/cm². Series of measurements on prototype cells also validate a model of the heat balance of the future-oriented PEM cell. Further current research on test vehicles is now focusing in particular on the aging and long-term stability of PEM electrolyzers.
In addition to the experimental work, the chair has also recently made significant progress in model development: For example, the open source modeling tool SimSES was extended to include a representation of the power-to-gas storage chain: In the currently available release of the freely accessible software tool, a corresponding storage configuration can be selected, and the techno-economic performance in a concrete grid application can be compared with other storage systems (for example, the lithium-ion battery and redox flow battery).
