Fields of activity

The Institute of Sustainable Energy Technology and Mobility at Esslingen University of Applied Sciences undertakes interdisciplinary work in the field of sustainable mobility and energy systems in the broadest sense.

INEM’s objective is to concentrate and enhance the know-how existing in all faculties in order to create a competence centre for Baden-Württemberg in this field.

Realisation of a semi-automatic coating process for low-temperature fuel cell membranes
Membrane fuel cells (PEM) have a number of advantages over the alkaline cells which have long been standard. Their membranes must be coated with catalytically active materials which are often based on expensive platinum. This process is not necessary when the advantages of the alkaline cell and the PEM cell are combined. The objective of the work was to automate the production of an anion-conducting membrane which could subsequently be used in a fuel cell. A semi-automatic membrane coating system was designed, built and optimised by means of spraying experiments.

Concept and design of a PEM high-pressure electrolyser stack
If the storage of hydrogen is to be cost effective compared to other energy storage concepts, the gas has to be compressed.  Nowadays, it is normally compressed after the electrolysis stage by means of a compressor. To improve the overall efficiency, the need to compress the hydrogen with the compressor should be obviated and the compression achieved through the hydrogen generation process. The project objective was to design and build a PEM high- pressure electrolyser stack which would then be combined with a pressure vessel to produce and simultaneously compress hydrogen and oxygen.
