Insert the membrane, start the software and start to measure The simple handling of the DILICO Hydrogen cell test system characterizes the test stand for analysing PEM electrolysis membranes.

The proven baltic quickCONNECTfixture system serves as the basis for quick membrane integration. Compressed air can be used to variably adjust the compression force on the active cell surface, which is an important parameter for the operation of electrolysis membranes. The cell can be actively preheated or cooled before and during operation in order to achieve optimum conditions for comparative measurements. The DI water supply features conductivity measurement and preheating for an optimized electrolysis process. The hydrogen and oxygen gases produced are dried, the flow rates are measured and the proportions in the respective gas flow are determined so that mechanical problems on the cell components can be visualized. Test sequences, such as the temporal recording of current and voltage characteristics and other parameters, can be programmed in the software in a script and thus enable reproducible measurements to be carried out. DILICO CURR TEMP for the distributed measurement of currents and temperatures on the membrane is included as standard for characterising the electrolytic cell. The measurement method visualizes the various effects on the current and temperature distribution across the membrane surface, such as drying, flooding, thermal hotspots, undersupply of gases, the behaviour of the contact pressure of the cell and the aging behaviour in different regions of the membrane.
