Performance specification

Insert the membrane, close the cell holder, start the software and begin the measurement.

The easy handling of DiLiCo single cell test system characterises the test stand for the analysis of PEM electrolysis membranes. The basis for the rapid membrane integration is the proven baltic quickCONNECTfixture system. With the help of compressed air, the compression force on the active cell surface can be variably adjusted, which is an important parameter for the operation of electrolysis membranes. The cell can be actively preheated or cooled before and during operation. The DI water supply has conductivity measurement and preheating for an optimal electrolysis process. The gases produced, hydrogen and oxygen, are dried, the flow rates measured and the proportions in the respective gas stream determined.

Test sequences, such as the time 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.
