Electrolysis

For the generation of hydrogen by electrolysis of water ZBT develops and operates laboratory test cells in order to characterise cell components like membranes, catalysts and electrodes. Materials which can be used at PEM-Electrolysis or at alkaline membrane electrolysis (AEM-Electrolysis: Anion Exchange Membrane Electrolysis) are under investigation.

Materials can be supplied by project partners or customers. Catalytic coating of electrode substrates can be also done at ZBT by means of spray or doctor blade coating processes.

For operation and characterisation of single cells or small stacks different test rigs and cell concepts are available. Current-voltage response curves and electrochemical impedance spectra can be measured and analysed.
