Sub-project: Development and modeling of cell, stack and system concepts - investigation of bubble behavior inside the cell
The content of the project is the further development of electrodes for alkaline electrolysis and the scaling of the production route in order to meet the demands of the GW electrolysis industry.
The aim of the Fraunhofer IFAM sub-project is firstly to research and develop scalable, highly active, load-stable and durable electrodes with high raw material availability, and secondly to simulate the gas-electrolyte flow in an electrolyser cell. An accumulation of gases inside the cell must be avoided so that the electrolyte wets the entire surface of the electrode and it is therefore fully active. The complex physical-electrochemical relationships of the multiphase flow in the electrode chamber with simultaneous gas development of the electrochemical reactions are mapped in the computer model.
