Development of highly active anodes for anion exchange membrane electrolysers to enable low-cost green hydrogen – HighHy
The production of "green hydrogen" through electrolysis using renewable electricity is a key technology in the energy transition. So far, expensive and scarce noble metal catalysts have been used for this purpose. The HighHy project aims to develop and industrialize cost-effective and resource-efficient methods for water electrolysis.
In collaboration with the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM and the three New Zealand universities Canterbury, Auckland, and Wellington, electrodes for AEM electrolysis (Anion Exchange Membranes (AEM = Anion Exchange Membrane)) are to be designed and researched. Under the leadership of Prof. Dr.-Ing. Christina Roth, the Chair of Materials Processing Technology will contribute fundamental research to the development of catalyst materials, new methods of electrode production, and the characterization of materials. In the consortium, highly efficient anodes are to be designed, produced via environmentally friendly synthesis methods, and tested directly under real operating conditions. Cost-effective and resource-efficient catalysts that do not contain rare noble metals such as iridium but instead use nickel and manganese will be utilized.
The overarching goal of the HighHy R&D project is to further develop AEM electrolysis so that it can be used on an industrial scale for the production of green hydrogen.
