Developing low-cost electrode systems based on improved iridium-titanium oxide catalyst layers to be used as anodes in PEM-electrolysis
The innovative approach in this research project is based on an optimised electrode architecture, in which a titanium oxide nanoparticle coating is applied onto a porous titanium substrate that acts as carrier for electrochemically precipitated iridium particles. The improved electrode architecture increases the electrode surface, which in turn means that the noble metal catalyser can be used more effectively, and this reduces the costs of the electrodes for PEM electrolysis. Consequently, thanks to the simplified cell structure, the investment costs for PEM electrolysers are lowered and SMEs can find themselves in a position to successfully market this technology and establish new areas of business.
The final objective is to develop a demonstration electrode system for electrolysis cells in a hydraulically pressed test system. Commercially available membranes and graphite-based cathodes are pressed together with the anodes in development in order to create the membrane electrode assemblies (MEA); their performance will then be compared with commercial electrode systems.
