HOLMES-AEM – High-throughput catalysts for AEM electrolysis<\/h1>\n

In the HOLMES-AEM<\/strong> project, the ZBT<\/strong>, the University of Duisburg-Essen<\/strong> and the Fraunhofer IMWS<\/strong> are jointly developing a novel process for the production and characterisation of precious metal-free catalysts<\/strong> for alkaline membrane water electrolysis (AEM-WE).<\/p>\n<\/div>\n <\/div>\n

<\/h2>\n

In order for AEM technology to develop its full potential, high-performance and cost-effective catalysts<\/strong> are required. Up to now, screening methods have been time-consuming and only capture individual compositions. In the HOLMES-AEM project, we are therefore pursuing an innovative approach: laser-based synthesis<\/strong> produces catalysts from high-entropy alloys<\/strong>. Using targets with many different sectors, the composition<\/strong> of the nanoparticles is to be specifically varied<\/strong> during the ongoing ablation process. <\/p>\n

Innovation<\/h4>\n

A key unique selling point is the combination of this laser ablation with a spraying process<\/strong> for the production of graded membrane electrode assemblies (MEAs). This creates cells in which up to ten different catalyst compositions can be tested simultaneously – in just one experiment. The subsequent magnetic field-based operando analysis makes it possible to record the local activity of the individual areas non-invasively<\/strong> and under real operating conditions<\/strong>. <\/p>\n

Importance for SMEs<\/h4>\n

The results create new opportunities for companies along the entire value chain – from catalyst production<\/strong> and electrode manufacturing<\/strong> to measurement technology<\/strong>. SMEs in particular benefit from simplified access to newly developed materials and analytical methods that can be used for quality control and optimisation of electrolysers. <\/p>\n<\/div>\n<\/section>\n
