AEM Water Electrolysis<\/h1>\n

Anion exchange membrane water electrolysis (AEM-WE) combines the advantages of alkaline electrolysis with those of polymer membrane technology. It enables cost-efficient hydrogen production through the use of precious metal-free catalysts. At the same time, proven manufacturing and design principles from PEM technologies can be utilised. <\/h4>\n
\n
\n

We cover the entire value chain \u2013 from the development and synthesis of precious metal-free catalysts<\/strong> to the manufacture and processing of membrane electrode assemblies (MEAs)<\/strong> to system integration and long-term testing<\/strong>. In addition to material development, we optimise production processes<\/strong> and support scaling from the laboratory phase to large-scale implementation. <\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n<\/section>\n\n\n

Research and applied development for industrial applications<\/h2>\n
\n
\n

Our focus is on the manufacture and characterisation of new precious metal-free catalysts<\/strong> and the development of innovative MEA manufacturing processes<\/strong>. Various coating techniques are used, such as spray processes and large-area doctor blade and slot die coating processes. <\/p>\n

 <\/p>\n

In tests, we use measuring cells with specially adapted flow fields<\/strong>. Our measuring equipment enables the characterisation of single cells with active areas of 5 to 25 cm\u00b2 in long-term tests under real operating conditions, including up to 8 bar for AEM water electrolysis. We also offer electrochemical characterisation, \u00b5XRF mapping and layer thickness analyses for the investigation of catalyst layers. <\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n

Development<\/h2>\n
\n
\n

We develop and optimise materials for AEM electrolysis, including membranes<\/strong>, ionomers<\/strong> and catalysts<\/strong>. In addition to our own catalyst synthesis, we work with partners to research precious metal-free materials for use in AEM electrolysers. We also develop innovative production processes<\/strong> for membrane electrode units. <\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n

Production<\/h2>\n

Our expertise includes various coating processes<\/strong>, including spray processes and large-area doctor blade and slot die processes. We advise on the transfer of laboratory-scale coatings to industrially scalable processes such as roll-to-roll processes and carry out quality assurance analyses<\/strong>. <\/p>\n<\/div>\n <\/div>\n

Measurement and testing<\/h2>\n
\n
\n

For the characterisation of AEM water electrolysers, we have measuring cells<\/strong> with active areas of 5 to 25 cm\u00b2 that allow pressures of up to 8 bar. Our test benches<\/strong> allow long-term tests according to predefined test protocols with a current runtime limit of 100 hours. <\/p>\n

 <\/p>\n

In addition to electrochemical investigations, the quality assurance<\/strong> of MEA manufacturing processes is carried out using high-resolution analytics, including \u00b5XRF mapping and layer thickness analyses. In order to simulate real-life operation, specially developed flow field inserts are used in the test benches. <\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n
