Electrolyzers make it possible to greatly expand the use of renewable energies by producing hydrogen, which can be used to store clean energy. In order to facilitate the high-volume production of competitive stacks for PEM electrolysis in the near future, researchers at the Fraunhofer Institute for Solar Energy Systems ISE are investigating scalable processes such as slot-die coating and screen printing for the production of catalyst layers for the membrane electrode assembly (MEA). They have now developed catalyst inks for both production processes that enable the production of catalyst layers with lower iridium loading and high throughput. This significantly reduces the material and manufacturing costs for PEM electrolyzers.
