Currently, PEM electrolysis stacks are assembled primarily by hand with a low degree of automation. This project is being carried out as part of the BMBF lead project H2 Giga. The aim is to further develop new stacks to enable high degrees of automation and clock frequencies of a few hertz.
At Fraunhofer UMSICHT, an innovative, seal-free stack design based on welded cell clusters is being developed. As a "design of tommorow", the seal-free concept is to enable highly automated production from semi-finished products. Stack production should essentially be possible at one location in order to avoid long supply chains.
Fraunhofer ISE supports MAN ES and H-TEC in the conceptual development of a production line for stack production, as well as in the actual development of a large-area stack with conventional design. This includes, among others, investigation of the optimization potential of all components in the stack, qualification and quantification of components and component properties, development of corrosion protection coatings for metallic components and integration of the process step into manufacturing, definition and testing of test protocols in stack production, collaboration on the "Design of Tomorrow", development of test procedures and equipment as well as operating procedures within the production flow of an automated series production of PEM stacks.
