Sustainable and efficient electrolysis stack
In the EU project ‘HYScale’, we are working with industry and research collaborators to develop innovative, high-performance materials and components for anion exchange membrane electrolysis (AEMEL).
One of the project’s main objectives is to construct the first single-stack AEMEL prototype with a power output of 100 kilowatts. Sustainable materials are to be used, eliminating the need for critical raw materials and ‘forever chemicals’ (per- and polyfluoroalkyl substances, or PFAS). Another key focus is scaling these technologies for industrial-scale production, with innovative and cost-effective design playing a crucial role. At the end of the HYScale project, we will integrate the stack into a functional electrolysis system and test it in an appropriate industrial environment.
Ultimately, this project helps raise hydrogen production to a new technological level – the HYScale process can produce hydrogen at current densities far exceeding the industry standard, and in a significantly more sustainable and efficient way.

With a focus on environmental responsibility, within the EU-project HYScale DLR is crafting a PFAS-free large-area AEM stack, designed to have a 400 cm² active surface area and 100 kW nominal power. The prototype with 5 cells is shown on the picture.
