Experts believe that membrane electrolysis, which in principle works like a fuel cell in reverse, is particularly suitable for intermittent production with a highly fluctuating power supply. However, similar to the established process of alkaline electrolysis, systems for polymer membrane electrolysis so far have only been built in small quantities. Series production has only become attractive with the increased climate protection plans in China, Europe and the United States. By now, the first manufacturers are planning “gigafactories” where electrolyzers with a high degree of automation can be built at significantly lower costs.

By providing seals for electrolyzers, Freudenberg Sealing Technologies is contributing to sustainable hydrogen production based on solar and wind power. The seals are designed for automated production, enabling a rapid buildup of high manufacturing capacities as required for the “Green Deal”.
