Brief description

The overall objective of the joint project Hy²Cycle is the development of resource-efficient and recyclable cells and stacks for fuel cells (FC) and electrolyzers (EL). The focus is on concepts for high-pressure alkaline EL/ FC technologies to increase efficiency by increasing pressure and a reversible cell concept for PEM EL/ FC. The focus of both concepts is the consideration of a recycling-friendly approach, which is why new recycling processes and influences on damage are being tested and implemented from design to operation in the sense of a circular economy. This requires the development of new, suitable recycling processes. To this end, thermal, mechanical and chemical processes are being developed that are adapted to the special conditions for electrolysis cells. During operation, the influence and durability of recycled materials will be examined and simulations will be used to estimate degradation and predict ageing. Energy-efficient and resource-saving EL and FC are the basis for a successful hydrogen economy. The Saxon Hydrogen Union links Saxony's three best competence centers in their respective fields for the research and development of EL, FC and their material recycling.
