Hy²Cycle

The overall objective of the Hy²Cycle joint project is to develop resource-efficient and recyclable cells and stacks for fuel cells (FC) and electrolysers (EL). The primary focus of this study is on concepts for high-pressure alkaline EL/FC technologies, with the objective of enhancing efficiency through the augmentation of pressure. Additionally, the study explores a reversible cell concept for PEM EL/FC, with the aim of promoting efficiency enhancement. The fundamental objective of both concepts is to adopt a recycling-friendly approach, which is why novel recycling processes and influences on damage are being tested and implemented from design to operation in the sense of a circular economy. The development of new, suitable recycling processes is therefore essential. In this regard, there is an ongoing development of thermal, mechanical and chemical processes that are adapted to the specific conditions of electrolysis cells. During operation, the influence and durability of recycled materials will be considered, and estimates of degradation and age prediction will be carried out using simulations. Energy-efficient and resource-saving EL and FC are fundamental to the success of a hydrogen economy. The Saxon Hydrogen Union is a collaborative initiative that integrates Saxony's three foremost research institutions, specialising in the domains of EL, FC and material recycling.
