Scalable hydrocarbon CCMs for next-generation technologies (105°scaled)

In 105°scaled, hydrocarbon-based membrane electrode assemblies (MEAs) are being developed for both fuel cells and electrolysis to be competitive with established PFAS-based MEAs.

The 105°scaled project focuses on the further development of two important technologies: alkaline membrane electrolysis and the hydrocarbon proton exchange membrane fuel cell.

Hydrocarbon MEAs for proton exchange membrane fuel cells at 105°C enable the use of smaller cooling systems, resulting in cost advantages. This property is particularly important for heavy-duty applications and is a necessary prerequisite for the possible use of fuel cells in aircraft. Therefore, an MEA based on hydrocarbon polymers is to be developed in 105°scaled that makes this possible. The particular focus of the project is on controlling and improving water management in the Pt/C catalyst-based electrodes.

The development of hydrocarbon MEAs for stable, iridium-free AEM electrolysis operation is of great importance because iridium is extremely rare and costly. By using alternative materials, costs can be reduced and resources can be conserved. The 105°scaled project aims to bring CCMs for AEM electrolysis much closer to market readiness. By developing tailor-made test stands for AEM electrolysis at Hahn-Schickard, this development can be significantly accelerated.
