A low-temperature polymer electrolyte membrane fuel cell (LT-PEMFC) is ideally suited to stationary and mobile applications. The reasons for this are its low operating temperatures and its advantages in intermittent operation. Several projects were carried out to further increase the potential for sustainability. In this context, sustainability means using the lowest possible proportion of petrochemical raw materials. The projects were performed under the call for proposals “Key Technologies for the Energy Transition” within the framework of Industrial Collective Research. The aim was to develop sustainable materials for individual components of the compound-based LT-PEMFC and to use them in fully bonded fuel cells. Part 1 of this article deals with the development of adhesives at substrate and coupon level. Part 2, to be published subsequently, addresses the transfer into the fuel cell as well as the sustainability assessment.
