AlkaCell - New materials and structures for alkaline fuel cells

Duration: January 2019 - July 2022

Funding: Vector Stiftung

GEMEINSAM RICHTUNG ZUKUNFT - Die Vector Stiftung

In the project AlkaCell we develop PGM-free electrocatalysts for alkaline fuel cells. We focus our efforts on Fe-based materials for the oxygen reduction reaction (ORR) and Ni-based materials for the hydrogen oxidation reaction (HOR). Advanced material characterization and activity and stability studies on the RDE level are done in our lab while AEM studies are realized in cooperation with Dr. Vierrath from the EES group at the IMTEK (University of Freiburg). 

The electrocatalysts we developped in this project so far are very promising and a publication on material design, RDE and MEA activities is in preparation.
