Project goals

Zn-air batteries (ZAB) and fuel cells (FC) are the green solution for the growing need for energy conversion technologies. Although, an alternative catalyst to Pt is needed for ZABs and FCs. In recent years, the use of polymer-derived materials for the preparation of non-precious metal oxygen reduction reaction (ORR) catalysts for ZAB and FC applications has gained a lot of interest. This is due to such properties as high electrocatalytic activity, long-term stability and low cost.

Assoc. Prof. Kaido Tammeveski’s group at University of Tartu (UniTartu) has done extensive research in this area and prepared several polymer-based catalysts showing good ORR performance. They have also collaborated with Dr. Michaela Wilhelm/Prof. Kurosch Rezwan’s group from University of Bremen (UniBremen) and published a joint paper in 2019, where polymer-derived ceramic materials prepared at UniBremen were studied as ORR catalysts for FC application at UniTartu. Prof. Kurosch Rezwan’s group also has the equipment and knowledge necessary for ZAB testing, which are currently not available in Tartu. Therefore, the present project gives an opportunity for a researcher from UniTartu to test their catalysts in ZAB at UniBremen. As a result, Estonian-German joint papers will be published and the ZAB testing technology for UniTartu will be obtained.
