Current Fuel Cell Research: New Publications of the Chair of Technical Electrochemistry.

TUM.PtX News |

Proton exchange membrane (PEM) fuel cells generate electrical energy without direct CO2 emissions from the electrochemical reaction of hydrogen and oxygen to water. Thereby, PEM fuel cells distinguish themselves among others in high power densities and high flexibility. In June 2021 two new fuel cell related research articles of the Chair of Technical Electrochemistry were published in the Journal of the Electrochemical Society.

The recently published articles address degradation mechanisms of an anode-co-catalyst material at transient operation conditions (e.g. start-up/shut-down cycles) as well as reaction kinetics of the hydrogen oxidation and hydrogen evolution reaction in a so-called hydrogen pump.

Both publications are open and free accessible.
