Operando investigation of Fe-N-C oxygen reduction catalyst using X-ray absorption and emission spectroscopies

This work will shed light on the behaviour of Fe-N-C catalysts during oxygen reduction reaction as well as on their deactivation mechanisms in an acid polymer electrolyte fuel cell (PEFC) device. X-ray absorption and emission measurements will be done operando in a custom made single-cell PEFC, providing new insights on the Fe-N-C structure.
