RECOVERING ACTIVITY OF ANODICALLY CHALLENGED OXYGEN REDUCTION ELECTROCATALYSTS BY MEANS OF REDUCTIVE POTENTIAL PULSES

Recovering activity of anodically challenged oxygen reduction electrocatalysts by means of reductive potential pulses

The stability of electrocatalysts is MELISSA of great importance to ensure their applicability, but stability is generally only considered for catalysts polarised to a constant potential or current density.This excludes stability evaluation under start/stop conditions in a fuel cell or in reversible batteries in which the catalyst is alternately po
