In this work we analyze the applicability limits of the rotating ring-disk electrode (RRDE) technique for

quantifying the amount of oxygen produced during the oxygen evolution reaction (OER). We utilize a

state-of-the art IrO2 oxide as a carbon-free OER catalyst and La1xSrxMn0.5Co0.5O3d, x . 0.25 and 0.5

perovskites, which are studied in the presence of carbon. RRDE experiments are performed at different

IrO2 loadings under both potentiodynamic and potentiostatic modes. The experimental data allow us to

formulate the requirements to the experimental conditions necessary to avoid underestimation of the

oxygen yield.
