Electrochemical Degradation Test of The Catalyst for Polymer Electrolyte Fuel Cell (PEFC)
(Evaluation of Oxygen Reduction Performance)



The oxygen reduction profile of the catalyst for fuel cells is measured by Hydrodynamic Voltammetry (under Oxygen saturation).

Rotating Electrode (GC-RDE)

Hydrodynamic voltammetry
(under Oxygen saturation)

● Standard condition

①Sample Powder catalyst, 50mg~, H2O/CH3OH dispersion*
②Temperature Room Temperature
③Electrolytes* 1M-HClO4
④Atmosphere Under Oxygen saturation
⑤Potential* Initial potential 1.0V, ‎Final potential 0.2V vs RHE
⑥Scan rate* 0.01V/sec
⑦‎Rotational speed* 400, 900, 1600, 2500, 3600rpm

● Notes

The catalyst surface is electrochemically cleaned before measurements*.
(*CV Pt surface area measurement is Included) ANAC can propose other conditions than the standard condition according to customer’s requests.
