This work reports on oxygen evolution reaction (OER), studied at nickel-coated carbon fibre (NiCCF) electrodes. The OER was examined comparatively on non-oxidized and electrooxidized NiCCF 12K50 tow materials in 0.1 M NaOH solution for the potential range: 1600-1800 mV vs. RHE. Electrochemical modification of NiCCF electrode results in significant facilitation of the OER kinetics, manifested through reduced, ac. impedance-derived values of charge-transfer resistance parameter and considerably modified Tafel polarization slopes.
