This paper deals with the electrochemical stability of the embedded powder clectrode of tungsten carbide (WC) catalyst. The results show that in acidic electrolytes WC exhibits a good electrochemical stability to hydrogen ionization reaction (HIR) and no oxide was formed on the electrode surface if the potential was less than 800 mv (vs. D H E). In basic electrolyte in parallel with hydrogen ionization reaction WC. itself undergoes electrochemical oxidation. Thus WC catalyst cannot be used in basic electrolyte medium.
