Anodes particularly suitable for use in electrolytic cells are prepared by coating an electrically-conductive substrate with a bimetallic oxide having a spinel structure of the formula M x Co 3-x O 4 where O<X≦1 and where M is a metal of Periodic Group IB, IIA or IIB. Also the coating contains therein, optionally, a modifier oxide, such as ZrO 2 . |
