The possibility of in situ activation of oxygen evolving anodes and hydrogen evolving cathodes in alkaline water electrolysers has been investigated. It is possible to activate anodes by depositing on them cobalt oxide or iron oxide or an even more active mixture of both. In all three cases the oxyg...
