Disclosed is a bipolar electrolyzer having individual bipolar units. Each of the bipolar units has a steel cathodic member and a valve metal anodic member in back-to-back configuration. The bipolar electrolyzer is characterized in that the cathodic member is spaced from the anodic member defining an electrolyte tight compartment therebetween, and that the bipolar unit further has conduit means extending outwardly from between the anodic member and the cathodic member. Also disclosed is a method of electrolysis in a bipolar electrolyzer which method is characterized by collecting hydrogen between the anodic and cathodic members of the bipolar unit and removing the hydrogen so collected through hydrogen removal means.
