ABSTRACT:
A hydrogen evolution cathode for electrochemical reactions consists of a body formed of a powdered electrically conductive material embedded in a cured thermosetting resin and having a cathodically operative surface enriched with powder of a hydrogen evolution catalyst, the powdered conductive material preventing the diffusion of atomic hydrogen through the cathode body. The cathode may be incorporated in a bipolar electrode by bonding it to a thin sheet of valve metal coated with an anodic electrocatalytic material, the body being advantageously extended by projecting parts of electrically insulating cured resin.
