Abstract

A hydrogen evolution cell which on passage of an electric current liberates an amount of hydrogen proportional to an amount of current flowing through, includes an electrochemically oxidizable anode, a hydrogen cathode, an electrolyte and a casing surrounding the same, wherein the hydrogen cathode is associated structure of at least one pocket defining a hollow space or defines a hollow space in the presence of hydrogen overpressure or wherein the cathode forms such a pocket.
