Abstract
A gas generation apparatus is described which utilizes a novel catalytic oxygen evolving electrode for such electrochemical systems as electrolysis and oxygen concentrator cells. The oxygen concentration and the electroylsis cells include a catalytic cathode, an improved catalytic anode containing an active reduced platinoid electrocatalyst containing 5 to 60% ruthenium. The cathode and the novel catalytic anode are positioned on opposite sides of a cation exchange membrane with a source of direct current potential being connected between the two electrodes to concentrate gases such as oxygen or generate gases by an electrolysis process.
