Abstract
An electrode for water electrolysis which comprises a solid solution of graphite and polytetrafluorethylene impregnated with a catalyst mixture of platinum metal oxides, the solid solution being pressed and sintered on a reinforcing net of metal cloth, as well as a process for preparing the electrode. The electrodes are useful in large scale water electrolysis for the production of hydrogen.
