TITLE OF THE INVENTION METHOD FOR BONDING A POROUS METAL LAYER TO A CERMET SURFACE ABSTRACT OF THE DISCLOSURE The bonding of a porous metal layer to at least one surface of a cermet is accomplished, without a supporting metal netting in the green cermet blank, by using a reducible metal oxide in the green cermet blank and a reducible metal oxide layer on the surface or surfaces of the green blank. In the following reducing sintering step the metal component in the green blank and the porous metal layer are formed simultaneously resulting in an intimate strong bond between the cermet blank and the porous metal layer. Both reducible metal oxides may be the same. The resulting product, such as an electrode-diaphragm-electrode structure is well suited for use in water electrolysis, chlorine alkaline electrolysis, and in fuel cells. 2234/ar - 1 -
