FIELD: electricity.
SUBSTANCE: layered structures are proposed, which have a porous ceramic layer and a porous metal base or a layer of a current collector, engaged through mechanical mutual engagement, provided due to mutual penetration of layers and/or roughness of a metal surface. Porous layers may be impregnated with a catalytic material.
EFFECT: invention makes it possible to reduce cost and increased reliability of electrochemical elements.
