An electrical device stabilized for long life operation comprising a cathode electrode including a porous layer of electrically conductive metal containing material, an electrolyte including an inorganic acid contacting the cathode electrode, and a cathode depolarizer including copper salt. A method of depolarizing an electrical device comprising the steps of forming a cathode electrode of layers of materials including a porous layer of electrically conductive metal containing material, contacting the cathode electrode with an electrolyte including an inorganic acid and a depolarizer including copper salt, reducing the copper salt to copper, and depositing copper on the cathode electrode as copper metal.
