Abstract
On a sheet steel carrier a suspension containing a binder and nickel powder r a powder containing a nickel alloy in a volatile suspension medium is applied, with or without an additional pore-forming material, and the sintered to produce a porous sintered layer. Alternatively, this sintered layer can be obtained by depositing and consolidating the powdered mixture on the carrier with the aid of a plasma gun. A nickel/zinc alloy is then precipitated electrolytically on the sintered material thus produced and, finally, the zinc is dissolved out by dipping in lye. The carrier may be of metal and particularly a wire lattice of nickel or iron. It may also be a solid electrolyte membrane, such as a disc of .beta.-Al.sub.2 O.sub.3.
