Abstract

An electrode for a cell or battery e.g. a porous oxygen electrode for a fuel cell, comprises a first layer of sintered metal particles e.g. Ag with a grain size of 4 to 15 microns and a second layer of unsintered metal particles e.g. Ag with a grain size of 0.3 to 1.5 microns which is joined to the first layer preferably by pressing. In a preferred method the first layer of Ag is compacted on to a grid and sintered at 600 DEG C. for 2 minutes. A layer of fine Ag powder is then compacted on to the sintered assembly at 5,000-10,000 p.s.i. to form an electrode with a porosity of 50% in the sintered layer and a porosity of 35% in the compacted layer.
