Abstract
The invention concerns a method for the manufacture of an electrode material containing silver-coated tungsten carbide for electrochemical cells, particularly fuel cells and storage cells. Silver is precipitated on finely-divided tungsten carbide particles by reduction of a silver salt, and the tungsten carbide particles are thereby joined to form particles of larger grain size.
