Abstract: A cathode compartment is defined by a pair of filter walls between which a cathode or electrolyzing ionic solution of a metal is received. The electrolysis is forced through this compartment and the current density against an anode outside the compartment is sufficiently high to cause at least some of the metal in solution to deposit as a powder which accumulates in the cathode compartment and augments the effective surface area of the cathode.
