FIELD: precious metallurgy.
SUBSTANCE: device comprises anode and cathode made of layers of graphitized fleecy jersey fabric and metallic grid interposed between the layers of the graphitized fleecy jersey fabric. The metallic grid is made of layers of flat members and volume-reinforced members interposed between them. The volume-reinforced members are triangle, rectangular, trapezoidal, sinusoidal or round in cross-section.
EFFECT: enhanced efficiency.
