1. Dimensionally stable anode for electrochemical reactions characterized in that it comprises an electroconducting body impermeable to aqueous electrolytes and to gases constituted by a thermoformed mixture of graphite particles and inert thermoplastic resin powders having on at least one side thereof an electrocatalytic layer impermeable to aqueous electrolytes and gases consisting of a mixture of inert resin and particles of an oxide of at least one of the metals belonging to the group of ruthenium, iridium, platinum, palladium, rhodium, manganese, cobalt, lead, iron, tin, and nickel, the inert thermoplastic resin of the electroconducting layer forming a homogeneous matrix through the cross-section of the anode whereby the graphite particles of the electroconducting body and the particles of an oxide of the electrocatalytic layer are each fused in a continuous resin matrix, and wherein said thermoplastic resin is capable of being fused to produce a substantially impervious body.
