ABSTRACT:
A heating device is taught which includes a subdivided electrochemical cell comprising subdivided metal pieces which serve as the anode and conductive cathode layers coated on the anode pieces. When such coated pieces are enveloped in a liquid electrolyte, heat is generated by electrochemical-cell reactions; and the reactions and accompanying production of heat are accelerated by the direct electrical contact between the anode pieces and cathode layers. The cathode layers can be coated on the anode pieces either prior to assembly of the heating device, or in situ after the device has been activated. In the latter case, plating is accomplished through the presence in the liquid electrolyte of a plating salt that reacts with the metal anode pieces and produces an electroless deposition on the pieces.
