1. An electrochemical heating element comprising:
- an anode layer;
two separator layers of porous absorbent material, one on either side of said anode layer and each having an anode-adjacent surface and a cathode-adjacent surface, each of said anode-adjacent surfaces juxtaposed in contact with one side of said anode;
two cathode layers, one on either side of said anode layer and each having a surface juxtaposed in contact with one of said cathode-adjacent surfaces of said separator layers; and
a multiplicity of electrically-conductive connector means extending through said anode, separator and cathode layers to conduct an electric heating current between said anode layer and said cathode layers, including at least one connector extending only through said anode layer, one of said separator layers and the adjacent cathode layer.

Abstract
A complex electrochemical heat-generating element characterized by a two-surfaced anode layer, two separator layers of porous, absorbent material, one on either surface of the anode layer, two cathode layers, one in contact with each of the separator layers, and electrically conductive connectors extending through the cathode layers, separator layers and anode layer to conduct an electric heating current between the anode and cathode layers. Preferred embodiments relate to specific arrangements of connectors.
