Abstract
An improvement in the separator layer of an electrochemical heating element having two electrode layers, a separator layer of porous, absorbent material therebetween, and electrically conductive connector means extending through the electrode and separator layers. The improved device includes structural spacing means interposed between one of the electrode layers and at least a portion of the other electrode layer to limit compression of the separator layer material. In one embodiment, discrete mechanical spacers are placed immediately adjacent to the connector means. In another embodiment, a recessed surface portion is formed in one of the electrode layers and the adjacent separator layer has a mating portion on one side which is received into the recessed surface portion.
