Abstract
An electrochemical sensing element which includes at least one electrochemical cell having a planar solid electrolyte body and a pair of electrodes in contact with the planar solid electrolyte body, and which further includes at least one electrical heater layer which is located on one of opposite sides of the electrochemical cell. The heater layer comprises a heater member having a heat-generating portion in the form of a serpentine or sinuous strip to heat at least a portion of the electrochemical cell at which the electrodes are disposed. The serpentine strip is formed in zig-zag fashion to provide a heating region in which the heat-generating portion is accommodated. The heat-generating portion has a larger cross sectional area at its central parts located in a central portion of the heating region, than at its peripheral parts located adjacent to the periphery of the heating region.
