An electrochemical element to be used for, for example, an oxygen detector or controller, comprises en electrochemical cell having a solid electrolyte 1 and at least a pair of porous electrodes 2, 3 in contact therewith and a heater contacting the electrolyte 1 directly or via a high resistance layer 6 and being insulated from said electrodes 2, 3. To prevent or minimize leakage current from the heater to the cell, an electron conductor embedded in a solid electrolyte is provided between the electrochemical cell and the heater. |
