An electrochemical cell is described comprising: an electrolyte; integral cell electrode/heater means contacting the electrolyte and adapted for heating at least a portion of the electrolyte to an elevated temperature for ionic conduction operation; a pair of lead means each extending from a different location on the integral cell electrode/heater means for coupling the integral cell electrode/heater means in a circuit across an electric current source; a second cell electrode means separately contacting the electrolyte and adapted for developing an ionic conduction across the heated electrolyte and a related emf with the integral cell electrode/heater. A method is described of operating an apparatus for sensing a particular gaseous substance, the apparatus comprising an electrochemical cell heated to an elevated temperature for ionic conduction operation and circuit means for responding to ionic emf developed by the electrochemical cell.
