PURPOSE:To reduce the size and weight of a titled element with virtually no losses of heating energy by providing heating elements via insulation layers into a solid electrolyte which is sandwiched between a pair of electrodes and exhibits which is sandwiched between pair of electrodes and exhibits permselectivity for specific ions when heated. CONSTITUTION:A gas A is filled or flowed in a pipe 4 and a gas B in a pipe 5. The gaseous oxygen contained in both gases A, B passes through respectively porous electrodes 2 and 2' and contacts the surface of, for example, stabilized zirconia 1. On the other hand, electric current is flowed to the heating elements 9 embedded into the solid electrolyte such as the zirconia 1 to evolve heat, thereby heating the zirconia 1 to about >=800 deg.C. Then, the zirconia 1 exhibits conductivity or permeability for oxygen ions. Since this element does not require any high-temp. thermostat and electric furnace as well as their heat insulators, it is reduced of size and weight. |
