| titleOfInvention | Catalytic Degradation Sensor |
| abstract | Catalytic degradation sensor comprising an ion conductive solid electrolyte layer, two electrodes each formed on both sides of the solid electrolyte layer, and two gas diffusion control barrier layers respectively stacked on both sides of the solid electrolyte layer covering each electrode The catalyst deterioration detection sensor according to the present invention is characterized in that the solid electrolyte layer and the gas diffusion control barrier layer both include stabilized zirconia and inorganic materials. It is possible to detect the limiting current value which is proportional to the deviation from the theoretical performance ratio without having to provide a separate driving circuit to change the direction of the pumping current. Because diffusion control barrier layers are made using the same material Becomes to the manufacturing process of the sensor is simple, innovative are the same thermal expansion coefficient of each layer constituting the sensor is excellent in thermal shock resistance. In addition, the catalytic degradation sensor according to the present invention has an advantage that it is possible to obtain an equivalent limit current value in the fuel lean region or the fuel excess region by adjusting the electrode area or the thickness of the gas diffusion control barrier layer. |
