Sensor element with improved poison resistance |
| abstract |
The invention relates to a sensor element (110) for determining at least one physical property of a gas in at least one measurement gas space (112), in particular for determining an oxygen concentration in the exhaust gas of an internal combustion engine. The sensor element (110) comprises at least one first electrode (116) and at least one second electrode (118) and at least one solid electrolyte (120) connecting the first electrode (116) and the second electrode (118). The second electrode (118) can be acted upon with gas from the measuring gas space (112) via at least one connection (124). The connection (124) has at least one diffusion barrier (132). The diffusion barrier (132) has at least one first region (144) and at least one second region (146), wherein the second region (146) lies between the first region (144). and the second electrode (118). The first region (144) has a smaller pore size than the second region (146). |
