| 摘要 |
<p>The invention relates to a sensor element (112) for proving a gas constituent in a gas mixture, comprising a first cell (120) and a second cell (156). The first cell (120) comprises a first electrode (130), a second electrode (142), and a first solid electrolyte (132) connecting the first electrode (130) and the second electrode (142). The second cell (156) comprises a third electrode (158), a fourth electrode (162), and a second solid electrolyte (170) connecting the third electrode (158) and the fourth electrode (162). The second electrode (142) is arranged in a first electrode cavity (148), and the fourth electrode (162) is arranged in a second electrode cavity (166). The first electrode cavity (148) can be impacted with gas from the measuring gas chamber (118), and the second electrode cavity (166) can be impacted with gas from the first electrode cavity (148). The first solid electrolyte (132) and the second solid electrolyte (170) each have a solid electrolyte material, wherein the solid electrolyte material is embedded in a carrier element (140) having a lower ionic conductivity than the solid electrolyte material.</p> |
