Device for detecting characteristic of gas in measurement gas compartment, particularly for use in internal combustion engine or fuel cell, has sensor element with two electrodes and solid electrolyte connecting electrodes

摘要

The device (110) has a sensor element (116) with two electrodes and a solid electrolyte (120) connecting the electrodes. A grid (122) partially encloses the sensor element. The grid is arranged to prevent propagation of an ignition of electrolytic gas on the sensor element. The sensor element is arranged to detect a proportion of hydrogen or oxygen in the gas. The grid is completely or partially formed of copper. An independent claim is included for a method for operating gas characteristic detecting device.
