SENSOR ELEMENT OF A GAS SENSOR FOR DETERMINING GAS COMPONENTS

摘要

The invention relates to a sensor element of a gas sensor for determining the concentration of hydrogen present in a gas mixture or hydrogen-containing gas components such as ammonia or hydrocarbons. Said sensor element comprises a measuring electrode (13) exposed to the gas mixture and at least one reference electrode (14), which is disposed on a proton-conducting solid electrolyte (11a). The solid electrolyte (11a) is composed of a pure-ceramic material.
