Abstract (en)
[origin: WO03036281A2] A gas sensor for the determination of at least one physical parameter of a gas, in particular the exhaust gases of an internal combustion engine, is disclosed, comprising a sensor element (10, 110) with an electrochemical cell. The electrochemical cell comprises a first solid electrolyte body (21, 121), on which a first electrode (41, 141, 241) and a second electrode (42, 142) are mounted. The first and the second electrodes (41, 141, 241, 42, 142) are electrically connected through the first solid electrolyte body (21, 121). The first electrode (41, 141, 241) is in contact with the gas. The surface of the first electrode (41, 141, 241) is smaller than the surface of the second electrode (42, 142).
