“…The SDC sensors presented in this study are close to several new type of electrochemical sensors which are currently developed by several groups, especially for automotive exhaust applications [9,10]. In regard of conventional electrochemical sensors with a physical separation between the two electrodes, these sensors have their two electrodes in the same atmosphere.…”

International audienceAn original sensor has been studied in order to detect low CO concentration in h2-rich atmosphere for pem (protonic exchange membrane) fuel cell applications. The SCD (samarium doped ceria) sensor is a potentiometric sensor working with an electrode dissymmetry Au/Pt. The originality of this sensor is mainly working with the two electrodes in the same atmosphere without a reference cell. The Δ (emf) response, defined by the difference between the emf (electromotive force) value under carrier gas and the emf value under CO, is correlated with the CO concentration. Experiments have been carried out on a laboratory testing bench, either with a large measurement cell equipped with a hot plate and two mobile gold points as electrical contacts or in a small cell with self-heated sensors supplied with a platinum heater on the reverse side of the substrate. Responses to low CO concentrations (0-4000 ppm v/v) in H2-rich gases (5% v/v) varies between 25 and 100 mV, but saturation is observed beyond 400 ppm v/v of CO. In wet atmosphere, the sensitivity is partially reduced but the sensor response remains perfectly usable. At the moment no satisfying model can be used to explain the experimental results. Nevertheless, the performances of these SCD sensors appear sufficiently good to satisfy the fuel cell application

“…As a response to these requirements, solid-state NO x sensors based on 8% yttria stabilized zirconia (YSZ) solid electrolyte and metal oxide sensing electrodes have been developed. The sensors can be divided into impendancemetric-type [1][2][3][4][5][6][7][8], amperometric-type [9] and mixed-potential [10]. Among them, impendancemetric-type gas sensors are a kind of new sensors that are able to monitor total NO x in the exhaust gas under the presence of oxygen.…”
