Résumé
We present a new mixed potential gas sensor configuration based on a stack structure fabricated by means of the screen-printing technique. The use of this method allows the implementation of a very compact planar device in an easy, fast and highly economical way. The proposed structure is tested using yttria-stabilized zirconia as electrolyte, and strontium-doped lanthanum manganite and gold as electrodes. Excellent performance and fast response time to CO polluting gas are corroborated at relatively low temperature. No cross-sensitivity to NO2 is observed. Besides, the device signal remains remarkably stable in long-term experiments.
