Abstract:
A measuring arrangement for analyzing gas components in a gas mixture, comprising:at least one electrochemical solid electrolytic test cell including at least one cathode; a selective oxygen-ion-conductive layer covering the at least one cathode and including a mixed-conductive ceramic material, the selective oxygen-ion-conductive layer being exposed to the gas mixture and being configured to conduct oxygen therethrough only in the form of oxygen ions; and an electrically nonconductive layer separating the at least one cathode from the selective oxygen-ion-conductive layer, the electrically nonconductive layer including particular portions which are permeable to gas, the gas-permeable portions being configured to conduct the oxygen conducted through the selective oxygen-ion-conductive layer to the cathode; wherein the cathode is separated from the gas mixture by the selective oxygen-ion-conductive layer and the electrically nonconductive layer.
