    摘要: A gas sensor, comprises a substrate, a sensor unit including a functional layer and an electrode structure, and an electric heating and/or temperature measuring arrangement. An electrically conductive shielding structure is provided between the sensor unit and the electric heating arrangement in order to shield the measurement process at the sensor unit from interferences owing to the heating process, thereby reducing or preventing the effects of electrical fields caused by voltages applied to the heating arrangement from altering or disrupting the measurement process.

    摘要: The invention relates to a process for preparing a Pt/zeolite catalyst material, the material itself, and the use of the material in removing carbon monoxide from a gas. In a preferred embodiment, the invention relates to a process for preparing a Pt/zeolite catalyst material for the catalytic removal of CO in H.sub.2 -rich gas by means of selective CO oxidation and the use of such a catalyst material. The catalyst materials of the invention can be prepared by employing Pt(NH.sub.3).sub.4 Cl.sub.2.H.sub.2 O and a zeolite material. The resulting material can be used for the catalytic removal of CO from an H.sub.2 -rich outlet gas mixture from a methanol reforming reactor. The compositions and methods to produce catalytic materials result in products with high and prolonged catalyst activity. In particular, the methods and compositions of the invention can be used in removing CO from the hydrogen fed to fuel cells in electric vehicles having stored methanol fuel.
