  • Gas Sensor, Fuel Supply System Using the Same, and Method of Using Gas Sensor
    Publication number: 20090050493
    Abstract: A gas sensor has a gas diffusion barrier that supports therein a catalyst that catalyzes a reaction between combustible components and oxygen; a solid electrolyte having oxide ion conductivity; and electrodes formed on opposite surfaces of the solid electrolyte. The electrode is formed in a region into which ambient gas diffuses at a rate limited by the gas diffusion barrier. The electrode also catalyzes the reaction between combustible gas and oxygen. The electrode is formed in a region into which atmosphere is introduced.
