Abstract:
A gas sensor for partial pressure measurement of hydrogen and oxygen and a manufacturing method thereof are provided to measure the oxygen or hydrogen concentration in the environment unable to be exposed to atmosphere, and to simplify the manufacturing process. A gas sensor(100) for partial pressure measurement of hydrogen and oxygen comprises a solid electrolyte(110) including a closed internal space(130) which stores the air used as the reference electrode, a first electrode(120a) formed on one side of the solid electrolyte exterior, a second electrode(120b) formed in one side of the internal space of the solid electrolyte, and a lead wire(140) which is connected to the first electrode and the second electrode and exposed out of the solid electrolyte.
Abstract:
The present invention relates to a solid oxide fuel cell and a preparation method of an anode for the solid oxide fuel cell. The solid oxide fuel cell of the present invention includes a cathode, a compact cermet anode, and electrolyte in between the cathode and the anode. The compact cermet anode has resistance to sulfuration gas. Metal sulfide produced by the sulfuration gas when fossil fuel containing the sulfuration gas is supplied is reduced to prevent the decrease of properties of the anode and extend the lifetime of the fuel cell.
Abstract:
A method for producing and separating high-purity oxygen and hydrogen from fossil fuel without emission of carbon dioxide is provided to minimize use of fossil fuel, produce high-purity oxygen and hydrogen, prevent air pollution by preventing carbon dioxide from emitting into the atmosphere, and minimize heat loss by performing all processes at high temperatures. A method for producing and separating high-purity oxygen and hydrogen from fossil fuel without emission of carbon dioxide comprises: a first step(S1) of reforming a fossil fuel by a steam reforming process, a partial oxidation process, or an automatic thermal process to prepare a mixed gas containing hydrogen, carbon dioxide, carbon monoxide, and water vapor; a second step(S2) of separating hydrogen from the mixed gas by using a hydrogen separation membrane to prepare a carbon dioxide-rich gas; a third step(S3) of separating oxygen from the carbon dioxide-rich gas by using an oxygen separation membrane to prepare a carbon monoxide-rich gas; and a fourth step(S4) of reacting the carbon monoxide-rich gas with water to prepare a residual gas having the same composition as the mixed gas prepared in the first step, wherein the steps(S1,S2,S3,S4) are circulated by supplying the residual gas prepared in the fourth step into the mixed gas of the second step.
Abstract:
The present invention relates to a hydrogen sulfide tolerant cermet hydrogen separation membrane and a manufacturing method for the same. The hydrogen sulfide tolerant cermet hydrogen separation membrane includes: an oxygen ion conductor; and a hydrogen penetration metallic phase. The oxygen ion conductor forms a predetermined three-dimensional form, and the hydrogen penetration metallic phase is distributed at predetermined intervals so as to disperse hydrogen and oxygen at the same time. Generation of metal sulfides by the hydrogen sulfide of the hydrogen penetration metallic phase is thereby reduced and at the same time, a high penetration efficiency can be achieved.
