摘要： An oxidizing device and an oxidizing method for oxidizing a carbon-containing component in a gaseous mixture containing H2O and the carbon-containing component are disclosed having a proton conductive body and an electrode member placed on the proton conductive body. The electrode member has an anode electrode and a cathode electrode held in contact with each other and the proton conductive body has electric conductivity of 0.01 Scm−1 or more at a temperature of 400° C. or less. The anode electrode separates a proton (H+) from H2O at a boundary portion between the anode electrode and the proton conductive body to facilitate a reaction to introduce the proton into the proton conductive body. The cathode electrode facilitates a reduction reaction in the presence of the proton supplied from the proton conductive body at a boundary portion between the cathode electrode and the proton conductive body.

摘要： A gas sensor element has a first cell, a second cell, and a solid electrolyte layer having proton conductivity commonly used by the first cell and the second cell. The first cell has a first cathode and a first anode exposed to the target detection gas containing hydrogen atoms. The second cell has a second anode, a second cathode, and a shield layer with which the second anode is covered. A voltage is supplied to the first and second cells. A gas concentration of the target detection gas is calculated on the basis of a difference between a current of the first cell and a current of the second cell because the current in the first cell is a sum of proton conductivity current and an electron conductivity current. The current in the second cell is an electron conductive current only.

摘要： A gas concentration detecting system has a first cell generating electric current at first oxygen sensitivity, a second cell generating current at second oxygen sensitivity and a reference cell generating current at reference oxygen sensitivity. The cells have the same structure except that the second cell has a catalyst layer for removing hydrogen as from measured gas containing oxygen gas. The system determines first corrected current from current of the first cell exposed to measured gas, current of the first cell exposed to inspection gas containing oxygen gas at reference concentration and reference cell current of the reference cell exposed to inspection gas, determines second corrected current from current of the second cell exposed to measured gas, current of the second cell exposed to inspection gas and the reference cell current, and detects concentration of hydrogen gas in measured gas from the corrected currents.
