    摘要: A hydrogen gas sensor is configured such that an O-ring 21 is disposed within a measurement chamber 11a in order to seal against a first support element 9a and against a proton conduction layer 1. This O-ring 21 assumes the form of a rectangular frame that surrounds a first electrode 3, and a substantially circular cross section, and is elastic, heat resistant, and durable. A first metal plate 23a and a second metal plate 23b are disposed from the outside on opposite support elements 9a and 9b, respectively. The hydrogen gas sensor of the present embodiment has a pair of right-hand and left-hand through-holes 29 formed therein so as to extend along the thickness direction thereof. Bolts 31 are inserted into the corresponding through-holes 29. By fastening the metal plates 23a and 23b from the outside by means of the bolts 31 and nuts 33, the opposite support elements 9a and 9b are fastened, thereby clamping the entire hydrogen sensor in a unitary condition.

    摘要: A hydrogen sensor includes a first electrode 3 and a second electrode 4 provided in contact with a proton conduction layer 2; a gas diffusion controlling portion 6 provided between a measurement gas atmosphere and the first electrode 3; and a support element (1a, 1b) for supporting the proton conduction layer 6, the first electrode 3, the second electrode 4, and the gas diffusion controlling portion 6. Hydrogen contained in a measurement gas introduced via the gas diffusion controlling portion 6 is dissociated, decomposed, or reacted by applying a voltage between the first electrode 3 and the second electrode 4 to thereby generate protons. Hydrogen concentration is obtained on the basis of a limiting current generated as a result of the generated protons being pumped out via the proton conduction layer 2 from the first electrode 3 side of the proton conduction layer to the second electrode 4 side of the proton conduction layer. Hydrogen concentration on the first electrode 2 is controlled to a partial pressure of not less than 10null12 atm, or more preferably, of not less than 3null10null12 atm and of less than 10null2 atm.

    摘要: A hydrogen gas sensor including a first electrode 3 provided on one surface of a proton conduction layer 1; a second electrode 5 provided on the other surface of the proton conduction layer 1 in opposition to the first electrode 3; and these components are supported in a support element including a first support element 9a and a second support element 9b. A conductive, elastic element 23 is disposed between a first lead portion 10a and a first electrode 3 in contact with the first lead portion 10a and the first electrode 3. The conductive, elastic element 23 is an electrically conductive, elastic sheetlike element made of metal, and has a pair of right-hand and left-hand through-holes 25 formed therein at a central portion thereof. The conductive, elastic element 23 is held between the first lead portion 10a and the first electrode 3 while being pressed inward by a first support element 9a. Thus, the first electrode 3 comes in close contact with the proton conduction layer 1, whereby electrical connection is established therebetween.
