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 10−12 atm, or more preferably, of not less than 3×10−12 atm and of less than 10−2 atm.

摘要： A gas detector for use in, for example, measuring the concentration of flammable gas or detecting leakage of flammable gas. The gas detector has a gas detection element in which at least a heat-generating resistor and an insulation layer are laminated on a semiconductor substrate made of silicon while the insulation layer encloses the heat-generating resistor. The gas detector detects flammable gas on the basis of temperature and resistance of the heat-generating resistor which vary according to flammable gas. In the gas detection element, a protection layer in the form of a gas impermeable oxide film is provided on its outermost surface which comes into contact with an environmental atmosphere that contains flammable gas. Thus, alkali resistance is ensured. Since the protection layer is impermeable to gas, entry of impurities (organic silicon) contained in the environmental atmosphere into the protection layer is restrained, whereby output is stabilized and becomes accurate.
