Abstract: The invention provides a hydrogen sensing device capable of preventing sensor sensitivity decreases. A hydrogen sensor 150 detects the hydrogen in an exhaust pipe and is installed in a divergent pipe DP. Flowing through the exhaust pipe is off-gas discharged from the fuel cell of a fuel cell vehicle. In order to decompose the siloxanes contained in the gas, a siloxane decomposing material 130 is placed upstream of the hydrogen sensor 150 inside the divergent pipe DP. Also, an SiO2 capturing material 140 is placed between the siloxane decomposing material 130 and the hydrogen sensor 150, so that the SiO2 capturing material can capture the SiO2 resulting from the decomposition of siloxanes by the siloxane decomposing material 130.

Abstract: An exhaust gas containing a perfluoride compound (PFC) and SiF4 is conducted into a silicon remover and brought into contact with water. A reaction water supplied from a water supplying piping and air supplied from an air supplying piping are mixed with the exhaust gas exhausted from the silicon remover. The exhaust gas containing water, air, and CF4 is heated at 700° C. by a heater. The exhaust gas containing PFC is conducted to a catalyst layer filled with an alumina group catalyst. The PFC is decomposed to HF and CO2 by the catalyst. The exhaust gas containing HF and CO2 at a high temperature exhausted from the catalyst layer is cooled in a cooling apparatus. Subsequently, the exhaust gas is conducted to an acidic gas removing apparatus to remove HF. In this way, the silicon component is removed from the exhaust gas before introducing the exhaust gas into the catalyst layer.

Abstract: A recombination apparatus is provided to an off-gas system of a boiling water nuclear plant. An off-gas system pipe connected to a condenser is connected to the recombination apparatus. A catalyst layer filled with a catalyst for recombining hydrogen and oxygen is disposed in the recombination apparatus. The recombination catalyst has a percentage of the number of Pt particles whose diameters are in a range from more than 1 nm to not more than 3 nm to the numbers of Pt particles whose diameters are in a range from more than 0 nm to not more than 20 nm, falling within a range from 20 to 100%. The condenser discharges gas containing an organosilicon compound (ex. D5), hydrogen, and oxygen, which is introduced to the recombination apparatus. Use of the above recombination catalyst can improve the performance of recombining hydrogen and oxygen more than conventional catalysts and the initial performance of the catalyst can be maintained for a longer period of time.

Abstract: An exhaust gas containing a perfluoride component (PFC) and SiIF4 is conducted into a silicon remover and brought into contact with water. A reaction water supplied from a water supplying piping and air supplied from an air supplying piping are mixed with the exhaust gas exhausted from the silicon remover.

The PFC is decomposed to HF and CO2 at a high temperature exhausted from the catalyst layer is cooled in a cooling apparatus. Subsequently, the exhaust gas is conducted to an acidic gas removing apparatus to remove HF. In this way, the silicon component is removed from the exhaust gas before introducing the exhaust gas into the catalyst layer. Therefore, the surface of the catalyst can be utilized effectively, and the decomposition reaction of the perfluoride compound can be improved.

Abstract: A catalytic exhaust gas decomposition spirals an exhaust gas containing therein a substance to be decomposed and a reactant gas, rectifies the spiral flow, and lets the substance to be decomposed react with the reactant gas after the spiral flow has been rectified. For rectifying the spiral flow of the exhaust gas and the reactant gas, a plate-like baffle wall has therein a through hole at a portion near its center. The spiral flow is allowed to pass through the through hole so as to be centralized temporarily. The spiral flow then passes through an enlarged section of a flow path downstream of the through hole before being introduced into the catalyst bed. The method helps minimize variations in gas velocity of the exhaust gas flowing into the catalyst bed, thereby allowing a desired decomposition rate to be obtained substantially consistently.
