Abstract: Provided is a gas sensor that needs no temperature sensor for detecting a temperature of a heater for preventing dew condensation. The gas sensor comprises a hydrogen sensor 1 including: an element housing 13 having a detection chamber 13a to which hydrogen is introduced; a detection element 31 arranged in the detection chamber 13a and detecting hydrogen; a heater 21 for heating the detection chamber 13a by heat generation via passing an electric current through the heater 21, a resistance value of the heater 21 being changed corresponding to a temperature of the detection chamber 13a; and a microcomputer 51 and a heater operation circuit 52 for controlling the heater 21. Herein, the microcomputer 51 controls a temperature of the detection chamber 13a by adjusting the electric current passing through the heater 21 based on the resistance value of the heater 21.

Abstract: Provided is a catalytic combustion typed gas sensor of detecting a combustible gas having a concentration equal to or more than a predetermined value based on a raised electric resistance. Herein, combustion heat generated when a combustible gas contacts to a catalytic metal (or detection element) heated by passing electric current therethrough raises a temperature and electric resistance of the catalytic metal. The electric current is made to pass through the catalytic metal such that the temperature of the catalytic metal becomes a standby temperature which is calculated by subtracting the raised temperature portion from a desorption temperature. The combustion heat is generated when the combustible gas contacts to the catalytic metal. Note the catalytic metal adsorbs a silicone compound via a silicon (Si) poisoning process and then desorbs the resulting adsorbed silicone compound at the desorption temperature. The desorption temperature is set in the range over 350° C. to 600° C.

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.
