摘要： 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.

摘要： The present invention provides a catalytic combustion type hydrogen gas sensor of a simple structure, which is capable of inhibiting the degradation of the sensitivity thereof over a long period of time even in the presence of a silicon compound being a catalyst poison. This hydrogen gas sensor is equipped with a detection element 1 having a sensing part 2 and a silicon trapping body 3. The sensing part 2 has a function of being heated by Joule heat generated by energization of the sensing part 2, a function of combusting hydrogen gas while being heated, and a function of outputting a change in electrical resistance of the sensing part 2 indicative of hydrogen gas concentration, the change in electrical resistance being caused by an increase in temperature of the sensing part 2 caused by the combustion heat of the hydrogen gas. The silicon trapping body 3 covering the sensing part 2 contains a silicon-trapping material that functions to trap a silicon compound from a gaseous matter passing through the silicon trapping body 3.

摘要： The hydrogen gas sensor is a catalytic combustion hydrogen gas sensor with a detection element 1, and is characterized by comprising a measuring circuit configured to selectively provide a normal voltage mode for applying a normal voltage to the detection element 1 and a high voltage mode for applying a high voltage higher than said normal voltage to said detection element 1. Thereby, upon energization of the hydrogen gas sensor, the detection element 1 can be first applied the high voltage to be rapidly heated to raise a temperature of the detection element 1 immediately.
