摘要： A hydrogen sensor which may be employed in an overcharge/overdischarge detector for a battery and a hydrogen leakage detector for a fuel cell is provided. The hydrogen sensor includes a sensor element and a diffused resistor member. The gas to be measured passes through the diffused resistor member and reaches the sensor element. The sensor element outputs a signal indicative of the concentration of hydrogen contained in the gas as a function of a decrease in concentration of oxygen contained in the gas arising from reaction of the hydrogen on the oxygen. The diffused resistor member is so designed that speeds of diffusion of the hydrogen and the oxygen when passing through the diffused resistor member are different from each other for increasing the sensitivity of measurement of the concentration of hydrogen.

摘要： A fault detecting apparatus for a gas concentration sensor is provided. The apparatus includes a storage device and a fault detecting circuit. The storage device stores therein fault detectable conditions in which preselected different types of faults of the gas concentration sensor are allowed to be detected, respectively. The fault detecting circuit works to detect a selected one of the faults stored in said storage device. When one of the fault detectable conditions is encountered during operation of the gas concentration sensor, the fault detecting circuit initiates detection of a corresponding one of the faults based on an output of the gas concentration sensor, thereby enabling the fault detecting circuit to identify the type of one of the faults to be detected correctly.
