[0036] In the present embodiment, a reducing gas sensor 100 (hereinafter simply referred to as "sensor 100") configured to detect reducing gas using a palladium metal complex (hereinafter referred to as "Pd complex") will be described with reference to FIG. 1 . FIG. 1 is a schematic diagram showing the configuration of a sensor 100 .
[0037] Figure 1A is a schematic plan view of the sensor 100 according to the present embodiment. The sensor 100 includes a substrate 10 , a pair of electrodes 11 , a reaction layer (gas reaction part) 12 , a power source 13 , and a measurement unit (detection circuit) 14 .
[0038] The material of the substrate 10 may be, for example, glass, quartz or silicon.
[0039] The pair of electrodes 11 are disposed on the substrate surface of the substrate 10 so as to face each other. The material of the counter electrode 11 is a conductor, such as metal or organic conductive material. Specific examples include gold (Au), aluminum (Al), and ITO.

[0104] In this embodiment, reference will be made to image 3 The configuration of the sensor 300 for detecting reducing gas will be described. image 3 is a schematic cross-sectional view showing the configuration of the sensor 300 according to the present embodiment. The sensor 300 includes a substrate 30 , a pair of electrodes 31 and a gas reaction part 32 . The substrate 30 may be the same as the substrate 10 in the first embodiment.
[0105] The gas reaction part 32 is a layer provided on the substrate surface of the substrate 30 . The gas reaction portion 32 is provided to be sandwiched between the pair of electrodes 31 in a direction perpendicular to the substrate surface. In addition, in this embodiment, the gas reaction part 32 is a reaction layer containing the Pd complex represented by General formula (1). Therefore, as in the first embodiment, a power source and a measurement unit (not shown) are connected to the pair of electrodes 31, the conductivity of the g...

[0109] In this embodiment, a mobile body including the sensor 100, 200, or 300 according to the first embodiment or the second embodiment will be described. In this embodiment, reference will be made to Figure 4 A fuel cell vehicle 400 as a mobile body will be described. Figure 4 is a schematic diagram showing an example of the configuration of the fuel cell vehicle 400 .
[0110] The fuel cell vehicle 400 includes a vehicle compartment 41 , hydrogen sensors 42 and 44 , a hydrogen fuel tank (hydrogen tank) 43 , a fuel cell 45 and a motor 46 .
[0111] The hydrogen fuel tank 43 and the fuel cell 43 are each provided in a space separate from the vehicle interior 41 . The fuel cell 43 generates electric power when hydrogen gas is supplied from the hydrogen fuel tank 43 and oxygen gas is supplied. Electric power generated by the fuel cell 43 is transmitted to the motor 46 of the fuel cell vehicle 400 and used as a driving force for driving the fuel cell vehicle 400 . As the ...
