摘要： A fuel cell system for a mobile body includes a fuel cell, an oxidant gas supply system, and a controller. The oxidant gas supply system includes an air compressor. The air compressor includes a rotor, an air bearing, and a housing. The controller includes a movement speed detector configured to measure a movement speed of the mobile body, and an acceleration detector configured to predict an acceleration to be applied to the mobile body. The controller is configured to determine whether the acceleration predicted by the acceleration detector is equal to or higher than a predetermined acceleration threshold, and control a rotation speed of the air compressor to be equal to or higher than a predetermined first rotation speed when determination is made that the acceleration predicted by the acceleration detector is equal to or higher than the acceleration threshold.

摘要： A pair of electrodes; and a reactive layer electrically in contact with the pair of electrodes are included. The reactive layer includes a palladium metal complex represented by General formula (1) below, and a change in electric conductivity between the pair of electrodes is measured to detect a reducing gas. The change is caused by an irreversible redox reaction between the palladium metal complex and the reducing gas. where each of OR1 to OR4 is a monodentate ligand, or forms a polydentate ligand by bonding to each other, or forms a bridging ligand by bonding to a palladium atom different from the palladium atom in General formula (1), and R1 to R4 each have one or more carbons and may be the same or different.

摘要： A cell monitor connector is inserted with a first surface following a guide portion. When the cell monitor connector is further inserted, the cell monitor connector makes contact with a projection portion. In a state where the attachment is completed, the projection portion is elastically deformed so as to press a second surface. Due to this force, the cell monitor connector is held such that it is sandwiched between the projection portion and the guide portion.

摘要： A fuel cell system comprises: a fuel gas supplier: an air supplier; an air flow rate acquirer that obtains a flow rate of the air that is supplied to a fuel cell; a voltage acquirer that obtains an output voltage of the fuel cell; and a controller. At the time of starting the fuel cell system, the controller controls the fuel gas supplier to supply a fuel gas to the fuel cell for a first time period. After elapse of the first time period, the controller controls the air supplier to start supply of the air. The controller calculates an integrated value of the flow rate for a second time period after the supply of the air is started. When the integrated value becomes greater than a predetermined amount and the output voltage is less than a predetermined voltage, the controller determines that the fuel cell system has an abnormality.
