Abstract: An object is to perform a purge at an appropriate timing. There is provided a fuel cell system mounted on a vehicle. The fuel cell system comprises a gas supplier that is configured to supply a purge gas into a fuel cell; and a controller that is configured to control the gas supplier and perform a purge with the purge as at a stop time of the vehicle. The controller obtains an ambient temperature in a driving state of the vehicle a plurality of times. In a case where an ambient temperature obtained last time among the ambient temperatures obtained in the driving state is lower than a predetermined reference value, the controller performs the purge with enhancing a purging capacity, compared with a case where the ambient temperature obtained last time is higher than the predetermined reference value.

Abstract: In a fuel cell monitoring device, a gas-diffusion resistance calculation section calculates a gas-diffusion resistance Rtotal indicating a difficulty of diffusing reaction gas to a catalyst layer in a fuel cell based on a gas reaction resistance Rct calculated by a resistance calculation section. A second diffusion resistance calculation section calculates a second diffusion resistance Rdry varying depending on a dried-up in the fuel cell based on a proton transfer resistance Rmem calculated by the resistance calculation section. A first diffusion resistance calculation section calculates a first diffusion resistance Rwet varying depending on a flooding in the fuel cell by subtracting the second diffusion resistance Rdry from the gas-diffusion resistance Rtotal. A water content calculation section calculates a water content of the fuel cell based on the first diffusion resistance. A recovery control section adjusts the water content in the fuel cell based on the calculated water content.

Abstract: Provided is a method for controlling a fuel cell vehicle capable of informing a user outside of the vehicle of the possibility that the fuel cell stops power generation and external power-feeding stops, whereby problems due to unexpected stopping of power feeding can be avoided. In a method for controlling a fuel cell vehicle 100 including an external power-feeding device 50, when it is determined that a state of a fuel cell exceeds a limiting point where deterioration of the fuel cell 20 or a failure of a driving device to supply fuel to the fuel cell 20 occurs during external power feeding, warning is issued to outside of the vehicle 10 before the fuel cell 20 stops power generation.

Abstract: When an actual output value is less than an output command value, a current command value is increased. When the actual output value is equal to or greater than the output command value, whether the actual output value is within a range of a dead band is determined. When the actual output value is outside the range of the dead band, the current command value is decreased. When the actual output value is within the range of the dead band, the current command value is maintained.

Abstract: There is provided a technique to suppress water from remaining in a fuel cell and auxiliary machines after a stop of operation of a fuel cell system. A fuel cell system 100 includes a controller 10, a fuel cell 20, a cathode gas supply discharge system 30 and an anode gas supply discharge circulation system 50. The controller 10 serves as a termination process controller 15 to control a termination process that is performed when operation of the fuel cell 20 is to be stopped. In the termination process, the termination process controller 15 performs a quick warm-up operation to quickly increase the temperature of the fuel cell 20, subsequently performs a standard warm-up operation that has a lower temperature rise rate of the fuel cell 20 than that in the quick warm-up operation, and then performs a purging process to purge the fuel cell 20.
