    摘要： A fuel cell system includes a fuel cell stack, a warming up status detector, a warming up completion threshold setter, an informing device, an estimator, and a threshold changer. The warming up status detector is configured to detect a warming up status of the fuel cell stack. The informing device is configured to inform of completion of warming up when a value corresponding to a warming up status detected by the warming up status detector is equal to or higher than a threshold value set by the warming up completion threshold setter. The estimator is configured to estimate whether generated water is frozen in the fuel cell stack. The threshold changer is configured to change the threshold value set by the warming up completion threshold setter in accordance with a freezing state of the generated water in the fuel cell stack estimated by the estimator.

    摘要： A fuel cell system is provided which estimates a water content in a fuel cell based on a predetermined map using an integrated value of electric current generated by the fuel cell (ST4) before power generation is stopped (ST5). When a temperature of the fuel cell has fallen lower than a predetermined value (ST7) after the power generation is stopped (ST5), the fuel cell system determines a dry degree in the fuel cell (ST8) and an anode scavenging period (ST9) based on predetermined maps. Scavenging is performed in an anode in the fuel cell for the anode scavenging period (ST10).

    摘要： A fuel cell system includes a fuel cell, a fuel gas supply channel, a fuel off-gas discharge channel, an oxidant gas supply channel, an oxidant off-gas discharge channel, a first shut valve, a second shut valve, a shut valve controller, a temperature detector, a scavenging device, and an elapsed-time detector. The elapsed-time detector is configured to detect an elapsed time elapsed from a timing at which the fuel cell is shut down. The scavenging device scavenges the oxidant gas flow channel and the fuel gas flow channel in sequence if the elapsed time detected by the elapsed-time detector is within a first predetermined period of time. The scavenging device scavenges the fuel gas flow channel and the oxidant gas flow channel in sequence if the elapsed time detected by the elapsed-time detector is outside the first predetermined period of time.
