    • A failure detection apparatus for a resolver outputting a sine signal indicative of sin θ and a cosine signal indicative of cos θ according to a rotational angle θ of a rotator, includes an inspection value calculating section configured to calculate an inspection value based on at least one of the sine signal and the cosine signal; a failure detecting section configured to judge whether the resolver is in a failure state or not on the basis of the inspection value; a counting section configured to gradually increase a count value with a lapse of time when the failure detecting section is determining that the resolver is in the failure state, and configured to gradually decrease the count value with a lapse of time when the failure detecting section is determining that the resolver is not in the failure state; and a failure deciding section configured to finally decide that the resolver has caused the failure on the basis of the count value.

    • A fuel cell system (100) includes: a circulation pump (50) provided on a fuel gas circulation channel (27) so as to circulate a fuel gas; a pump temperature detection portion (420) that detects a temperature of the circulation pump (50); a warmup portion that warms up the circulation pump; a pump control portion (410) that drives the circulation pump; and a breakdown determination portion (450) that determines whether the circulation pump has broken. At the start of the fuel cell system, if the pump temperature detected by the pump temperature detection portion (420) is below the melting point of water, the warmup portion warms the circulation pump, and the pump control portion (410) drives the circulation pump (50). If the pump temperature is higher than or equal to the melting point of water and the rotation speed of the circulation pump (50) is less than a predetermined speed, the breakdown determination portion (450) determines that the circulation pump (50) has broken.
    • 燃料电池系统(100)包括:设置在燃料气体循环通道(27)上以使燃料气体循环的循环泵(50); 检测循环泵(50)的温度的泵温度检测部(420)。 加热循环泵的预热部分; 驱动循环泵的泵控制部(410); 以及判定循环泵是否破裂的击穿判定部(450)。 在燃料电池系统的启动时,如果由泵温度检测部(420)检测到的泵温度低于水的熔点,则预热部加热循环泵,并且泵控制部(410)驱动循环 泵(50)。 如果泵温度高于或等于水的熔点并且循环泵(50)的转速小于预定速度,则故障确定部分(450)确定循环泵(50)已经断裂 。
