A circuit breaker device is provided with a main contactor part that can switch between connection and disconnection of a battery and a circuit, and a circuit breaker () that can disconnect the battery. The circuit breaker () is provided with: a connector connection part () having a pair of connector circuit terminals () related to passing electricity through a coil for the main contactor part; a connector () that is attachable to and detachable from the connector connection part () and has a connector shorting terminal () that shorts the pair of connector circuit terminals () upon attachment to the connector connection part (); and a claw part () for restricting attachment of the connector () to the connector connection part ().

An end plate of a fuel cell stack is directly fixed to a humidifier. A resin pipe is attached to an oxygen-containing gas outlet of an end plate through a resin coupling pipe. The resin pipe includes one end having a large diameter and the other end having a small diameter. The other end is provided at an off gas supply channel of the humidifier. The off gas supply channel includes an inclined channel. The other end extends up to an end of the inclined channel where inclination of the inclined channel is started. An off gas ejection port is formed at the other end. The off gas ejection port is opened to the end of the inclined channel where inclination is started. Condensed water returned along the inclined channel flows from the off gas ejection port into the resin pipe.

A power supply apparatus includes a controller. If the controller detects that the internal resistance of a battery detected by an internal resistance detecting unit is relatively high, then the controller switches a first switch from an open state to a closed state using a first threshold value with respect to the voltage difference between a battery voltage and a system voltage, and if the controller detects that the internal resistance of the battery is relatively low, then the controller switches the first switch from the open state to the closed state using a second threshold value which is smaller than the first threshold value.
