Abstract: A system and method for diagnosing a fuel cell stack are provided. The method includes determining, by a controller, a time at which diagnosing the fuel cell stack is required based on a plurality of factors and driving a motor adjusted to a first efficiency value for a predetermined first reference time period based on the diagnosis determination. In addition, the controller is configured to drive the motor adjusted to a second efficiency value when the first reference time period has elapsed. A state of the fuel cell stack is then diagnosed based on a voltage variance of the fuel cell stack between driving the motor adjusted to the first efficiency value and second efficiency value.

Abstract: An electrical storage system includes a relay switching between an on state where an electrical storage device (10) is connected to a load and an off state where connection of the electrical storage device with the load is interrupted; a controller controlling an on-off state of the relay; and a current interruption circuit (60) interrupting energization of the electrical storage device. The current interruption circuit includes an alarm circuit (63) outputting an alarm signal indicating that any one electrical storage block is in an overcharged state by comparing a voltage value of each electrical storage block with a threshold; a latch circuit (64) retaining the alarm signal; a transistor (66) causing the relay to switch from the on state to the off state upon reception of an output signal of the latch circuit; and a power supply circuit (63d) generating electric power for operating the latch circuit using electric power of the electrical storage device.

Abstract: A device for detecting leakage of gas of a fuel cell vehicle includes a gas sensor configured to determine whether gas leaks based on a change in a temperature by a catalyst reaction and a vehicle control unit including a comparator configured to read a variation in temperature from the gas sensor, and configured to control a fuel cell vehicle. A power application state is maintained in the comparator in a power off state of the fuel cell vehicle. Power of the gas sensor is switched at regular periodic intervals. The comparator determines the variation in temperature measured by the gas sensor, and, when the variation in temperature exceeds a predetermined value, the power of the gas sensor is switched to normal power.
