Abstract: A power supply system includes a power converter and a controller. The power converter includes a positive electrode line, a negative electrode line, first and second switching elements, and a magnetic coupling reactor. The magnetic coupling reactor includes a reactor core, and first and second coils. The second coil is wound around a second outer leg of the reactor core and is magnetically differentially connected to the first coil. The controller is configured to execute a first discharge process and a second discharge process, which is executed after the first discharge process, to discharge electric charge remaining in the fuel cell. The controller is configured to, in the first discharge process, turn on the first switching element in a state where the second switching element is off, and, in the second discharge process, turn on the second switching element in a state where the first switching element is on.

Abstract: An operation method is provided for a hydrogen production apparatus that is disposed in a hydrogen station and produces hydrogen gas to be supplied to a fuel cell vehicle (FCV) arriving at the hydrogen station. The operation method includes starting up a hydrogen production apparatus up to a first operation load ratio preset for a rated operation. The operation method includes increasing an operation load of the hydrogen production apparatus to a second operation load ratio, which is larger than the first operation load ratio, at first timing associated with an arrival of the FCV, and decreasing the operation load of the hydrogen production apparatus to a third operation load ratio, which is smaller than the second operation load ratio, at second timing associated with a completion of hydrogen filling into the FCV.
