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.

Abstract: Hydrogen-producing fuel cell systems and methods of operating the same. The methods include initiating supply of a stored hydrogen stream, which includes stored hydrogen gas, to a fuel cell stack. Prior to the initiating, the stored hydrogen gas is stored in a low-pressure hydrogen storage tank at a hydrogen storage pressure. The methods also include generating an electrical power output from the stored hydrogen gas with the fuel cell stack. The methods further include, during a supply time interval that is subsequent to the initiating, monitoring a hydrogen supply variable that is indicative of flow of the stored hydrogen stream to the fuel cell stack. The methods also include detecting a change in the hydrogen supply variable and responding to the detecting. The systems include a controller that is programmed to perform the methods.
