Patent number: 11916266Abstract: 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.Type: GrantFiled: March 25, 2021Date of Patent: February 27, 2024Assignee: ENEOS CORPORATIONInventors: Akihiko Fukunaga, Toshio Tezuka, Tadashi Seike, Hirofumi Nishio, Daisaku Tateishi
