Abstract: A hydrogen production supply system that produces hydrogen gas to be supplied to a hydrogen storage tank, the hydrogen production supply system including a control circuit configured to control an operation load ratio of the hydrogen production apparatus to a predetermined operation load ratio, to increase the operation load ratio of the hydrogen production apparatus to a first operation load ratio larger than the predetermined operation load ratio at first timing, and to decrease the operation load ratio of the hydrogen production apparatus to the predetermined operation load ratio from the first load operation ratio at second timing, wherein an increase in the operation load ratio at the first timing takes precedence over a decrease in the operation load ratio at the second timing.

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.
