Assignee: KIA CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  B  Y | IPC B  H

Claim 4:
5. The fuel cell-battery system of claim 1, wherein the fuel cell module further includes:
a hydrogen temperature acquisition device configured to obtain temperature of the hydrogen passing through the external heat exchanger; and
a fuel cell controller electrically connected with the hydrogen temperature acquisition device,
wherein the hydrogen tank includes a hydrogen reservoir in which the hydrogen is stored and an internal heat exchanger through which the hydrogen reservoir and an introduced material exchange heat with each other, and
wherein the fuel cell controller:
returns the hydrogen to the internal heat exchanger through the return line to cool the hydrogen, when the obtained hydrogen temperature is higher than or equal to an upper limit of a target hydrogen temperature range; and
returns the hydrogen to the external heat exchanger through the return line to heat the hydrogen, when the obtained hydrogen temperature is lower than or equal to a lower limit of the target hydrogen temperature range.
