Abstract
A hydrogen supply method including a (1-1)th fluid circulation operation in which a first fluid sequentially circulates through a first fluid circulation line including a first heat exchanger in which the first fluid and an external fluid exchange heat therebetween, a first flow rate control member that controls flow of the first fluid, a compressor, the first flow rate control member, a second heat exchanger, and an expansion member. The hydrogen supply method further includes a (2-1)th fluid circulation operation in which a second fluid circulates through a second fluid circulation line through which the second fluid circulates and exchanges heat with the first fluid in the second heat exchanger.

A hydrogen storage thermal management system comprising:
- a first fluid circulation device including a first fluid circulation line through which a first fluid circulates;
- and
- a second fluid circulation device including a second fluid circulation line through which a second fluid circulates,
- wherein the first fluid circulation device comprises:
- a first heat exchanger by which the first fluid and an external fluid exchange heat therebetween;
- a four-way valve connected to the first heat exchanger through the first fluid circulation line and configured to control flow of the first fluid;
- a compressor, connected to the four-way valve through the first fluid circulation line, configured to compress the first fluid;
- a second heat exchanger connected to the four-way valve through the first fluid circulation line;
- an expansion valve, connected to the second heat exchanger through the first fluid circulation line, configured to expand the first fluid,
- wherein the second fluid circulation line is connected to the second heat exchanger so that the first fluid and the second fluid exchange heat therebetween in the second heat exchanger,
- wherein the second fluid circulation device comprises:
- a pump, connected to the second heat exchanger through the second fluid circulation line, configured to pump the second fluid;
