HYDROGEN SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2023151906
Kind Code:
A
Abstract:
To provide a hydrogen supply system with improved hydrogen production efficiency.SOLUTION: A hydrogen supply system 10 comprises: a water electrolysis system 11 having a water electrolysis device 18 and for generating hydrogen 41 by electrolytically decomposing water 40 and supplying the hydrogen 41 to a hydrogen utilization device 19; a hydrogen recovery system 12 having a hydrogen separation membrane 20 for recovering the hydrogen 41 contained in an exhaust gas 42 discharged from the hydrogen utilization device 19 from the exhaust gas 42 and supplying a recovery hydrogen gas 43 recovered by the hydrogen separation membrane 20 to the hydrogen utilization device 19; and heaters 13, 14 and 36 provided in at least one of the water electrolysis system 11 and the hydrogen supply system 12. A breed gas 44 remaining after the recovery hydrogen gas 43 is recovered by the hydrogen separation membrane 20 contains the hydrogen 41. The breed gas 44 is a heat energy source of the heaters 13, 14, and 36.SELECTED DRAWING: Figure 1
