HYDROGEN RECYCLING DEVICE AND HYDROGEN RECYCLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen recycling device and a hydrogen recycling method capable of preventing a drop in hydrogen storing efficiency by preventing attachment of water to a hydrogen storage alloy.

SOLUTION: The hydrogen recycling device 6 is equipped with a purged hydrogen piping 11 through which hydrogen gas purged from the anode side of a fuel cell stack 4 is passed, and a recovering tank 62 installed in the the purged hydrogen piping 11. A water adsorbent 62b for adsorbing moisture contained in hydrogen gas in addition to the hydrogen storage alloy 62a for storing hydrogen gas is contained in the recovering tank 62.
