PROBLEM TO BE SOLVED: To provide a hydrogen storage/discharge device and a hydrogen storage/discharge method capable of efficiently storing and discharging hydrogen in a wide temperature range.SOLUTION: A hydrogen storage/discharge device of the invention comprises: a tank in which a hydrogen storage alloy is filled for storing/discharging hydrogen; and a heat medium circulation part attached to the tank and in which a heat medium for heating/cooling the hydrogen storage alloy can circulate, in which two kinds or more of the hydrogen storage alloy different in hydrogen equilibrium pressure are blended and filled in the tank. The hydrogen storage alloy preferably may be powder. The heat medium preferably may use air. The hydrogen equilibrium pressure of the hydrogen storage alloy at 25°C preferably may range from 0.1 MPa to 1 MPa. The hydrogen emission speed per unit mass of the whole hydrogen storage alloy preferably may range from 0.01 NL/min/kg to 1 NL/min/kg.SELECTED DRAWING: Figure 1 |
