Title:
HYDROGEN ABSORBING ALLOY, HYDROGEN ABSORBING METHOD, AND HYDROGEN DESORPTION METHOD
Document Type and Number:
Japanese Patent JP2021138989
Kind Code:
A
Abstract:
To provide: a hydrogen absorbing alloy that can enhance an effective amount of absorbed hydrogen within a hydrogen pressure range from 0.1 MPa(abs) to 1.1 MPa(abs) inclusive; and a hydrogen absorbing method and a hydrogen desorption method that employ the alloy.SOLUTION: A hydrogen absorbing alloy absorbs hydrogen when the temperature is 40°C or less and the hydrogen pressure is 1.1 MPa(abs) or less, and desorbs hydrogen when the temperature is 50°C or more and the hydrogen pressure is from 0.1 MPa(abs) to 1.1 MPa(abs) inclusive, and has composition represented by general formula TiFexMnyNbz (0.761≤x≤0.837, 0.101≤y≤0.205, and 0.008≤z≤0.091).SELECTED DRAWING: None
