This document specifies the test method of hydrogen absorption/desorption kinetics properties for rare earth-based hydrogen storage alloy.
This document is applicable to the test of hydrogen absorption/desorption kinetics of rare earth-based hydrogen storage alloy by volume method (Siverts method). Test temperature: 25 ℃ to 300 ℃, environmental temperature : 23 ℃±3 ℃, test pressure: 0.001 MPa to 5 MPa. The test of rare earth-based hydrogen storage alloy with plateau pressure of 5 MPa to 10 MPa can refer to this document.
