Abstract:

A simple and easy method with high accuracy has been introduced for the determination of hydrogen absorption properties of alloys, such as hydrogen absorption capacity , paressure-composition isotherms and thermodynamic parameters ΔH and ΔS.
The apparatus is described in details. The equilibrium data can be obtained under hydrogen pressure of 16—0.0001 MPa and in the range of temperature -196—+500 ℃.

Key words: Hydrogen-storage alloys, Hydrogen absorption and desorption, Determination of P-C-T
