Measuring P-C-T curves of storing hydrogen material-hydrogen systems by changing temperature method

The principle, experimental apparatus and detailed measuring steps by changing temperature method to measure the P-C-T curves of storing hydrogen material-hydrogen systems with equilibrium pressures at room temperature in the range of 10-3 - 10-5 Pa, whose activities may go down easily, are described. Operating feasibility of the method is tested. The advantages and defects of the method are analyzed primarily, too
