摘要

A Round Robin Test exercise on magnesium hydride (MgH_2) was performed by 14 labora-tories with the aim to compare experimental isothermal data such PCI curves, kinetics curves and formation enthalpies together with a basic statistical evaluation of the results. The full hydrogen capacity was found to vary in the range 5.1-6.4 wt.% at 280 ℃ (553 K) and in the range 5.3-6.6 wt.% at 320 ℃ (593 K) (value for 1 MPa hydrogen pressure). The relative standard deviations of 6.9% and 7.2%, respectively, were measured for absorption. The absorption plateau pressure of magnesium hydride varies between 0.08 and 0.14 MPa with an average of 0.10 MPa and a relative standard deviation of 17.3% at 280 ℃ (553 K). At 320 ℃ (593 K) the absorption plateau pressure results fall in the range 0.26-0.45 MPa, with a relative standard deviation of 17.6%. Kinetics curves were affected by much higher data dispersion than the PCI data. The enthalpy of absorption was -75.7 KJ/moleH2, with a relative standard deviation of 4.4%. The results highlight the importance of well denned measuring and reporting protocols as a base for future standard procedures.
