Dynamic behaviour of heat and hydrogen transfer in a metal hydride chiller.

Author(s) : KANG B. H., PARK C. W., LEE C. S.

Summary

Transient transport processes of hydrogen and heat between two coupled reactors in a metal hydride chiller have been investigated experimentally. A pair of hydride reactors are designed to extend the contact surface between hydride and flowing hydrogen for fast kinetics. Lanthanum-nickel(4.7)-aluminium(0.3) is used for high plateau pressure and manganese-nickel(4.15)-iron(0.85) for lower plateau pressure, respectively. Dynamic correlations of pressure-temperature and temperature-concentration are investigated in a typical operational condition. The experimental results obtained lead to a better understanding of the underlying transport mechanisms.
