Popis:	An experimental method is described which permits rapid characterization of hydride modules without requiring internal measurement of the bed temperature. The time to charge or discharge is measured as a function of the hydrogen pressure. A pressure-to-temperature transformation which relies on reversible metal hydride thermodynamics is applied to determine the bed temperature. This transformation facilitates conventional heat transfer analysis on hydride modules. Results are presented for the charging of a 0.375 in (0.95 cm) tubular hydride module. The time to 90% charge is less than 5 min when the temperature difference between the LaNi5 bed and the external cooling water exceeds 14 °C. This result compares very favorably with laboratory reactors designed for rapid heat transfer.
