Reversible hydriding and dehydriding reactions of perovskite-type hydride NaMgH3

Reversible hydriding and dehydriding reactions were experimentally confirmed in the perovskite-type hydride, NaMgH3. Nearly 6.0 mass% of hydrogen was released from NaMgH3 within 8 min at 673 K, and two plateau pressures of about 0.15 and 0.040 MPa were clearly observed in the p-c isotherm measurement at the same temperature.
