Outline of Final Research Achievements

Emission of hydrogen gas from water-splitting and hydrogen-absorbing metal-oxide ceramics layered hydrogen storage materials by microwave heating in vacuum has been measured by means of gas-chromatography. In experiments, a Pt/Li2ZrO3/Pt sandwich specimen of 1g in weight was rapidly heated for 3 min in a glass vessel of 1.3 liter in volume evacuated using a microwave heating cooker, 3 times. On 1st heating, just after start of the heating, emission of pink light of discharge of hydrogen gas emitted was observed. On 2nd heating, the light emission was observed. On 3rd heating, the color of light emitted was changed from pink, via re-brown, to orange.
Total amounts of hydrogen gas emitted has been estimated to be 0.66 m%, namely 8.6 cm3. This result indicates the that volume ratio of hydrogen gas emitted to specimen to be about 30 and also that a high pressure of hydrogen gas is able to be produced by selection of volume ratio of specimen to hydrogen containing vacuum vessel.
