Abstract
【解決手段】 無機水素化物、金属塩化物、水とから成る組成物であって、前記無機水素化物、前記金属塩化物、前記水は、互いに接触して水素を発生する反応物とした。
【選択図】 なし
Description
NaBH4 + 2H2O => NaBO2 + 4H2
このように化学量論的には、水素化ほう素ナトリウムはほぼ同重量の水と反応が進むが、実際には大過剰の水を加えて反応効率を向上させている。無機水素化物の重量に対する水の重量の比率は、0.5〜2.22となることが好ましいとの発明の開示がある(例えば特許文献2参照)。この比率は無機水素化物を水溶液化したときの水素放出特性の点からであるが、水素貯蔵密度も6〜10wt%が得られ、この点でも有効性の高い組成となっている。
