摘　　要：介绍了一种方便、实用且能有效制备高纯度氢气的新型制氢技术———NaBH4水解制备氢气。NaBH4(水溶液)与催化剂作用,水解产生氢气和一种水溶性盐———NaBO2。该反应中,氢的生成速度容易控制;制得的氢气纯度高,不需要纯化过程,可直接作为燃料电池的原料;催化剂可以循环使用;甚至在0℃下也可以生产氢气,无污染。另外,还介绍了本文发明的催化剂和相应的反应器体系,具有催化剂便宜,反应器安全、易于控制等特点。A safe, simple, compact process generating high-purity of hydrogen gas on demand from basestabilized, aqueous solutions of sodium borohydride（ NaBH4 ） is proposed. When NaBH4 solution reacts with the catalysts, it spontaneously hydrolyzes to form hydrogen gas and sodium borate, a water-soluble inert salt. Using aqueous solutions of sodium borohydride can reduce the dangers of H2 stored for a long time. In this reaction, the hydrogen generation rate can be easily controlled, and the hydrogen gas is very pure and needn＇t refine The catalysts can be circularly used. Furthermore, hydrogen gas can be produced under 0 ℃ and no pollution to environment. Also the catalysts and generators designed in author＇s laboratory are introduced, experiments show the catalysts are cheap, and the generators are safe and easily controlled.
