美国研制出能把水分解成氢和氧的化学反应块(简称CRB),是由碱金属(如钠)及银、铝的荥剂和催化作用的合金混合而成的。此合金除含有铂外,还含有锗、锑、镓、铅:锌等十种先素中的一种。而合金与汞剂化合物的最佳重量比是1:2至1:3。其反应机理可解释为,水与碱金属如钠、铝反应放出氢,并生成Na_3Al(OH)_6。在 The United States has developed a chemical reaction block (CRB) that breaks down water into hydrogen and oxygen. It is made from a mixture of alkali metals (such as sodium) and silver, aluminum, and catalytic alloys. In addition to this alloy contains platinum, but also contains germanium, antimony, gallium, lead: zinc and other one of the ten kinds of precursor. The optimum weight ratio of the alloy to the amalgam compound is 1: 2 to 1: 3. The reaction mechanism can be explained as water and alkali metals such as sodium, aluminum release hydrogen, and generate Na_3Al (OH) _6. in
