| 摘要 |
The rate of hydrogen generation in proton-exchange-membrane (PEM) fuel cells is greatly accelerated by mixing a first aqueous alkali borohydride solution with a second aqueous solution in the presence of one or more transition metal catalysts: wherein the first solution comprises (a) 5 to 50 wt % MBH4, where M is an alkali metal, (b) 5 to 40 wt % alkali hydroxide or alkaline metal hydroxide, and (c) the balance water, and wherein the second solution comprises (a) 51 to 100% water, and (b) the balance, if any, comprising at least one water-soluble additive.
