摘　　要：设计了一种全新概念的高效、安全、环保的铝-水储氢电池体系,该体系在对外输出电能的同时,还对外输出纯氢气。铝-水储氢电池体系主要是由正极、负极和电解液构成的密闭体系,阴极为采用化学还原法制备的活性炭担载镍(Ni/C)析氢催化剂制备的Ni/C膜电极,阳极为高活性铝合金,电解液为1mol/LNaCl中性溶液。本体系可以通过调节放电电流的大小来调节氢气的输出量。A new type of hydrogen storage cell was designed, which could output hydrogen gas and electric power steadily and continuously with high efficiency, safety and friendly environment. The cell was main composed of cathodic electrode, anodic electrode and electrolyte. The cathodic electrode was made of Ni/C electrocatalyst synthesized by impregnation-reduction method. The anodic electrode was aluminum alloy. The electrolyte was 1 mol/L NaCI solution. The output rate of hydrogen gas can be controlled just by adjusting the discharging current density of the alumnium-water cell.
