【摘要】 探究了Mg和Mg₁₇Al₁₂在Al₂（SO₄）₃溶液中的产氢性能.结果表明，303 K时Mg在0.70 mol/L的Al₂（SO₄）₃溶液中能完全反应，产氢量为993 mL/g,产氢速率为85 mL/（min·g）.Mg₁₇Al₁₂在0.30 mol/L的Al₂（SO₄）₃溶液中的产氢量更高，为1 100 mL/g,产氢速率为69 mL/（min·g）.连续添加Mg或Mg₁₇Al₁₂后，反应速率及产氢量均有所下降，这可能与铝形成水合物导致溶液黏稠有关.将制得的氢通过小型燃料电池后，产生的电流为92～94 mA,电压约为0.5 V.更多还原

【Abstract】 The hydrogen generation of Mg and Mg₁₇Al₁₂ in Al₂（SO₄）₃solution was investigated.The results indicate that Mg can completely react in 0.70 mol/L Al₂（SO₄）₃ solution at 303 K.The hydrogen yield and hydrogen generation rate are 993 mL/g and 85 mL/（min·g）,respectively.The hydrogen yield of Mg₁₇Al₁₂ in 0.30 mol/L Al₂（SO₄）₃ solution is as high as 1 100 mL/g and the hydrogen generation rate is 69 mL/（min·g）.After the continuous additions of Mg and Mg₁₇Al₁₂ bathes, the reaction rate and hydrogen generation decrease.This reason may be related to the increased viscosity of solution caused by the formation of aluminum hydrate.When the hydrogen passes throngh a small fuel cell, the generated current and voltage are 92～94 mA and 0.5 V, respectively.更多还原
