The results show that the originated materials for electrolyte aluminium is Al2O3 and AlF3 has good property to absorb vapour. After the water contained in the originated materials goes into electrolyte, AlF3 reacts with water hydrolyzed and the rest of water is electrolyzed into hydrogen and oxygen. Hydrogen enteres aluminum liquid by diffusing and autoecious in Al2O3, which is the main source of hydrogen in electrolyte aluminum liquid.

研究结果表明：电解铝所用的原材料(Al2O3和AlF3等)有良好的吸水性能，所携带的水分进入电解液后，或与氟化盐发生水解反应，或被电解成氢和氧，析出的氢通过扩散和Al2O3寄生机制进入铝液，这是电解铝液中氢的主要来源。
