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.
