Abstract
A method for producing hydrogen according to a hybrid process. A low oxide, hich is formed at a high temperature from a higher oxide accompanied by splitting-off of oxygen, is introduced into an aqueous electrolyte and is reoxidized anodically along with simulataneous cathodic hydrogen generation. The oxide is returned into the high temperature range. As an oxide, antimony oxide, especially antimony tetraoxide, is used, with the oxide being formed anodically in a melt-flow electrolysis and being decomposed again into antimony trioxide and oxygen at approximately 850.degree. to 1000.degree. C. As an electrolyte, an alkali melt, and especially a melt having a sodium hydroxide base, may be used. The electrolyte may be formed by a possibly salt, especially sodium fluoride, containing mixture of sodium hydroxide and antimony trioxide in a mole ratio of 1:0.5 to 1:5.0, with a water content of approxaimately 1 to 5% by weight. The anode chamber is separated from the cathode chamber by a .beta.-aluminum oxide separating wall.
