摘要： A process for obtaining hydrogen and oxygen from water in a two stage process including a first electrolysis stage performed in a two chamber cell wherein the chambers are separated by a membrane. Iodine is introduced into the cathodic chamber and hydrogen iodide is formed therein. Oxygen is formed in the anodic chamber and is removed as a product. The membrane conducts hydrogen ions and prevents the passage of the products HI and oxygen. In a second phase, hydrogen iodide is separated and removed from the cathodic chamber and is thermally decomposed into hydrogen and iodine. The iodine is recycled to the cathodic chamber and the hydrogen is recovered as a product.
