Abstract
Abstract Method of producing hydrogen which involves a magnesium reactant and an aqueous electrolyte with a dewatering agent, and an electrical energy source in contact with the magnesium reactant and the cathode. The dewatering agent reduces substantially the volume of magnesium hydroxide precipitation within the cell during its operation by freeing water from the precipitate thereby increasing its density.
