Abstract: A combined magnetohydrodynamic and electrochemical method for namely electric power generation through a hydrogen-oxygen fusion in a hydrogen fuel cell uses an electrolytic process of decomposing water to hydrogen and oxygen in a spiral magnetic electrolyser under the surface of a water environment, where the dynamization of the water environment in the water supply system of the spiral magnetic electrolyser is induced by negative pressure resulting from water being decomposed at the outlet of the spiral magnetic electrolyser. A combined magnetohydrodynamic and electrochemical facility for namely electric power generation comprising a hydrogen fuel cell including at least one spiral magnetic electrolyser (1), with its inlet (2) submerged under the surface of a water environment (3). Connected to the outlet (4) of such positioned spiral magnetic electrolyser (1) is a gas separator (5) separating produced hydrogen from oxygen and at least one hydrogen fuel cell (6) with an outlet for water (7).
