NOVELTY - The method for the production of hydrogen useful in fuel cells in mobile and stationary applications, comprises exposing steam from hydrogen compounds of the element of 4-6 main group, a mixture of steam of the hydrogen compounds and water vapor, a mixture of the steam and air or hydrocarbon aerosol particle by electromagnetic radiation for the production of hydrocarbon steam, hydrocarbon steam/water vapor mixture, hydrocarbon steam/air mixture or hydrocarbon-aerosol particle. The hydrocarbon steam is produced by evaporating fluid hydrocarbon through supplying thermal energy.    USE - Method for production of hydrogen useful in fuel cells in mobile and stationary applications.    ADVANTAGE - The method ensures fast and safe production of hydrogen with less effort and less energy consumption without using catalyst by avoiding soot formation.    DETAILED DESCRIPTION - The method for the production of hydrogen useful in fuel cells in mobile and stationary applications, comprises exposing steam from hydrogen compounds of the element of 4-6 main group, a mixture of steam of the hydrogen compounds and water vapor, a mixture of the steam and air or hydrocarbon aerosol particle by electromagnetic radiation for the production of hydrocarbon steam, hydrocarbon steam/water vapor mixture, hydrocarbon steam/air mixture or hydrocarbon-aerosol particle. The hydrocarbon steam is produced by evaporating fluid hydrocarbon through supplying thermal energy. The hydrocarbon steam/water vapor mixture is produced by evaporating the hydrocarbon by supplying the thermal energy and subsequently supplying the water vapor. The hydrocarbon steam/air mixture is produced through heating and evaporating of fluid hydrocarbon or hydrocarbon containing fluid and mixing the produced steam with air. The hydrocarbon-aerosol particle is produced through pressure automization of fluid hydrocarbon. The frequencies of the electromagnetic radiation of the energy equivalent to the resonance frequency correspond to the element hydrogen bond. Fuel is used as hydrocarbon and is kerosene, gasoline and diesel. The resonance frequency of the electromagnetic radiation is 4.28 eV. A microwave generator or laser is used for the production of electromagnetic radiation. The laser is gas laser, dye laser, solid body laser, color centre laser, a semiconductor laser or a free electron laser. The wave length of the electromagnetic radiation is 200-500 nm. The thermal energy is brought by evaporators.
