A cartridge structure based on solution of metal hydrides in a liquid reactant and passage of this solution over a catalytic surface is provided to generate a reaction and obtain hydrogen gas from these metal hydrides, comprised of: - At least one outer casing in the form of a closed container containing the created mixture; - At least one metal hydride tank containing the metal hydride, having a base plate in the form of a reversed truncated cone which aligns with an aperture on the top plate of the outer casing, and having a one way lid on this truncated surface; - At least one shaft passing through the centreline of the outer casing and lying between top and bottom plates, on which the propellers emplaced at varying levels with blades at various orientations are mounted with intervals, rotating on its own axis by means of a motor in order to mix the feed from the top plate of the outer casing on its way through the outer casing; - At least one extension placed on at least one blade of the propeller closest to the top plate of the outer casing among all the propellers mounted on the shaft, which is positioned to align with the aperture during rotation of the blade, in the form of an empty cylinder reaching towards the top plate of the outer casing, containing a spring and at least one spherical end attached to this spring on the surface aligned with the spring, pushed towards the top plate of the outer casing by the force applied by the spring and transferring the pushing force applied by the spring onto the bottom of top plate of the outer casing through the spherical end, which allows metal hydride from the metal hydride tank entry into the outer casing through the aperture by pushing the one way lid when the spherical end aligns with the aperture during rotation of the propeller on which it is located; - At least one hollow fibre coated with a catalytic metal promoting the hydrogen generating reaction in the chemical hydride solution composed of the metal hydride and the solvent blended by impact of the propellers and reacting during their passage over the channels; - At least one clamp securing the hollow fibres in their determined position, lying lengthwise inside the outer casing, passing through the apertures on the outer casing; - Retaining rods reaching into the outer casing to retain the clamp on its specified position on the outer casing; - Foils with at least one connection opening with dimensions allowing passage of the retaining rods, reaching towards the outer casing from the surface of the clamp facing the outer casing and securing a distance between them; - At least one liquid reactant input port connected with the liquid reactant tank, ensuring feed of liquid reactant into the outer casing. - At least one outer casing in the form of a closed container containing the created mixture; - At least one metal hydride tank containing the metal hydride, having a base plate in the form of a reversed truncated cone which aligns with an aperture on the top plate of the outer casing, and having a one way lid on this truncated surface;
