Hydrogen generation system of the present invention are all demand systems that are operated to replenish hydrogen gas to a low pressure storage tank or vessel as hydrogen is drawn therefrom, providing a system that is suitable for use as a portable system. The invention employs electrical and mechanical arrangements that provide for opening an outer coating that has been formed over a reactive material, such as sodium, so as to expose that reactive material to water, generating hydrogen from a chemical reaction therebetween. The electrical system employs a bank of cells, with each cell electrically connected through a controller to a power source and contains a measured volume of a light salt and water solution and a sodium pellet that is coated with aluminum, or other appropriate metal, and provides for passing a current to a select cell to break down the pellet aluminum coating and expose the pellet reactive material to the water to generate hydrogen. Sodium pellets are coated with a soft plastic, or the like, and are maintained in water and include a static pressure source to operate, when the hydrogen gas pressure falls below the pressure of that static source, a piston to move a selected pellet into a blade, or the like, to open that pellet to the water to chemical react and generate hydrogen gas to restore the system pressure to a pressure that is greater than that of the static source.
