NOVELTY - A galvanic hydrogen generator system (100) comprises container(s) adapted to contain a galvanic cell(s), and comprising volume in excess of five gallons, construction seam(s) (114), hydrogen gas storage headspace(s), and hydrogen gas release valve(s), where construction seam(s) is permanently sealed, and the container(s) is adapted to hold at least one quantity of water relative to the quantity of an anode(s) to prevent overheating resulting in passivation of the anode(s).    USE - The galvanic hydrogen generator system is used for generating hydrogen gas from water, useful as fuel for vehicle engines or hydrogen-fueled internal combustion engines or gasoline/diesel-powered internal combustion engines.    ADVANTAGE - The system provides for efficient, safe, and easy hydrogen generation from water without the need to supply electrical power from outside the hydrogen generator (110); provides simple modification of gasoline or diesel-powered internal combustion engines to run at least partially on hydrogen fuel; and is inexpensive and handy. The users will benefit from using Underwriters Laboratories listed galvanic energy appliance because users will not be required to obtain additional regulatory approval to install and use galvanic energy appliance at their home or business.    DETAILED DESCRIPTION - A galvanic hydrogen generator system comprises galvanic cell(s) comprising an anode(s) including magnesium, cathode(s) comprising iron, and a buffer(s) (comprising aluminum) having an electrochemical potential between the anode(s) and cathode(s); and container(s) adapted to contain the galvanic cell(s), and comprising volume in excess of five gallons, construction seam(s), hydrogen gas storage headspace(s), and hydrogen gas release valve(s), where construction seam(s) is permanently sealed, the anode(s) initially weighs greater than or equal to 7 pounds, and the container(s) is adapted to hold at least one quantity of water relative to the quantity of the anode(s) to prevent overheating resulting in passivation of the anode(s), the galvanic hydrogen generator system further comprising an electrolyte(s) (140) including at least one quantity of water, where electrolyte(s) comprises a solution(s) of 20 wt.% sea salt in water.    DESCRIPTION OF DRAWING(S) - The figure shows a section of a large galvanic hydrogen generator illustrating the galvanic corrosion of the stack, with an expanded detail.
