Apparatus and method for on-board production of fuel for a fuel cell car

An apparatus for producing fuel for a fuel cell car comprising:

• a main reaction chamber including an aluminum coil and configured to produce gas;
• a sub-chamber including a sodium aqueous solution, the sub-chamber connected to the main reaction chamber to allow the produced gas to flow between the sub-chamber and the main reaction chamber;
• a circulation pump configured to supply a sodium hydroxide aqueous solution in the sub-chamber to the main reaction chamber when producing the fuel, and further configured to return the sodium hydroxide aqueous solution in the main reaction chamber to the sub-chamber when stopping production of the fuel;
• and
• a separator configured to separate hydrogen gas from the produced gas, and supply the hydrogen gas to a fuel cell,
• wherein the main reaction chamber includes a winding member and a restriction frame, the winding member configured to wind a coil while rotating at the center and the restriction frame configured to restrict the thickness of the wound coil.
