NOVELTY - A fuel gas generation apparatus has liquid supply unit, gas generation component accommodation which accommodates the chemical substance which generates chemical reaction, liquid permeation unit which permeates the liquid and is in contact with storage unit, liquid supply unit, constricting unit, external injection unit, direction supply unit, external opening-and-closing unit, and fuel-supply unit which supplies fuel to chemical reaction chamber (II) (4) that is connected with the chemical reaction space (I) (3).    USE - Fuel gas generation apparatus used for fuel cell.    ADVANTAGE - The fuel gas generation apparatus is environmental-friendly, economical, reduces the fuel consumption condition and efficiently generates fuel gas even at low pressure.    DETAILED DESCRIPTION - A fuel gas generation apparatus has liquid supply unit which supplies liquid continuous at fixed velocity, gas generation component accommodation which accommodates the chemical substance which generates chemical reaction and produces fuel gas when the liquid interposes, liquid permeation unit which permeates the liquid and is in contact with storage unit, liquid supply unit which supplied the liquid to the permeation unit and is equipped with exit(s), constricting unit which restricts the feed-rate and has the exit of the liquid supply unit, external injection unit which injects the liquid from the exterior of the liquid supply unit, direction supply unit provided with the function which prevents back flow of the liquid when it is not in pumping state, external opening-and-closing unit which opens and closes the liquid supply from the liquid supply unit by external operation, and fuel-supply unit which supplies fuel to chemical reaction chamber (II) that is connected with the chemical reaction space (I) which generates chemical reaction through the permeable film and produces fuel gas. The chemical reaction chamber (I) has space more than the space of chemical reaction space (II) and is connected with the exterior. The external injection unit is filled with the liquid in the liquid supply unit when the liquid is in the pumping state.
