HYDROGEN RESERVOIR WITH EXCELLENT HEAT CONDUCTIVITY HYDROGEN RESERVOIR WITH EXCELLENT HEAT CONDUCTIVITY, CAPABLE OF INCREASING THERMAL CONDUCTIVITY IN A PRESSURE CONTAINER BY CONTAINING HYDROXIDE METAL IN A BOX FORMED IN THE PRESSURE CONTAINER BY FORMING A HYDROXIDE METAL HYDROGEN RESERVOIR

PURPOSE: A hydrogen reservoir is provided to increase thermal conductivity in a pressure container by containing hydroxide metal in a box formed in the pressure container by forming a hydroxide metal hydrogen reservoir. CONSTITUTION: A hydrogen reservoir has a pressure container(1) sealing hydrogen. Hydroxide metal(6) is arranged in a box(5) for passing hydrogen. Adjacent boxes are welded to each other on the surface facing the pressure container in a section method. The pressure container has a cylinder shape. The box is formed as a port shape. The boxes are piled in the pressure container to form a cover(3) of the adjacent box with a bottom side of one box. At least one filling/draw-out pipe(4) for passing the hydrogen is disposed in the central part of the pressure container. The pipe penetrates the box.
