PURPOSE: To provide the title reaction tank so designated that plural trays are installed within a reaction tank and a hydrogen-occlusive alloy is put to each tray, thereby improving the penetrability of H2 gas into the alloy layer and preventing the reaction tank from breaking failure due to the expansive force of the alloy.
CONSTITUTION: The objective reaction tank 1 with its section roughly cylindrical, is comprised of the lower and upper tanks 1a and 1b, the tank 1a being fitted with a ring 9, on which a tray 3d made of e.g. aluminum alloy is mounted. The interior of the tray 3d is provided with a coil pie for cold heating 4 to pass a coolant from a tank 12 via the tank 1a, the upper end of said pipe 4 is connected with a second pipe 4 in a tray 4c. Similarly, the tank 1b is also provided with trays 3aW3c and pipes 4, and a hydrogen-occlusive alloy 7 is put into each tray 3. When H2 is introduced from a line 11 into the tank 1 said gas enters, as the arrow B along with the arrow A, the respective trays 3 and penetrates through the surfaces of the alloy layers 6 in the respective trays 3 into their interiors. Thus, the penetrability of the H2 gas into the layers 6 is improved, thereby protecting the wall of the tank 1 from damage due to the expansion of said alloy.
