    摘要: In a fuel cell system 4 in which electricity is generated by a fuel cell 4 supplied with the hydrogen gas created from a reforming reaction and the electricity is supplied to an external load 12, an electric buffer CAPA for storing surplus electricity or supplementing insufficient electricity is located between the fuel cell 4 and the external load 12, and a hydrogen buffer MHB for accommodating surplus hydrogen gas and supplementing insufficient hydrogen gas is located between a reforming device 2 and the fuel cell. Where electricity consumption in the load 12 increases abruptly, necessary electricity is supplied with the assistance of the electric buffer CAPA and hydrogen buffer HMB.

    摘要: In order to achieve optimal weight and volume of a hydrogen storage apparatus, there is provided a method of charging hydrogen to a hydrogen storage apparatus. The hydrogen storage apparatus 1 includes a hydrogen storage means accommodating a hydrogen occlusive alloy (MH tank assembly) 3, and a hydrogen tank (high-pressure hydrogen tank) 2 that is provided separately from the hydrogen storage means 3 and stores hydrogen in gaseous form. Hydrogen is filled so that a pressure in the hydrogen tank is higher than that in the hydrogen storage means. A decompressing means (charger regulator) 6 is provided for reducing a pressure of hydrogen fed to the hydrogen storage apparatus 1 to maintain the pressure in a predetermined pressure range. The hydrogen storage apparatus 1 may include more than one of the hydrogen occlusive alloy tank (MH tank) 31.

    摘要: The object of the invention is to provide a high performance metal hydride tank apparatus, which is capable of discharging the hydrogen gas stored in the metal hydride in the tank from throughout the metal hydride efficiently and rapidly. In the process of the hydrogen gas discharge, the metal hydride contained near the inner circumferential surface of the tank absorbs the heats by the temperature raised tank and starts discharging the hydrogen gas. The discharged hydrogen gas absorbs the heat from the inner circumferential wall efficiently, flowing along the inner circumferential wall rapidly guided by the cylinder-like baffle. Further, the discharged hydrogen gas flows through the hydrogen gas flow channel, which is formed into sections by the cylinder-like baffle in the tank, and travels throughout the metal hydride, thus heating up the metal hydride rapidly and discharging the hydrogen gas efficiently from throughout the alloy.
