    摘要： A fuel cell system for directly converting chemical energy of a fuel into electric energy electrochemically. A fuel cell has a cathode and an anode. A main hydrogen absorbing alloy supplies a hydrogen gas to the anode of the fuel cell during steady-state operation of the system. An auxiliary hydrogen absorbing alloy originally having a higher hydrogen gas absorbing/desorbing equilibrium pressure than the main hydrogen absorbing alloy at an equal temperature supplies a hydrogen gas to the anode until the equilibrium pressure of the main hydrogen absorbing alloy, which is supplied an exhaust gas from the fuel cell is equal to a hydrogen gas absorbing/desorbing equilibrium pressure of the auxiliary hydrogen absorbing alloy, the auxiliary hydrogen absorbing alloy receiving the hydrogen gas from the main hydrogen absorbing alloy during steady-state operation.

    摘要： In order to make a thermal utilization system operable in a stable and efficient condition regardless the variation of the operating heat source used, the system is provided with three hydrogen absorbing alloys having different pressure-temperature characteristics, wherein absorption/desorption of hydrogen gas is performed in two steps, i.e. the hydrogen gas desorbed from a first alloy is absorbed by a second alloy at a predetermined pressure, and is absorbed by the third alloy at a higher pressure after it is desorbed from the second alloy in a case when the temperature of the operating heat source is low, while the hydrogen gas desorbed from the first alloy is directly transported from the first alloy to the third alloy to be absorbed there when the temperature of the operating heat source is high. Alternatively, two hydrogen absorbing alloys having different pressure-temperature characteristics are used in such a way that, when the temperature of the operating heat source is low, the hydrogen gas desorbed from the first alloy is pumped to the second alloy to be absorbed there, but the gas is directly transported from the first alloy to the second alloy to be absorbed there when the temperature of the operating heat source is high.

    摘要： The invention relates to an apparatus for measuring the gas absorbing and/or desorbing characteristics of a substance having a property to absorb a gas. The apparatus comprises a sample container for containing the substance, a gas storage connected to the sample container for storing the gas until a predetermined pressure is reached, a gas supply source for supplying the gas to the gas storage, a first valve provided on a line connecting the gas supply source to the gas storage, a second valve provided on the line between the first valve and the gas storage, and a third valve provided on a gas discharge line connected to the line between the first and second valves, the first to third valves being each a two-position valve having an open position and a closed position, the valves defining a region thereby surrounded and serving as a preliminary storage for temporarily holding the gas when the gas is supplied or discharged. The substance having the gas absorbing property is, for example, a hydrogen absorbing alloy, and the gas is hydrogen.
