摘要:
A thermal conduction structure includes a heat receiving portion, a heat releasing portion, and actuators disposed between the heat receiving portion and the heat releasing portion. A path is defined from the heat receiving portion to the heat releasing portion through the actuator. The actuator is movable between a first position and a second position to correspond to an energy supplied from outside, and is contact with the heat receiving portion and the heat releasing portion, when the actuator is in the first position. The path has a non-contact part between the heat receiving portion and the heat releasing portion, when the actuator is in the second position.

An electric power generation system is mounted on a vehicle having a secondary battery, an electric load, and an internal combustion engine as a driving source consuming gasoline in a mixed fuel which mainly consists of the gasoline and ethanol. The electric power generation system has a fuel cell for generating electric power by electric chemical reaction and a fuel storage unit having an ethanol selection permeable membrane for separating the ethanol from the mixed fuel involving the ethanol and gasoline. On satisfying a given condition, the fuel cell receives the ethanol from the permeable membrane and initiates the generation of electric power, and supplies the generated electric power to at least one of the secondary battery and the electric load.

A method for manufacturing a carbon nano tube by a CVD method includes: supplying a carbon atom to a catalyzer for forming the carbon nano tube; and controlling an amount of carbon supply with time. In this method, super saturation of the carbon atom in the catalyzer is controlled appropriately. Thus, a caulking layer is prevented from being formed on the catalyzer, and therefore, the carbon nano tube having a sufficient length is obtained.

A hydrogen storage unit is provided with a hydrogen storage container containing a hydrogen absorption material, and a filter portion for eliminating impurities contained in stored hydrogen gas. Thereby, the impurities are eliminated from the stored hydrogen gas in the hydrogen storage container, and the hydrogen absorption material is prevented from being poisoned by the impurities. The filter portion can be provided either inside or outside the hydrogen storage container. An adsorbent for adsorbing the impurities can be used in the filter portion. The filter portion is provided with a heating means for enhancing the elimination of the impurities adsorbed in the filter portion, and can be recovered during operation.

A fiber aggregate contains fine carbon fibers and fine boron nitride fibers. Desirably the boron nitride fibers form an outer layer portion of the fiber aggregate and the fine carbon fibers form a core portion of the fiber aggregate. Desirably the fine carbon fibers and the fine boron nitride fibers are twisted with each other. Desirably the fine carbon fibers are carbon nanotubes and the fine boron nitride fibers are boron nitride nanotubes. Desirably the fiber aggregate further contains boron-containing fine carbon fibers. The fine boron nitride fibers are formed by substituting carbon atoms of fine carbon fibers by boron atoms and nitrogen atoms. The fiber aggregate is fabricated by mixing a fiber aggregate that contains fine carbon fibers with boron and heating the fiber aggregate mixed with the boron in a nitrogen atmosphere to transform some of the fine carbon fibers into fine boron nitride fibers.

A secondary battery charging system, mounted on a vehicle having an internal combustion engine, has a secondary battery, a fuel cell, a fuel storage unit, and a fuel supply controller. In order to start the engine of the vehicle, the engine requires the electric power from the secondary battery. The fuel storage unit stores a fuel to be supplied to the fuel cell. When a given condition is satisfied, the fuel supply controller instructs the fuel storage unit to supply the fuel to the fuel cell in order to start the operation of the engine of the vehicle. The fuel cell thereby starts the generation of the electric power by performing electric chemical reaction and supplies the generated electric power to the secondary battery. The secondary battery supplies the electric power to the engine of the vehicle. The engine initiates its operation.
