産業上の利用分野
本発明は、ヒドラジン、メタノール等を燃料と
する液体燃料電池の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to improvements in liquid fuel cells that use hydrazine, methanol, or the like as fuel.
従来の技術
従来、液体燃料電池において、電池内部の温度
を調節する方法として電池外部として電池外部に
冷却器を設け、該冷却器を用いて空気極を直接空
冷することで電池内の温度を適当な温度になるよ
うに調節していた。Conventional technology Conventionally, in a liquid fuel cell, as a method of adjusting the temperature inside the cell, a cooler was provided outside the cell, and the air electrode was directly air-cooled using the cooler, thereby adjusting the temperature inside the cell to an appropriate level. The temperature was adjusted to the desired temperature.
発明が解決しようとする課題
しかし、温度依存性の高い空気極性能は、電池
温度が下がるより早く空気極性能が低下してしま
うという欠点があり、また、冷却器を設けたこと
により組立行程が複雑で体積効率も悪く、電気的
制御も必要となる為に動作が複雑になり、野外で
使用する時や振動がある場合など故障し易く、価
格面でも高価になるという問題があつた。Problems to be Solved by the Invention However, the air electrode performance, which is highly temperature dependent, has the disadvantage that the air electrode performance deteriorates faster than the battery temperature drops, and the provision of a cooler slows down the assembly process. They are complicated, have poor volumetric efficiency, require electrical control, which makes their operation complicated, and they are prone to breakdowns when used outdoors or when there is vibration, and they are expensive.

たは傾倒させるようにしたものである。Means for Solving the Problems The present invention solves the above problems by inserting a thin piece of heat-sensitive material with high thermal conductivity into the battery, and exposing the remaining part to the outside of the battery as a heat dissipation fin. The heat dissipation fins are made to stand upright or tilt by utilizing the change.

製の簡略化がなされるものである。Function By having the above structure, the highly thermally conductive flakes stand upright when the internal temperature of the battery is high and tilt when the temperature is low, making it possible to change the effective area that acts as a heat dissipation fin. The temperature of the battery body can be adjusted without directly cooling the high air electrode. Moreover,
Electrical control of a cooler or the like is not required, and battery production is simplified.

ができる。 A thin piece of flexible graphite, which is a heat-sensitive material with high thermal conductivity, is inserted into the battery frame 1 and the remaining part is exposed at the top of the battery to serve as the heat dissipation fin 2.The anolite in the anolite tank 3 is circulated by the pump 4, and the anolite Bimetal 6 made of heat-sensitive material is placed in the liquid reservoir 5 provided at the discharge port.
, the protrusion 7 connects the metal wire 8 between the heat dissipation fins 2 to the bimetal 6, and the heat dissipation fin 2 is made to stand upright or tilt by utilizing the change in shape of the bimetal 6 that occurs when the anorite temperature is high or low. This is used to adjust the battery temperature. That is, when the battery temperature is high, the heat dissipation fins 2 stand upright and are cooled by the fan 9, and the battery frame 1 into which the heat dissipation fins 2 are inserted is cooled by heat conduction. On the other hand, when the battery temperature is low, the heat dissipation fins 2 are tilted and overlapped.
The air blown by the fan 9 cools only a portion of one surface of the heat dissipation fin 2, and the balance between heat generation and heat dissipation is shifted, resulting in an increase in battery temperature. As mentioned above, like the battery frame 1 in this embodiment, the battery temperature is adjusted through the inserted portion of the heat dissipation fin 2, so that the air electrode, which is highly temperature dependent, is not cooled. Cell temperature can be adjusted without reducing the performance of the poles.

きる。 In this embodiment, a thin piece of flexible graphite is used for the radiation fin 2, but a thin piece of metal such as amorphous metal may also be used. Further, as for the heat-sensitive material, for example, a shape memory alloy can also be used.
発明の効果

価値甚だ大なるものである。Effects of the Invention As described above, according to the present invention, since the air electrode can be prevented from being directly cooled, the battery temperature can be adjusted without reducing the air electrode performance, which is highly temperature dependent. Since no cooler is used to adjust the temperature inside the battery, battery production can be simplified, and this has great industrial value, such as contributing to cost reduction.
