Description

本発明は、燃料電池へ燃料として特にメタノール溶液を有する液体燃料を供給する新規な燃料カートリッジに関する。   The present invention relates to a novel fuel cartridge for supplying a liquid fuel having a methanol solution as a fuel to a fuel cell.

電子機器の小型化、高性能化に伴い携帯用情報端末機器の普及が急速に進んでいる。従来、携帯用情報端末機器の電源としては、Ni/Cd電池、Ni/H電池、Liイオン電池等の二次電池が使われていた。しかし高性能化によって携帯用情報端末機器の消費電力が増加傾向にあり、従来の二次電池ではエネルギー密度が低いため消費電力の増加量に追随できず、携帯用情報端末機器の駆動時間が短くなることが考えられる。   With the downsizing and high performance of electronic devices, the spread of portable information terminal devices is rapidly progressing. Conventionally, secondary batteries such as Ni / Cd batteries, Ni / H batteries, and Li-ion batteries have been used as power sources for portable information terminal devices. However, power consumption of portable information terminal devices is increasing due to high performance, and conventional secondary batteries have low energy density, so they cannot follow the increase in power consumption, and the driving time of portable information terminal devices is short. It is possible to become.

エネルギー密度の高い電池としてダイレクトメタノール燃料電池があり、二次電池とは違い充電の必要がなく、燃料補給により携帯用情報端末機器は長時間駆動が可能である。
燃料カートリッジから燃料電池へのメタノール溶液燃料の補給方法が特許文献１に開示されている。燃料カートリッジの内部が2つの部屋に分かれており、1室には燃料、2室には吸水性材料が収納されている。燃料カートリッジを電子機器に差込み、毛細管現象により発電時に生じた生成水を燃料カートリッジ内の吸水性材料が吸水、膨張する。吸水性材料の吸水、膨張により燃料を送り出す仕組みである。 There is a direct methanol fuel cell as a battery having a high energy density. Unlike a secondary battery, charging is not required, and portable information terminal equipment can be driven for a long time by refueling.
Patent Document 1 discloses a method for supplying methanol solution fuel from a fuel cartridge to a fuel cell. The interior of the fuel cartridge is divided into two chambers. One chamber contains fuel and two chambers contain water-absorbing materials. The fuel cartridge is inserted into an electronic device, and the water-absorbing material in the fuel cartridge absorbs and expands the generated water generated during power generation by capillary action. This is a mechanism for sending out fuel by absorbing and expanding the water-absorbing material.

又、特許文献２には、液体燃料容器からその容器内の圧力を一定に保ちながら過不足がないように外部に液体燃料を放出しながら液体燃料を供給することが示されている。   Further, Patent Document 2 shows that liquid fuel is supplied from a liquid fuel container while discharging the liquid fuel to the outside so that there is no excess or deficiency while keeping the pressure in the container constant.

特開2003-92128号公報Japanese Patent Laid-Open No. 2003-92128 特開2001-93551号公報JP 2001-93551 A

燃料電池を搭載した電子機器を使用する場合、燃料の迅速、かつ確実な補給が要求される。燃料補給が遅く、また不確実な場合、燃料電池を搭載した電子機器が動かない問題が生じる。   When an electronic device equipped with a fuel cell is used, quick and reliable fuel supply is required. If refueling is slow or uncertain, there will be a problem that the electronic device equipped with the fuel cell does not move.

又、特許文献１に記載の方法では、吸水性材料が吸水、膨張がない場合、燃料カートリッジは燃料電池へ燃料を供給しない。そのため、燃料カートリッジから燃料電池への燃料補給は迅速、かつ確実な補給ができない。更に、特許文献２においては燃料容器内の圧力が反応によって生じるガスの影響を受けるので燃料電池への燃料補給を確実に補給することができない。   In the method described in Patent Document 1, when the water absorbing material does not absorb water or expand, the fuel cartridge does not supply fuel to the fuel cell. For this reason, refueling from the fuel cartridge to the fuel cell cannot be performed quickly and reliably. Furthermore, in Patent Document 2, since the pressure in the fuel container is affected by the gas generated by the reaction, it is not possible to reliably supply fuel to the fuel cell.

本発明の目的は、燃料カートリッジから燃料電池に燃料供給を行う際、必要な供給量を人為的及び機械的に確実に行うことができる燃料カートリッジを提供することにある。   An object of the present invention is to provide a fuel cartridge that can reliably and manually and reliably perform a necessary supply amount when fuel is supplied from a fuel cartridge to a fuel cell.

本発明は、燃料を収納する燃料室となる燃料カートリッジ筐体と、前記筐体内の燃料を前記筐体内から燃料電池に強制的に供給する人為的又は電気的な押圧手段とを有することを特徴とする燃料カートリッジにある。この押圧手段は吸引を行うことができ、燃料電池内の内容物を吸引して除去することができる。   The present invention includes a fuel cartridge housing serving as a fuel chamber for storing fuel, and artificial or electrical pressing means for forcibly supplying the fuel in the housing from the inside to the fuel cell. Is in the fuel cartridge. The pressing means can perform suction, and the contents in the fuel cell can be sucked and removed.

本発明における押圧手段は、ピストンを動かすための回転部を有し、この回転部の正確な回転によって押圧手段としてのピストンを正確に駆動させ、燃料を強制的に必要量を燃料電池へ供給することができる。   The pressing means in the present invention has a rotating part for moving the piston, and the piston as the pressing means is accurately driven by the accurate rotation of the rotating part to forcibly supply the required amount of fuel to the fuel cell. be able to.

又、本発明に係わる押圧手段としてのピストンは、螺旋構造によって駆動する機械的な構造とするものである。ピストンの駆動を螺旋構造によって行うことで、注入したい量の燃料を正確に燃料電池に供給することができる。注射器タイプのピストンでは、途中で燃料の注入を止めるのが困難で、正確な注入量でピストンを動かすことが困難である。しかし、ピストンを螺旋構造とする駆動構造とすることで、回転部を回転させない限りピストンは動かないものである。   The piston as the pressing means according to the present invention has a mechanical structure driven by a spiral structure. By driving the piston with a spiral structure, the amount of fuel to be injected can be accurately supplied to the fuel cell. With a syringe-type piston, it is difficult to stop fuel injection halfway, and it is difficult to move the piston with an accurate injection amount. However, by adopting a drive structure in which the piston is a spiral structure, the piston does not move unless the rotating part is rotated.

具体的には、本発明は、燃料を収納する燃料室となる燃料カートリッジ筐体と、該筐体内を接触摺動する先端板と、該先端板に一端が接続された接続棒と、該接続棒の他端に接続され前記接続棒を駆動する回転部と、該回転部に設けられた螺旋体と前記筐体に設けられた螺旋体との嵌合により前記回転体の回転により前記接続棒を通して前記先端板を駆動して前記燃料を燃料電池に供給することを特徴とする燃料カートリッジにある。回転部に設けられる螺旋体はその外周又は内周のいずれでも良く、又筐体に設けられる螺旋体はその外周又は内周のいずれでも良く、互いに嵌合し合うようにすれば良い。   Specifically, the present invention relates to a fuel cartridge housing serving as a fuel chamber for storing fuel, a tip plate that contacts and slides within the housing, a connecting rod having one end connected to the tip plate, and the connection The rotating portion connected to the other end of the rod and driving the connecting rod, and the helical body provided in the rotating portion and the helical body provided in the housing are fitted to each other through the connecting rod by the rotation of the rotating body. The fuel cartridge is characterized in that the tip plate is driven to supply the fuel to the fuel cell. The spiral body provided in the rotating part may be either the outer periphery or the inner periphery, and the spiral body provided in the housing may be either the outer periphery or the inner periphery, and they may be fitted to each other.

更に、本発明は、燃料を収納する燃料室となる燃料カートリッジ筐体と、該筐体内を接触摺動する先端板と、該先端板に一端が接続された接続棒と、該接続棒の他端に接続され前記接続棒を駆動する回転部と、該回転部に設けられた螺旋体と前記接続棒に設けられた螺旋体との嵌合により前記回転体の回転により前記接続棒を通して前記先端板を駆動し前記燃料を燃料電池に供給することを特徴とする燃料カートリッジにある。前記燃料カートリッジ筐体の一端を塞ぐ蓋を有する。   Further, the present invention provides a fuel cartridge housing serving as a fuel chamber for storing fuel, a tip plate that contacts and slides within the housing, a connecting rod having one end connected to the tip plate, and other than the connecting rod. The tip plate is passed through the connecting rod by rotation of the rotating body by fitting a rotating portion connected to the end to drive the connecting rod, and a helical body provided in the rotating portion and a helical body provided in the connecting rod. The fuel cartridge is driven to supply the fuel to the fuel cell. A lid for closing one end of the fuel cartridge housing;

又、本発明は、燃料カートリッジ筐体の内部を2つの部屋に分け、第１室が燃料室、第2室が空気収納室とし、この空気収納室に電子機器からポンプを使い空気を供給して燃料カートリッジ内の圧力を上昇させて、燃料室から燃料を燃料電池に供給するものである。
具体的には、本発明は、燃料カートリッジ筐体内に設けられた燃料を収納する燃料室となる燃料室膜と、前記筐体内に設けられ前記燃料室膜の外周を取り囲む空気収納室とを有し、燃料電池の電源を通して駆動する空気供給手段により前記空気収納室への空気の供給によって前記燃料室膜内の前記燃料を前記燃料電池に供給することを特徴とする燃料カートリッジにある。前記燃料カートリッジ筐体の外周に前記燃料電池への挿入位置を設定する少なくとも１個の突起を有する。 In the present invention, the interior of the fuel cartridge housing is divided into two chambers. The first chamber is a fuel chamber and the second chamber is an air storage chamber. Air is supplied to the air storage chamber from an electronic device using a pump. Thus, the pressure in the fuel cartridge is increased and fuel is supplied from the fuel chamber to the fuel cell.
Specifically, the present invention includes a fuel chamber film that is a fuel chamber that stores fuel provided in a fuel cartridge casing, and an air storage chamber that is provided in the casing and surrounds the outer periphery of the fuel chamber film.
