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.

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又は電気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, when performing the fuel supplied from the fuel cartridge to the fuel cell is to provide a human or electrically fuel cartridge capable of reliably performing the feed rate required.

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.

The fuel cartridge is characterized in that it presses and supplies the fuel in the fuel chamber membrane to the fuel cell.

燃料カートリッジが空気収納室を有する場合、電子機器へ燃料カートリッジを挿入した際、電子機器のポンプから燃料カートリッジ内の空気収納室へ空気を送るための中空針、燃料室から燃料電池へ燃料を送るための中空針の位置決めをすることが重要である。そのため燃料カートリッジの位置決めをする方法として、燃料カートリッジ筐体外周に突起物、凹みを設ける。突起物および凹み形状、大きさ、長さ等は特に限定されない。   When the fuel cartridge has an air storage chamber, when the fuel cartridge is inserted into the electronic device, a hollow needle for sending air from the pump of the electronic device to the air storage chamber in the fuel cartridge, fuel is sent from the fuel chamber to the fuel cell It is important to position the hollow needle for this purpose. Therefore, as a method for positioning the fuel cartridge, a protrusion and a recess are provided on the outer periphery of the fuel cartridge housing.

The hollow needle provided at the fuel supply port to the fuel cell of the electronic device is inserted by the insertion, the fuel chamber cover 3 is broken, and the fuel cartridge housing portion of the electronic device and the fuel chamber 2 are connected. A scale is displayed on the outer peripheral surface of the fuel cartridge housing 1 so that the volume therein can be seen. The fuel chamber lid 3 is preferably made of rubber so that it can be used repeatedly.

回転部6及び接続棒5の接する箇所に回転部の螺旋8、接続棒の螺旋9が施されている。接続棒5は先端板4に固定され、又、回転部の螺旋体8が設けられている部分は燃料カートリッジ筐体1に対して回転可能に接続されている。回転部6を回転させることでピストンの先端板4が左右に動く。ピストンの先端板4が前進すれば燃料が燃料電池内へ供給され、先端板4が後退すれば燃料電池内の水、不要な燃料等を燃料カートリッジ内へ回収することができる。 Rotation unit 6 and the connecting rod of the rotating part at a position in contact with the 5 helix 8, helix 9 of the connecting rod is applied.

When the tip plate 4 of the piston moves forward, fuel is supplied into the fuel cell, and when the tip plate 4 moves backward, water in the fuel cell, unnecessary fuel, etc. can be collected into the fuel cartridge.

本実施例によれば、燃料カートリッジ内に充填したメタノール水溶液燃料を人為的、機械的に迅速かつ確実に必要な供給量を正確に燃料電池へ燃料補給することができる。   According to this embodiment, it is possible to refuel the fuel cell with the required supply amount of the methanol aqueous solution fuel filled in the fuel cartridge quickly and reliably artificially and mechanically.

図3は、本発明における燃料カートリッジの概略図を示し、その正面図(a)及びそのA-A断面図(b)である。燃料カートリッジは燃料カートリッジ筐体1、シリコーンゴムからなる蓋10、燃料室膜11、3箇所の位置あわせ突起12、燃料室膜保護板13から構成される。燃料カートリッジ筐体1、燃料室膜11、位置あわせ突起12、燃料室膜保護板13はポリエチレンを用いた。空気収納室14への空気圧の表示によって燃料室膜11の中の体積が分かるように目盛が表示されている。燃料室蓋10は繰り返し使用できるようにするためゴム製とする。   FIG. 3 is a schematic view of a fuel cartridge according to the present invention, and is a front view (a) and a cross-sectional view AA thereof (b).

At the same time, a hollow needle for supplying fuel to the fuel cell is inserted into the fuel chamber 2. Air is sent to the air storage chamber 14 by a pump in the electronic device, the pressure in the fuel cartridge rises, and the fuel is pushed out to the fuel cell. At this time, the pump in the electric device is driven by a secondary battery such as a Li battery.

電子機器のポンプから空気が表示された目盛に従って燃料カートリッジ内の空気収納室14へ送られるため、中空針を通して燃料室2から必要量の燃料が燃料電池へ供給される。中空針の位置決めのため、燃料カートリッジは外周の3箇所に突起物からなる位置合わせ突起12を有する。   Since air is sent from the pump of the electronic device to the air storage chamber 14 in the fuel cartridge according to the displayed scale, the required amount of fuel is supplied from the fuel chamber 2 to the fuel cell through the hollow needle. For positioning of the hollow needle, the fuel cartridge has alignment protrusions 12 made of protrusions at three positions on the outer periphery.
