Description

本考案は、一種の燃料電池装置の流路板構造に関り、特に両面流路板で、両側の表面で燃料の流場構造を形成し、また、その両側面にそれぞれ燃料電池板を密着したものを提供することに関するものである。   The present invention relates to a type of fuel cell device flow path plate structure, in particular, a double-sided flow path plate that forms a fuel flow field structure on both sides, and the fuel cell plates are in close contact with both sides. It is about providing what you did.

従来の燃料電池の流路板は、その片面上に例えば流路溝のような流場構造を設置することで、燃料電池の膜電極接合体をこの片面上に密着することしか選択がなく、この種の流路板と燃料電池の結合方法は、平面で、且つ、大面積型の燃料電池で言うと、流路板の面積が少なくとも燃料電池の面積程度に近いものとならなければならず、これにより燃料電池の各膜電極接合体が燃料供給を得られることができることから、従来の流路板の構造は、明らかに小型化という燃料電池装置に適用されることが無い。   The flow path plate of the conventional fuel cell has only a choice of closely attaching the membrane electrode assembly of the fuel cell on this one side by installing a flow field structure such as a channel groove on one side, This type of flow path plate and fuel cell coupling method is flat and, in the case of a large area fuel cell, the area of the flow path plate must be at least close to the area of the fuel cell. Thus, since each membrane electrode assembly of the fuel cell can obtain fuel supply, the structure of the conventional flow path plate is obviously not applied to the fuel cell device of downsizing.

本考案の考案者は、従来の流路板の欠陥を鑑み、一種の両面流路板構造を改良・創作することを切望したのである。   The inventor of the present invention was eager to improve and create a kind of double-sided channel plate structure in view of the defects of the conventional channel plate.

本考案の主な目的は、一種両面流路板構造で、流路板の上、下両表面にそれぞれ燃料の流場構造を形成することにある。   The main object of the present invention is to form a fuel flow field structure on both the upper and lower surfaces of the flow path plate in a kind of double-sided flow path plate structure.

本考案の別な目的は、一種の両面流路板構造で、燃料電池の全体体積を大幅に低下させることにある。   Another object of the present invention is to provide a kind of double-sided flow path plate structure that significantly reduces the overall volume of the fuel cell.

上記目的を達成するため、本考案は、板体と、該板体のそれぞれ上表面と下表面を形成し、この中の各上部、下部槽体の設置位置が、燃料電池板の各膜電極接合体の設置位置と対応する上部槽体及び下部槽体を含む一種の両面流路板構造を提供することにある。   In order to achieve the above object, the present invention forms a plate body and upper and lower surfaces of the plate body, and the installation positions of the upper and lower tank bodies in the plate body are the membrane electrodes of the fuel cell plate. It is providing the kind of double-sided flow-path board structure containing the upper tank body and lower tank body corresponding to the installation position of a joining body.

本考案である両面流路板の長所と効果は、明らかに増進され、それは以下のとおりである。
1.両面流路板の上、下両面においてそれぞれ燃料を供給することができ、両面流路板を具備する燃料電池装置の小型化が容易に実行できる。
2.両面流路板の各支持ブロックの支持作用を介することで、燃料電池板が安全に両面流路板の表面に密着することができる。

1. Fuel can be supplied on both the upper and lower surfaces of the double-sided flow path plate, and the fuel cell device including the double-sided flow path plate can be easily downsized.
2. The fuel cell plate can safely adhere to the surface of the double-sided flow path plate through the support action of each support block of the double-sided flow path plate.

The fuel cell plate 1 mainly includes a main substrate 11, a plurality of membrane electrode assemblies 12 fitted in a local area of the substrate 11, and a collection formed on the upper and lower surfaces of the substrate 11, respectively. The electric layer 13 is included. The upper and lower two fuel cell plates 1 are sandwiched between the two-sided flow path plates 2 of the present invention, and flow inside the double-sided flow path plates 2 as, for example, liquid fuel of methanol solution, gaseous fuel of hydrogen gas, etc. After the fuel flows into the membrane electrode assembly 12, currents are generated in the upper and lower two fuel cell plates 1, and further in the current collecting layers 13 of the respective fuel cell plates 1. Power is provided to the outside by electrically connecting the finally generated supply voltage to the signal port 15 through the formed series-parallel electrical connection.

図３は、本考案である両面流路板構造の上表面の平面上面見取図、及び、図４は本考案である両面流路板構造の下表面の平面上面見取図である。図３と図４において、流路板2の基材は、板体21で、この板体21は例えば金属基材、プラスチック基材などを用いることができ、板体21の上表面と下表面でそれぞれ少なくとも1個以上の上部槽体23Aと下部槽体23Bをそれぞれ形成し、且つ、各表面に配置したこれら槽体23A、23Bの形成位置は、燃料電池板1の各膜電極接合体 12の位置と対応している。同時に、各槽体23A、23Bが板体21の上、下表面でそれぞれ注入流路25、及び、排出流路27を突出形成し、且つ、注入流路25の末端と排出流路27の末端において、板体21の側辺でそれぞれ注入口25A、及び、排出口27Aを形成する。注入口25Aと排出口27Aの配置位置は、板体21の同一側辺に位置することができ、さらに、配置位置が信号用ポート15と同一側の方向に位置することで、同時に燃料の注入、或いは、排出、及び、電気的な接続などの連結という利便性を達成することができる。   3 is a plan view of a top surface of the upper surface of the double-sided flow path plate structure according to the present invention, and FIG. 4 is a plan view of a top surface of the lower surface of the double-sided flow path plate structure according to the present invention. 3 and 4, the base material of the flow path plate 2 is a plate body 21, and the plate body 21 can be, for example, a metal base material or a plastic base material. And at least one or more upper tank bodies 23A and lower tank bodies 23B are formed, and the positions of the tank bodies 23A and 23B arranged on the respective surfaces are the membrane electrode assemblies 12 of the fuel cell plate 1. Corresponds to the position of. At the same time, the tank bodies 23A and 23B project the injection flow path 25 and the discharge flow path 27 on the upper and lower surfaces of the plate body 21, respectively, and the end of the injection flow path 25 and the end of the discharge flow path 27 In FIG. 2, the injection port 25A and the discharge port 27A are formed on the sides of the plate body 21, respectively. The placement position of the injection port 25A and the discharge port 27A can be located on the same side of the plate body 21, and further, the placement position is located on the same side as the signal port 15, thereby simultaneously injecting fuel. Alternatively, it is possible to achieve the convenience of connection such as discharge and electrical connection.

注入流路25と排出流路27は、各槽体23A、23Bの下方と上方にそれぞれ配置され、また、注入流路25と排出流路27の構造が特殊な流路配置、及び、流路切断面寸法を形成することで燃料がスムーズ、且つ、均等に注入口25Aから注入流路25を流動して更に各槽体23A、23Bに流入することができる。更に、上、下2枚の燃料電池板1の電気化学的反応を経て発生した生成物が、スムーズ、且つ、均等に各槽体23A、23Bから排出流路27に流入し、更に排出口27Aへ流動して外部に排出することができる。   The injection channel 25 and the discharge channel 27 are respectively disposed below and above the tank bodies 23A and 23B, and the structure of the injection channel 25 and the discharge channel 27 is a special channel arrangement, and the channel By forming the cut surface dimensions, the fuel can flow smoothly and evenly from the injection port 25A through the injection flow path 25 and further flow into the tank bodies 23A and 23B. Further, the products generated through the electrochemical reaction of the upper and lower two fuel cell plates 1 smoothly and evenly flow from the respective tank bodies 23A, 23B to the discharge flow path 27, and further to the discharge port 27A. Can be discharged to the outside.

前記の各槽体23A、23Bの底面において、例えば中央部のような適切な場所から上方に向かって支持ブロック29を突起形成し、支持ブロック29の高度は、槽体23A、23Bの側辺高度とほぼ近いものとし、その高度程度を例えば同高度、或いは、略凸起とすることができる。各支持ブロック29が燃料電池板1の基板11流路板2の表面に貼着する時、これら支持ブロック29は、対応するこれら膜電極接合体12をそれぞれ支え、これによりこれら膜電極接合体12が燃料電池の反応で熱の発生が起こり槽体23A、23Bが膨張することによって機能が低下することを避けることができる。   On the bottom surface of each of the tank bodies 23A and 23B, for example, a support block 29 is formed to project upward from an appropriate place such as a central portion, and the height of the support block 29 is the side height of the tank bodies 23A and 23B. The altitude level can be, for example, the same altitude or substantially raised. When each support block 29 is attached to the surface of the substrate 11 flow path plate 2 of the fuel cell plate 1, these support blocks 29 support the corresponding membrane electrode assemblies 12 respectively, thereby the membrane electrode assemblies 12 However, it can be avoided that heat is generated by the reaction of the fuel cell and the function is deteriorated due to expansion of the tank bodies 23A and 23B.
