しかしながら、上述した従来構造の燃料電池モジュールにおいては、次のような問題が指摘されている。
すなわち、セルチューブ２の端部から集電電極３までの集電構造が複雑であり、絶縁部材８を含めて部品点数が多いという問題を有している。このように複雑で部品点数の多い集電構造は、組立工数が増大するだけでなく、品質管理や信頼性確保を困難にする。このため、簡単な構造で部品点数を低減できる集電構造を有する燃料電池モジュールが望まれている。
本発明は、上記の事情に鑑みてなされたものであり、その目的とするところは、簡単な構造で部品点数を低減できる集電構造の燃料電池モジュールを提供することにある。 However, the following problems have been pointed out in the fuel cell module having the conventional structure described above.
That is, the current collecting structure from the end of the cell tube 2 to the current collecting electrode 3 is complicated, and the number of parts including the insulating member 8 is large. Such a complicated current collection structure with a large number of parts not only increases the number of assembly steps but also makes it difficult to ensure quality control and ensure reliability. Therefore, a fuel cell module having a current collecting structure that can reduce the number of parts with a simple structure is desired.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fuel cell module having a current collecting structure capable of reducing the number of parts with a simple structure.

本発明は、上記の課題を解決するため、下記の手段を採用した。
本発明に係る燃料電池モジュールは、発電室内に配列された複数のセルチューブが燃料及び空気の供給を受けて発電する固体酸化物形の燃料電池モジュールにおいて、前記セルチューブで発電した電力を集電電極に集める集電が、前記発電室から分割された非発電領域内に位置している前記セルチューブの端部に被せた集電キャップと、前記集電電極に連結された少なくとも一以上からなる集電板との間を少なくとも１本以上の集電線で接続してなされ、
前記集電線の一端が少なくとも一以上からなる前記セルチューブに保持された前記集電キャップに接続され、かつ、前記集電線の他端が前記集電板に固定されていることを特徴とするものである。 In order to solve the above problems, the present invention employs the following means.
A fuel cell module according to the present invention is a solid oxide fuel cell module in which a plurality of cell tubes arranged in a power generation chamber are supplied with fuel and air to generate power, and collects power generated by the cell tubes. A current collecting collected on the electrode is composed of a current collecting cap placed on an end of the cell tube located in a non-power generation region divided from the power generation chamber, and at least one connected to the current collecting electrode. It is made by connecting at least one current collector between the current collector plates,
One end of the current collecting wire is connected to the current collecting cap held by the cell tube made of at least one or more, and the other end of the current collecting wire is fixed to the current collecting plate. It is.

このような燃料電池モジュールによれば、セルチューブで発電した電力を集電電極に集める集電が、発電室から分割された非発電領域内に位置しているセルチューブの端部に被せた集電キャップと、集電電極に連結された少なくとも一以上からなる集電板との間を少なくとも１本以上の集電線で接続してなされ、集電線の一端が少なくとも一以上からなるセルチューブに保持された集電キャップに接続され、かつ、集電線の他端が集電板に固定されているので、セルチューブからの集電構造を簡素化することができる。すなわち、従来構造の集電用端子、ブスバー及び絶縁管が不要になるか、あるいは必要数が減少するので、部品点数を低減した簡素な集電構造となる。   According to such a fuel cell module, the current collecting that collects the electric power generated by the cell tube at the current collecting electrode covers the end of the cell tube located in the non-power generation region divided from the power generation chamber. At least one current collector is connected between the current cap and at least one current collector plate connected to the current collector electrode, and one end of the current collector is held by at least one cell tube Since the other end of the current collector is connected to the current collector cap and the other end of the current collector is fixed to the current collector plate, the current collection structure from the cell tube can be simplified. That is, since the current collecting terminals, bus bars and insulating pipes of the conventional structure are not required or the required number is reduced, a simple current collecting structure with a reduced number of parts is obtained.

上述した本発明の燃料電池モジュールによれば、簡単な構造で部品点数を低減した集電構造の燃料電池モジュールを提供することができる。このため、本発明の燃料電池モジュールは、集電構造の組立工数が減少するだけでなく、品質管理や信頼性確保も容易になるという顕著な効果が得られる。   According to the fuel cell module of the present invention described above, it is possible to provide a fuel cell module having a current collecting structure with a simple structure and a reduced number of parts. For this reason, the fuel cell module of the present invention not only reduces the number of assembly steps of the current collecting structure, but also has a remarkable effect that quality control and reliability are facilitated.

以下、本発明に係る燃料電池モジュールの一実施形態を図面に基づいて説明する。
図１に示す実施形態において、燃料電池モジュール１０は、発電室１内に並列に設置された複数のセルチューブ２が燃料（天然ガス、石油、メタノール、石炭ガス化ガス等）及び空気の供給を受けて発電する固体酸化物形燃料電池（ＳＯＦＣ）である。
燃料電池モジュール１０の集電構造は、管板１ａにより仕切られて発電室１の上部に形成された非発電領域１１に配置されている。この集電構造は、複数あるセルチューブ２内の燃料電池セル（不図示）により発電された電力を、正負一対の集電電極３に集めて外部に供給するためのものである。 Hereinafter, an embodiment of a fuel cell module according to the present invention will be described with reference to the drawings.
In the embodiment shown in FIG. 1, in the fuel cell module 10, a plurality of cell tubes 2 installed in parallel in the power generation chamber 1 supply fuel (natural gas, petroleum, methanol, coal gasification gas, etc.) and air. It is a solid oxide fuel cell (SOFC) that receives and generates electricity.
The current collecting structure of the fuel cell module 10 is arranged in a non-power generation region 11 formed in the upper part of the power generation chamber 1 by being partitioned by a tube plate 1a. This current collection structure is for collecting electric power generated by fuel cells (not shown) in a plurality of cell tubes 2 in a pair of positive and negative current collecting electrodes 3 and supplying them to the outside.

セルチューブ２の上端部には、集電線５の一端を通電可能に保持する集電キャップ４を備えている。この集電キャップ４は、発電室１から非発電領域１１に突出するセルチューブ２の上端部に被せて取り付けられている。
集電線５の他端は、集電電極３に通電可能に連結された集電板２０に固定されている。この集電板２０としては、水蒸気酸化等に対して可逆的な特性を示し、酸化皮膜が形成されて抵抗が増大することが少ない、たとえばニッケルやニッケルクラッド材からなる板が好適である。 The upper end of the cell tube 2 is provided with a current collecting cap 4 that holds one end of the current collecting wire 5 so as to be energized. The current collecting cap 4 is attached over the upper end portion of the cell tube 2 protruding from the power generation chamber 1 to the non-power generation region 11.
The other end of the current collecting wire 5 is fixed to a current collecting plate 20 connected to the current collecting electrode 3 so as to be energized. The current collector plate 20 is preferably a plate made of nickel or a nickel clad material, for example, which exhibits reversible characteristics with respect to steam oxidation or the like and is less likely to increase resistance due to the formation of an oxide film.

ここで、集電板２０と集電電極３との連結構造について、一例を示して説明する。
図示の連結構造は、集電電極３の下端部側にネジ部３ａが設けられている。集電板２０に集電電極３を固定する部分は、集電板２０の両面をニッケル材の補助部材３ｂで挟持した状態とし、３部材に連通する貫通孔に集電電極３のネジ部３ａを通した後にナット３ｃを締め込んで固定する。なお、図中の符号８は、上述した連結構造部の上方を覆う筒状の絶縁材である。 Here, a connection structure between the current collecting plate 20 and the current collecting electrode 3 will be described with reference to an example.
In the illustrated connecting structure, a screw portion 3 a is provided on the lower end side of the collecting electrode 3. The portion for fixing the current collecting electrode 3 to the current collecting plate 20 is a state in which both surfaces of the current collecting plate 20 are sandwiched between auxiliary members 3b made of nickel, and the threaded portion 3a of the current collecting electrode 3 is inserted into a through hole communicating with the three members. After passing, the nut 3c is tightened and fixed. In addition, the code | symbol 8 in a figure is a cylindrical insulating material which covers the upper direction of the connection structure part mentioned above.

上述した構成の集電構造は、集電板２０を介して各セルチューブ２から集電するので、従来の集電構造と比較して部品点数を低減した簡素な構造となる。具体的には、図２に示す従来構造の集電用ブスバー６、集電用端子７をなくすとともに、絶縁材料８の部品点数を低減して簡素化した構造となり、従って、集電構造の組立工数を低減できるとともに、品質管理や信頼性確保が容易になる。   Since the current collecting structure having the above-described configuration collects current from each cell tube 2 via the current collecting plate 20, it has a simple structure with a reduced number of parts compared to the conventional current collecting structure. Specifically, the current collecting bus bar 6 and the current collecting terminal 7 shown in FIG. 2 are eliminated, and the number of parts of the insulating material 8 is reduced, resulting in a simplified structure. Man-hours can be reduced, and quality control and reliability can be easily secured.

このように、本発明の燃料電池モジュール１０は、簡単な構造で部品点数を低減した集電構造となるので、集電構造の組立工数が減少するとともに、品質管理や信頼性確保も容易になる。
なお、本発明は上述した実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において適宜変更することができる。 As described above, the fuel cell module 10 of the present invention has a current collection structure with a simple structure and a reduced number of parts. Therefore, the number of assembly steps of the current collection structure is reduced, and quality control and reliability are easily ensured. .
In addition, this invention is not limited to embodiment mentioned above, In the range which does not deviate from the summary of this invention, it can change suitably.
