Description
【考案の詳細な説明】
本考案は燃料または酸化剤が発電セル、循環ポンプおよ
びガス冷却器を含む循環回路を循環する形式の燃料電池
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fuel cell of the type in which fuel or oxidant is circulated through a circulation circuit that includes a power generation cell, a circulation pump, and a gas cooler.
この種の燃料電池において発電の際主伐する水を除去す
るために、たとえば特開昭４９−１２１９３峰にて示さ
れる如き構造が有効である□ことが実証されている。It has been proven that a structure as shown in, for example, Japanese Patent Laid-Open No. 12193-1983 is effective for removing water that is removed during power generation in this type of fuel cell.
この公知の構造の要部は第１図に示すように、発電セル
１、ガス冷却器２、およびガス循環ポンプ３からなる循
環回路であり、かかる循環回路がたとえば水素−酸素形
燃料電池であれば燃料としての水素ガスおよび酸化剤と
しての酸素ガス用に別々に設けられている。As shown in FIG. 1, the main part of this known structure is a circulation circuit consisting of a power generation cell 1, a gas cooler 2, and a gas circulation pump 3. For example, separate units are provided for hydrogen gas as a fuel and oxygen gas as an oxidizing agent.
この他に電解液の循環系が設けられるが、本考案に直接
関係がないため図示を省略しである。In addition, an electrolyte circulation system is provided, but it is not shown because it is not directly related to the present invention.
発電セル１で生皮された水は循環ガス内へ蒸発し、循環
ガスに随伴してガス冷却器２へ運ばれそこで凝縮されて
生成水タンク７に溜まる。The water raw in the power generation cell 1 is evaporated into the circulating gas, carried along with the circulating gas to the gas cooler 2, where it is condensed and stored in the produced water tank 7.
ところでガス循環ポンプ３より吐出された循環ガスの中
にはガス冷却器出口温度で飽和した水蒸気が含まれてい
る。By the way, the circulating gas discharged from the gas circulation pump 3 contains water vapor saturated at the gas cooler outlet temperature.
この循環ガスの温度が管外部の大気温度より高くかつ管
を大気から完全に断熱できない場合には、ガス循環ポン
プ３と発電セル１とを結ぶ管４め途中で水蒸気が凝縮し
、管４の底部５に溜まることになる。If the temperature of this circulating gas is higher than the atmospheric temperature outside the tube and the tube cannot be completely insulated from the atmosphere, water vapor will condense in the middle of the tube 4 that connects the gas circulation pump 3 and the power generation cell 1. It will accumulate on the bottom 5.
この状態が続くと、ガス循環回路の抵抗が増加しガス循
環流量が減少することになって好ましくない。If this state continues, the resistance of the gas circulation circuit will increase and the gas circulation flow rate will decrease, which is not preferable.
このような凝縮水の溜り湯は第１図の５で示す位置に限
らず、たとえば管４の途中の分岐管その他においても生
じ得るが、ガス循環ポンプ３から管４への立上り部分ま
でにおける水の滞溜が最も問題となる。Such pooling of condensed water is not limited to the location shown by 5 in FIG. The biggest problem is the accumulation of
そこで本考案はガス循環系の循環ポンプ出口から管の立
上り部分までのところで生じた凝縮水を簡単に取除いて
、燃料電池の安定な運転を可能にすることを目的とする
。Therefore, the object of the present invention is to easily remove the condensed water generated from the circulation pump outlet of the gas circulation system to the rising part of the pipe, thereby enabling stable operation of the fuel cell.
この目的は本考案によればガス循環ポンプの出口と管の
立上り部分との間の部分と生成水タンクとの間を細い配
管にて結合することにより遠戚される。According to the invention, this purpose is distantly achieved by connecting the part between the outlet of the gas circulation pump and the rising part of the pipe and the produced water tank with a thin pipe.
この配管は凝縮水を導くだけのものであるから細いもの
で良く、この配管を設けることによる発電セル内の循環
ガスの減少は実際上無視できる。Since this piping is only for guiding condensed water, it may be thin, and the reduction in circulating gas within the power generation cell due to the provision of this piping can be practically ignored.
第２図は本考案の実施例を示すもので、ガス冷却器２の
下部の生成水タンク７と管４の底部５との間を細い配管
６で結合したものである。FIG. 2 shows an embodiment of the present invention, in which a produced water tank 7 at the bottom of the gas cooler 2 and the bottom 5 of the pipe 4 are connected by a thin pipe 6.
管４の内圧はガス循環ポンプ３の吐出圧となっており、
生成水タンクの内圧はガス循環ポンプ３の吸込圧となっ
ているから、管４の底部５に溜まる凝縮水は配管６を通
って生成水タンクへ戻されることになる。The internal pressure of the pipe 4 is the discharge pressure of the gas circulation pump 3,
Since the internal pressure of the produced water tank is the suction pressure of the gas circulation pump 3, the condensed water collected at the bottom 5 of the pipe 4 is returned to the produced water tank through the pipe 6.
凝縮水が無いか有っても少ない場合には、ガス循環ポン
プ３より吐出されたガスの一部もガス冷却器へ戻される
ことになるが、配管６の径は管４の径に比して十分細い
もので良いため、ガス冷却器へ戻される量は循環流量に
比してきわめて少なく実際上無視できる。If there is no condensed water or there is only a small amount of condensed water, part of the gas discharged from the gas circulation pump 3 will also be returned to the gas cooler, but the diameter of the pipe 6 is smaller than the diameter of the pipe 4. Since the flow rate may be sufficiently thin, the amount returned to the gas cooler is extremely small compared to the circulating flow rate and can be ignored in practice.
このように本考案によれば、たとえガス冷却器出口温度
が大気温度よりも高かったとしても、ガス循環系配管を
完全断熱することなく、かつ特別な凝縮水分離器を設け
ることなしに既設の循環ポンプを応用して燃料電池発電
装置を常に安定に運転することが可能となる。In this way, according to the present invention, even if the gas cooler outlet temperature is higher than the atmospheric temperature, the existing gas circulation system piping can be completely insulated and the existing condensed water separator can be used. By applying a circulation pump, it becomes possible to always operate the fuel cell power generation device stably.
