Description

本発明は、固体高分子形燃料電池発電システムに関し、特に、水素ガスを燃料ガスとして用いる場合や、酸素ガスを酸化ガスとして用いる場合に適用すると、極めて有効である。 The present invention relates to a polymer electrolyte fuel cell power generation system, and is particularly effective when applied to a case where hydrogen gas is used as a fuel gas or an oxygen gas is used as an oxidizing gas.

固体高分子形燃料電池は、プロトン伝導性を有する固体高分子電解質膜を導電性及びガス透過性を有する燃料極及び酸化極で挟んだセルと、水素ガスを含有する燃料ガスの流路及び酸素ガスを含有する酸化ガスの流路をそれぞれ形成されると共に導電性を有するセパレータとを交互に複数積層して積層方向両端側を一対のエンドフランジで挟み込んで構成されている。 A polymer electrolyte fuel cell includes a cell in which a solid polymer electrolyte membrane having proton conductivity is sandwiched between a fuel electrode and an oxide electrode having conductivity and gas permeability, a flow path of fuel gas containing hydrogen gas, and oxygen Each of the gas-containing oxidizing gas flow paths is formed, and a plurality of conductive separators are alternately stacked, and both ends in the stacking direction are sandwiched between a pair of end flanges.

このような固体高分子形燃料電池を備えた固体高分子形燃料電池発電システムにおいては、固体高分子形燃料電池の上記エンドフランジに形成された燃料ガス受入口及び酸化ガス受入口から燃料ガス及び酸化ガスをそれぞれ供給すると、当該燃料ガス及び当該酸化ガスが各上記セパレータの各上記流路内をそれぞれ流通して、前記水素ガス及び前記酸素ガスが上記セルで電気化学的に反応して電力を取り出すことができるようになっている。 In the polymer electrolyte fuel cell power generation system provided with such a polymer electrolyte fuel cell, the fuel gas and the oxidizing gas inlet are formed in the end flange of the polymer electrolyte fuel cell. When the oxidizing gas is supplied, the fuel gas and the oxidizing gas respectively flow through the flow paths of the separators, and the hydrogen gas and the oxygen gas react electrochemically in the cells to generate power. It can be taken out.

そして、使用済みの上記燃料ガス及び上記酸化ガスは、上記電気化学反応に伴って生じた生成水と共に各上記流路を流通して、上記エンドフランジに形成された燃料ガス排出口及び酸化ガス排出口から外部へそれぞれ排出されるようになっている。 The spent fuel gas and the oxidizing gas are circulated through the flow paths together with the generated water generated by the electrochemical reaction, and the fuel gas outlet and the oxidizing gas exhaust formed in the end flange. It is discharged from the outlet to the outside.

ここで、例えば、水素ガスそのものを燃料ガスとして使用する場合や酸素ガスそのものを酸化ガスとして使用する場合には、上記ガス排出口にドレンセパレータを介してブロアやエジェクタ等のガス循環装置のガス受入口を接続すると共に、当該ガス循環装置のガス送出口を上記ガス受入口に接続することにより、上記生成水と上記電気化学反応に供されなかった水素ガス及び酸素ガスとを上記ガス排出口から排出させてドレンセパレータで分離させた後、当該ガスを上記ガス受入口に戻して新たな上記ガスと共に再び供給するようにして、これらガスを有効利用するようにしている。 Here, for example, when hydrogen gas itself is used as a fuel gas or oxygen gas itself is used as an oxidizing gas, the gas outlet of the gas circulation device such as a blower or an ejector is connected to the gas discharge port via a drain separator. By connecting the inlet and connecting the gas outlet of the gas circulation device to the gas inlet, the generated water and the hydrogen gas and oxygen gas that have not been subjected to the electrochemical reaction are discharged from the gas outlet. After being discharged and separated by a drain separator, the gas is returned to the gas inlet and supplied again with the new gas so that these gases can be used effectively.

ところが、このようにして水素ガスそのものを燃料ガスとして使用するときや酸素ガスそのものを酸化ガスとして使用するときには、前述したようなガス循環装置を利用するため、余計に電力を消費してしまい、発電システム全体の電力効率が悪くなってしまっている。 However, when hydrogen gas itself is used as a fuel gas or oxygen gas itself is used as an oxidizing gas in this way, the above-described gas circulation device is used, which consumes extra power and generates power. The power efficiency of the entire system has deteriorated.

そこで、例えば、下記特許文献１等においては、セルとセパレータとを交互に複数積層したサブスタックを、燃料ガス及び酸化ガスの流通経路を直列ループ状にするように複数（例えば２つ）接続して固体高分子形燃料電池を構成し、燃料ガス供給手段及び酸化ガス供給手段を各サブスタックの燃料ガス受入口及び酸化ガス受入口にそれぞれ接続して、これらサブスタック同士の間の上記ガスの流通経路に気液分離手段をそれぞれ配設し、上記ガス供給手段と各サブスタックの上記ガス受入口との間をそれぞれ切断又は接続する燃料ガス用上流位置切換手段及び酸化ガス用上流位置切換手段を設けると共に、上記サブスタック同士の間の上記ガスの流通経路をそれぞれ切断又は接続する燃料ガス用下流位置切換手段及び酸化ガス用下流位置切換手段を設け、例えば、所定時間運転したら、上記ガスの流通方向上流側及び下流側に位置するサブスタックをそれぞれ切り換えるように上記位置切換手段をそれぞれ作動させることにより、前述したようなガス循環装置がなくても上記スタックから水分を排出しながら当該水分で上記ガスを加湿して有効利用できるようにし、システム全体の電力効率を向上させるようにした固体高分子形燃料電池発電システムを提案している。 Thus, for example, in Patent Document 1 below, a plurality of (for example, two) sub-stacks in which a plurality of cells and separators are alternately stacked are connected so that the flow paths of the fuel gas and the oxidizing gas are in a series loop shape. The polymer electrolyte fuel cell is configured, and the fuel gas supply means and the oxidizing gas supply means are connected to the fuel gas inlet and the oxidizing gas inlet of each sub-stack, respectively. Gas gas-liquid separation means is disposed in the flow path, and the fuel gas upstream position switching means and the oxidizing gas upstream position switching means for cutting or connecting between the gas supply means and the gas inlets of the sub-stacks, respectively. And a downstream position switching means for fuel gas and a downstream position switch for oxidizing gas for cutting or connecting the gas flow paths between the sub-stacks, respectively. For example, after operating for a predetermined time, the gas switching device as described above can be operated by operating the position switching means so as to switch the sub-stacks positioned upstream and downstream in the gas flow direction. We have proposed a polymer electrolyte fuel cell power generation system that improves the power efficiency of the entire system by allowing the gas to be humidified and effectively used without draining the moisture from the stack. .

しかしながら、上記特許文献１等に記載されている上記固体高分子形燃料電池発電システムにおいては、前記ガスの供給源から送給される前記ガスが乾燥していることから、前記サブスタックの前記セルの前記固体高分子電解質膜の前記ガス受入口側の含水率が低下して乾燥しやすく、長期間にわたって連続して発電運転を行なっていくと、当該サブスタックに供給する当該ガスの流量や流速等の発電運転条件によっては、当該固体高分子電解質膜の前記ガス受入口側の劣化を引き起こして当該固体高分子電解質膜の寿命を低下させてしまう可能性があった。 However, in the polymer electrolyte fuel cell power generation system described in Patent Document 1 and the like, since the gas supplied from the gas supply source is dry, the cell of the sub-stack When the moisture content on the gas inlet side of the solid polymer electrolyte membrane of the solid polymer electrolyte membrane decreases and is easily dried, and the power generation operation is performed continuously over a long period of time, the flow rate and flow rate of the gas supplied to the substack Depending on the power generation operation conditions such as the above, there is a possibility that the deterioration of the solid polymer electrolyte membrane on the gas inlet side is caused and the life of the solid polymer electrolyte membrane is shortened.

このようなことから、本発明は、長期間にわたって連続して発電運転を行なっても、固体高分子電解質膜の寿命の低下を大幅に抑制することができる固体高分子形燃料電池発電システムを提供することを目的とする。 For this reason, the present invention provides a solid polymer fuel cell power generation system capable of greatly suppressing a decrease in the life of the solid polymer electrolyte membrane even when the power generation operation is continuously performed for a long period of time. The purpose is to do.

In this embodiment, since the fuel gas system and the oxidant gas system operate in the same manner, the operation of the fuel gas system will be described below to avoid complication of the description. It shall be replaced with an explanation of operation.

前記ガス供給源１２１から前記ガス１を送給すると共に、前記制御装置１６０を作動させると、当該制御装置１６０は、前記バルブ１４０Ｆ〜１４０Ｌを閉鎖すると共に前記バルブ１４０Ａ〜１４０Ｅを開放するように当該バルブ１４０Ａ〜１４０Ｌを制御する（図３Ａ参照）。 When the gas 1 is supplied from the gas supply source 121 and the control device 160 is operated, the control device 160 closes the valves 140F to 140L and opens the valves 140A to 140E. The valves 140A to 140L are controlled (see FIG. 3A).

これにより、前記ガス供給源１２１からの前記ガス１が、前記ライン１４１を流通し、前記ドレンセパレータ１２２を経由して前記第一のサブスタック１１１の前記ガス流路の一方の口へ供給されて、各前記セパレータの各前記流路内を流通することにより、当該第一のサブスタック１１１において、電気化学反応を生じて電力を発生する。 As a result, the gas 1 from the gas supply source 121 flows through the line 141 and is supplied to one port of the gas flow path of the first sub stack 111 via the drain separator 122. By flowing through each flow path of each separator, an electrochemical reaction is generated in the first sub-stack 111 to generate electric power.

そして、使用済みの上記ガス１（約１／２を使用された残りの約１／２）が、上記電気化学反応に伴って生じた水３と共に各上記流路を流通して、前記ガス流路の他方の口から排出され、前記ライン１４２を流通して前記ドレンセパレータ１２３で当該水３を分離された後、前記ドレンセパレータ１２４を経由して前記第二のサブスタック１１２の前記ガス流路の一方の口へ供給されて、各前記セパレータの各前記流路内を流通することにより、当該第二のサブスタック１１２において、電気化学反応を生じて電力を発生する。 Then, the used gas 1 (the remaining about 1/2 using about 1/2) flows through each flow path together with the water 3 generated by the electrochemical reaction, and the gas flow After being discharged from the other port of the passage and flowing through the line 142 to separate the water 3 by the drain separator 123, the gas flow path of the second sub-stack 112 via the drain separator 124 In the second sub-stack 112, an electric power is generated by generating an electrochemical reaction in the second sub-stack 112.

このとき、前記第一のサブスタック１１１においては、前記ガス供給源１２１からの前記ガス１がそのままの状態で前記ガス流路の一方の口に供給されることから、前記セルの前記固体高分子電解質膜の、当該ガス流路の一方の口寄り部分が乾燥しやすくなると共に、前記第二のサブスタック１１２においては、前記ガス１（残りの約１／２）のほとんどが消費されて、前記ガス流路の他方の口から排出されるガスがほとんどないので、上記電気化学反応に伴って生じた水３が、前記ガス流路内の他方の口寄りに次第に滞留し始め、発電性能が低下するようになる。 At this time, in the first sub-stack 111, the gas 1 from the gas supply source 121 is supplied as it is to one port of the gas flow path, so that the solid polymer of the cell The part near the mouth of the gas flow path of the electrolyte membrane is easily dried, and in the second sub-stack 112, most of the gas 1 (about the remaining half) is consumed, Since there is almost no gas discharged from the other port of the gas flow path, the water 3 generated by the electrochemical reaction gradually starts to stay near the other port in the gas flow path, and the power generation performance decreases. To come.

ここで、前記制御装置１６０は、前記タイマからの情報に基づいて、予め設定された運転時間（例えば２分間）が経過すると、前記バルブ１４０Ｂ，１４０Ｅ〜１４０Ｈ，１４０Ｊ，１４０Ｌを開放すると共に、前記バルブ１４０Ａ，１４０Ｃ，１４０Ｄ，１４０Ｉ，１４０Ｋを閉鎖するように、当該バルブ１４０Ａ〜１４０Ｌを制御する（図３Ｂ参照）。 Here, the control device 160 opens the valves 140B, 140E to 140H, 140J, and 140L when a preset operation time (for example, 2 minutes) elapses based on information from the timer, and The valves 140A to 140L are controlled so as to close the valves 140A, 140C, 140D, 140I, and 140K (see FIG. 3B).

つまり、前記制御装置１４０は、前記ガス供給源１２１からの前記ガス１を、当該ガス１の流通方向下流側に位置する前記第二のサブスタック１１２の前記ガス流路の他方の口、すなわち、当該ガス１の流通方向下流側の口から当該第二のサブスタック１１２の当該ガス流路に供給すると共に、当該第二のサブスタック１１２の当該ガス流路を流通した前記ガス１を、当該ガス１の流通方向上流側に位置していた前記第一のサブスタック１１１の前記ガス流路に供給するように、前記バルブ１４０Ａ〜１４０Ｌを制御するのである。 That is, the control device 140 transfers the gas 1 from the gas supply source 121 to the other port of the gas flow path of the second sub-stack 112 located downstream in the flow direction of the gas 1, that is, The gas 1 supplied to the gas flow path of the second sub-stack 112 from the downstream port in the flow direction of the gas 1 and the gas 1 flowing through the gas flow path of the second sub-stack 112 is supplied to the gas The valves 140 A to 140 L are controlled so as to be supplied to the gas flow path of the first sub-stack 111 located on the upstream side of the one distribution direction.

これにより、前記ガス供給源１２１からの全流量の前記ガス１が、前記ライン１４３を流通し、前記ドレンセパレータ１２５を経由して前記第二のサブスタック１１２の前記ガス流路の他方の口へ供給されて、各前記セパレータの各前記流路内を流通することにより、当該第二のサブスタック１１２において、当該流路内に滞留している水３を押し出しつつ加湿されながら、電気化学反応を生じて電力を発生する。 As a result, the gas 1 having the entire flow rate from the gas supply source 121 flows through the line 143 and passes through the drain separator 125 to the other port of the gas flow path of the second sub-stack 112. By supplying and flowing through each flow path of each separator, the second sub-stack 112 performs an electrochemical reaction while being humidified while pushing out the water 3 remaining in the flow path. To generate power.

そして、加湿された使用済みの上記ガス１（約１／２を使用された残りの約１／２）が、当該電気化学反応に伴って新たに生じた水３及び滞留していた上記水３と共に各上記流路を流通して、前記ガス流路の一方の口から排出され、前記ライン１４２を流通して前記ドレンセパレータ１２４で当該水３を分離された後、前記ライン１４６及び前記ライン１４４を介して前記ライン１４１に流入し、前記ドレンセパレータ１２２を経由して前記第一のサブスタック１１１の前記ガス流路の一方の口へ供給され、各前記セパレータの各前記流路内を流通することにより、当該第一のサブスタック１１１において、前記セルの前記固体高分子電解質膜の、当該ガス流路の一方の口寄り部分を含めた全体を加湿しつつ、電気化学反応を生じて電力を発生する。 The humidified spent gas 1 (about 1/2 of the remaining about 1/2 used) is water 3 newly generated in association with the electrochemical reaction and the water 3 that has been retained. In addition, the water circulates through each of the flow paths and is discharged from one port of the gas flow path. After the water 3 is separated by the drain separator 124 through the line 142, the lines 146 and 144 Flows into the line 141 through the drain separator 122 and is supplied to one port of the gas flow path of the first sub-stack 111 and flows through the flow paths of the separators. As a result, in the first sub-stack 111, the entire solid polymer electrolyte membrane of the cell including the portion near one mouth of the gas flow path is humidified, and an electrochemical reaction occurs to generate electric power. Departure To.

このとき、前記第二のサブスタック１１２においては、前記供給源１２１からの全流量の前記ガス１が供給されるようになるので、前記流路内に滞留している水３が押し出されて、電気化学反応に伴って新たに生じた水３と共に排出されることから、発電性能の低下が防止されるようになると共に、前記第一のサブスタック１１１においては、前記第二のサブスタック１１２で加湿された前記ガス１が供給されるので、前記セルの前記固体高分子電解質膜の、当該ガス流路の一方の口寄り部分を含めた全体が加湿されることから、当該固体高分子膜の、当該ガス流路の一方の口寄り部分を含めた全体の劣化が抑制されるものの、今度は、新たに、上記第二のサブスタック１１２において、前記ガス供給源１２１からの前記ガス１がそのままの状態で前記ガス流路の他方の口に供給されることから、前記セルの前記固体高分子電解質膜の、当該ガス流路の他方の口寄り部分が乾燥しやすくなると共に、上記第一のサブスタック１１１において、供給された前記ガス１のほとんどが消費されて、前記ガス流路の他方の口から排出されるガスがほとんどなくなることから、上記電気化学反応に伴って生じた水３が、前記ガス流路内の他方の口寄りに次第に滞留し始め、発電性能が低下するようになる。 At this time, in the second sub-stack 112, the gas 1 having the entire flow rate from the supply source 121 is supplied, so that the water 3 staying in the flow path is pushed out, Since it is discharged together with the water 3 newly generated in accordance with the electrochemical reaction, it is possible to prevent the power generation performance from being deteriorated, and in the first substack 111, the second substack 112 Since the humidified gas 1 is supplied, the entire solid polymer electrolyte membrane of the cell including the portion near one mouth of the gas flow path is humidified. Although the entire deterioration including the portion near one mouth of the gas flow path is suppressed, the gas 1 from the gas supply source 121 is newly added as it is in the second sub-stack 112. of Is supplied to the other port of the gas flow channel, the portion of the solid polymer electrolyte membrane of the cell that is close to the other port of the gas flow channel can be easily dried, and the first sub In the stack 111, most of the supplied gas 1 is consumed and almost no gas is discharged from the other port of the gas flow path, so that the water 3 generated by the electrochemical reaction is It gradually begins to stay near the other port in the gas flow path, and the power generation performance decreases.

ここで、前記制御装置１６０は、前記タイマからの情報に基づいて、予め設定された運転時間（例えば、２分間）が経過すると、前記バルブ１４０Ｂ，１４０Ｃ，１４０Ｅ，１４０Ｈ，１４０Ｊ〜１４０Ｌを開放すると共に、前記バルブ１４０Ａ，１４０Ｄ，１４０Ｆ，１４０Ｇ，１４０Ｉを閉鎖するように、当該バルブ１４０Ａ〜１４０Ｌを制御する（図３Ｃ参照）。 Here, the control device 160 opens the valves 140B, 140C, 140E, 140H, and 140J to 140L when a preset operation time (for example, 2 minutes) elapses based on information from the timer. At the same time, the valves 140A to 140L are controlled so as to close the valves 140A, 140D, 140F, 140G, and 140I (see FIG. 3C).

つまり、前記制御装置１６０は、前記ガス供給源１２１からの全流量の前記ガス１の供給先を、当該ガス１の流通方向下流側に位置する前記第一のサブスタック１１１の前記ガス流路の他方の口、すなわち、当該ガス１の流通方向下流側の口から当該第一のサブスタック１１２の当該ガス流路に供給すると共に、当該第一のサブスタック１１１の当該ガス流路を流通した前記ガス１を、当該ガス１の流通方向上流側に位置していた前記第二のサブスタック１１２の前記ガス流路に供給するように、前記バルブ１４０Ａ〜１４０Ｌを制御するのである。 That is, the control device 160 supplies the gas 1 having a total flow rate from the gas supply source 121 to the gas flow path of the first sub-stack 111 located downstream in the flow direction of the gas 1. The other port, that is, the gas downstream of the flow direction of the gas 1 is supplied to the gas flow path of the first substack 112 and the gas flow path of the first substack 111 is circulated. The valves 140 A to 140 L are controlled so that the gas 1 is supplied to the gas flow path of the second sub stack 112 located upstream in the flow direction of the gas 1.

これにより、前記ガス供給源１２１からの全流量の前記ガス１が、前記ライン１４３及び前記ライン１４５を介して前記ライン１４２に流入し、前記ドレンセパレータ１２３を経由して前記第一のサブスタック１１１の前記ガス流路の他方の口へ供給されて、各前記セパレータの各前記流路内を流通することにより、当該第一のサブスタック１１１において、当該流路内に滞留している水３を押し出しつつ加湿されながら、電気化学反応を生じて電力を発生する。 As a result, the gas 1 having the entire flow rate from the gas supply source 121 flows into the line 142 via the line 143 and the line 145, and passes through the drain separator 123 to the first sub stack 111. In the first sub-stack 111, the water 3 staying in the flow path is supplied to the other port of the gas flow path and flowing through the flow paths of the separators. While being extruded and humidified, an electrochemical reaction occurs to generate electric power.

そして、使用済みの前記ガス１（約１／２を使用された残りの約１／２）が、上記電気化学反応に伴って新たに生じた水３及び滞留していた上記水３と共に各上記流路を流通して、前記ガス流路の一方の口から排出され、前記ライン１４１を流通して前記ドレンセパレータ１２２で当該水３を分離された後、前記ライン１４４及び前記ライン１４６を介して前記ライン１４２に流入し、前記ドレンセパレータ１２４を経由して前記第二のサブスタック１１２の前記ガス流路の一方の口へ供給され、各前記セパレータの各前記流路内を流通することにより、当該第二のサブスタック１１２において、前記セルの前記固体高分子電解質膜の、当該ガス流路の一方の口寄り部分を含めた全体を加湿しつつ、電気化学反応を生じて電力を発生する。 Then, the used gas 1 (the remaining about ½ of which about ½ is used) is added to each of the above-mentioned water 3 together with the water 3 newly generated in association with the electrochemical reaction and the water 3 that has stayed. After flowing through the flow path and discharged from one port of the gas flow path, the water 3 is separated by the drain separator 122 through the line 141, and then through the line 144 and the line 146. By flowing into the line 142, being supplied to one of the gas flow paths of the second sub-stack 112 via the drain separator 124, and flowing through the flow paths of the separators, In the second sub-stack 112, an electric power is generated by generating an electrochemical reaction while humidifying the entire solid polymer electrolyte membrane of the cell including a portion near one mouth of the gas flow path.

このとき、前記第一のサブスタック１１１においては、前記供給源１２１からの全流量の前記ガス１が供給されるようになるので、前記流路内に滞留している水３が押し出されて、電気化学反応に伴って新たに生じた水３と共に排出されることから、発電性能の低下が防止されるようになると共に、前記第二のサブスタック１１２においては、前記第一のサブスタック１１１で加湿された前記ガス１が供給されるので、前記セルの前記固体高分子電解質膜の、当該ガス流路の一方の口寄り部分を含めた全体が加湿されることから、当該固体高分子膜の、当該ガス流路の一方の口寄り部分を含めた全体の劣化が抑制されるものの、今度は、再び、上記第一のサブスタック１１１において、前記ガス供給源１２１からの前記ガス１がそのままの状態で前記ガス流路の他方の口に供給されることから、前記セルの前記固体高分子電解質膜の、当該ガス流路の他方の口寄り部分が乾燥しやすくなると共に、前記第二のサブスタック１１２において、供給された前記ガス１のほとんどが消費されて、前記ガス流路の他方の口から排出されるガスがほとんどなくなるので、上記電気化学反応に伴って生じた水３が、前記流路内に次第に滞留し始め、発電性能が低下するようになる。 At this time, in the first sub-stack 111, the gas 1 having the entire flow rate from the supply source 121 is supplied, so that the water 3 staying in the flow path is pushed out, Since it is discharged together with the water 3 newly generated along with the electrochemical reaction, it is possible to prevent the power generation performance from being deteriorated, and in the second substack 112, the first substack 111 Since the humidified gas 1 is supplied, the entire solid polymer electrolyte membrane of the cell including the portion near one mouth of the gas flow path is humidified. Although the entire deterioration including the portion near one mouth of the gas flow path is suppressed, the gas 1 from the gas supply source 121 remains in the first sub-stack 111 again. Condition Is supplied to the other port of the gas flow path, the portion of the solid polymer electrolyte membrane of the cell that is close to the other port of the gas flow path can be easily dried, and the second sub-stack. In 112, most of the supplied gas 1 is consumed, and almost no gas is discharged from the other port of the gas flow path, so that the water 3 generated by the electrochemical reaction is removed from the flow path. It gradually begins to stay inside, and the power generation performance decreases.

ここで、前記制御装置１６０は、前記タイマからの情報に基づいて、予め設定された運転時間（例えば、２分間）が経過すると、前記バルブ１４０Ｃ〜１４０Ｈを開放すると共に、前記バルブ１４０Ａ，１４０Ｂ，１４０Ｉ〜１４０Ｌを閉鎖するように、当該バルブ１４０Ａ〜１４０Ｌを制御する（図３Ｄ参照）。 Here, based on information from the timer, the control device 160 opens the valves 140C to 140H and passes the valves 140A, 140B, when a preset operation time (for example, 2 minutes) elapses. The valves 140A to 140L are controlled so as to close the 140I to 140L (see FIG. 3D).

つまり、前記制御装置１６０は、前記ガス供給源１２１からの全流量の前記ガス１の供給先を、当該ガス１の流通方向下流側に位置する前記第二のサブスタック１１２の前記ガス流路の他方の口、すなわち、当該ガス１の流通方向下流側の口から当該第二のサブスタック１１２の当該ガス流路に供給すると共に、当該第二のサブスタック１１２の当該ガス流路を流通した前記ガス１を、当該ガス１の流通方向上流側に位置していた前記第一のサブスタック１１１の前記ガス流路に供給するように、前記バルブ１４０Ａ〜１４０Ｌを制御するのである。 In other words, the control device 160 supplies the supply destination of the gas 1 at the entire flow rate from the gas supply source 121 to the gas flow path of the second sub-stack 112 located downstream in the flow direction of the gas 1. The other port, that is, the gas downstream of the flow direction of the gas 1 is supplied to the gas flow path of the second sub-stack 112 and the gas flow path of the second sub-stack 112 is circulated. The valves 140 A to 140 L are controlled so that the gas 1 is supplied to the gas flow path of the first sub stack 111 located upstream in the flow direction of the gas 1.

これにより、前記ガス供給源１２１からの全流量の前記ガス１が、前記ライン１４３を介して前記ライン１４２に流入し、前記ドレンセパレータ１２５を経由して前記第二のサブスタック１１２の前記ガス流路の他方の口へ供給されて、各前記セパレータの各前記流路内を流通することにより、当該第二のサブスタック１１２において、当該流路内に滞留している水３を押し出しつつ加湿されながら、電気化学反応を生じて電力を発生する。 As a result, the gas 1 having the entire flow rate from the gas supply source 121 flows into the line 142 through the line 143 and flows through the drain separator 125 in the second sub-stack 112. By being supplied to the other port of the path and flowing in each flow path of each separator, the second sub-stack 112 is humidified while pushing out the water 3 staying in the flow path. However, an electrochemical reaction occurs to generate electric power.

そして、使用済みの前記ガス１（約１／２を使用された残りの約１／２）が、上記電気化学反応に伴って新たに生じた水３及び滞留していた上記水３と共に各上記流路を流通して、前記ガス流路の一方の口から排出され、前記ライン１４２を流通して前記ドレンセパレータ１２４で当該水３を分離された後、前記ドレンセパレータ１２３を経由して前記第一のサブスタック１１１の前記ガス流路の他方の口へ供給され、各前記セパレータの各前記流路内を流通することにより、当該第一のサブスタック１１１において、前記セルの前記固体高分子電解質膜の、当該ガス流路の他方の口寄り部分を含めた全体を加湿しつつ、電気化学反応を生じて電力を発生する。 Then, the used gas 1 (the remaining about ½ of which about ½ is used) is added to each of the above-mentioned water 3 together with the water 3 newly generated in association with the electrochemical reaction and the water 3 that has stayed. After flowing through the flow path and discharged from one port of the gas flow path, the water 3 is separated by the drain separator 124 through the line 142, and then through the drain separator 123. The solid polymer electrolyte of the cell in the first substack 111 is supplied to the other port of the gas flow path of one substack 111 and flows through each flow path of each separator. While the whole of the membrane including the portion near the other mouth of the gas flow path is humidified, an electrochemical reaction occurs to generate electric power.

以下、制御装置１４０は、前記タイマからの情報に基づいて、予め設定された運転時間（例えば、２分間）が経過すると、図３Ｅ，図３Ｆ，図３Ｇ，図３Ｈに示すように前記バルブ１４０Ａ〜１４０Ｌの開閉制御を順次行った後、図３Ａに示した前記バルブ１４０Ａ〜１４０Ｌの開閉制御を再び行って、一連の上記バルブ１４０Ａ〜１４０Ｌの開閉制御を繰り返す。 Hereinafter, when a preset operation time (for example, 2 minutes) elapses based on information from the timer, the control device 140, as shown in FIGS. 3E, 3F, 3G, and 3H, the valve 140A. After sequentially performing the opening / closing control of .about.140L, the opening / closing control of the valves 140A-140L shown in FIG. 3A is performed again to repeat the opening / closing control of the series of valves 140A-140L.

これにより、前記固体高分子形燃料電池１１０は、前記ガス供給源１２１からの前記ガス１を、当該ガス１の流通方向下流側に位置する前記第一のサブスタック１１１及び前記第二のサブスタック１１２の一方のサブスタックの前記ガス流路の当該ガス１の流通方向下流側の口から当該一方のサブスタックの当該ガス流路に供給されると共に、当該一方のサブスタックの当該ガス流路を流通した前記ガス１を、前記第一のサブスタック１１１及び前記第二のサブスタック１１２の他方のサブスタックの前記ガス流路に供給されるように定期的に切り換えられるのである。 Thereby, the polymer electrolyte fuel cell 110 uses the first sub-stack 111 and the second sub-stack located on the downstream side in the flow direction of the gas 1 for the gas 1 from the gas supply source 121. 112 is supplied to the gas flow path of the one sub-stack from the port on the downstream side in the flow direction of the gas 1 of the gas flow path of the one sub-stack, and the gas flow path of the one sub-stack The circulated gas 1 is periodically switched so as to be supplied to the gas flow path of the other sub-stack of the first sub-stack 111 and the second sub-stack 112.

このため、本実施形態に係る固体高分子形燃料電池発電システム１００においては、ブロアやエジェクタ等のガス循環装置がなくても、前記サブスタック１１１，１１２内に生成した前記水３を当該サブスタック１１１，１１２内から排出することができるのはもちろんのこと、加湿器等がなくても、前記ガス供給源１２１から送給される前記ガス１を前記サブスタック１１１，１１２内に加湿して供給することができると共に、前記ガス供給源１２１からそのままの状態で前記ガス１を供給される前記サブスタック１１１，１１２の前記ガス流路の口を従来（２箇所）よりも増やすことができるので（４箇所）、前記サブスタック１１１，１１２の前記セルの前記固体高分子電解質膜の、前記ガス流路の口寄り部分の劣化を抑制することができる。 For this reason, in the polymer electrolyte fuel cell power generation system 100 according to the present embodiment, the water 3 generated in the substacks 111 and 112 is generated in the substack without using a gas circulation device such as a blower or an ejector. The gas 1 supplied from the gas supply source 121 is humidified and supplied into the sub-stacks 111 and 112 without need of a humidifier, etc. In addition, the number of gas passage ports of the sub-stacks 111 and 112 to which the gas 1 is supplied as it is from the gas supply source 121 can be increased as compared to the conventional (two locations) ( 4 places), suppressing deterioration of the portion close to the mouth of the gas flow path of the solid polymer electrolyte membrane of the cell of the sub-stacks 111 and 112 Kill.

したがって、本実施形態に係る固体高分子形燃料電池発電システム１００によれば、長期間にわたって連続して発電運転を行なっても、固体高分子電解質膜の寿命の低下を大幅に抑制することができる。 Therefore, according to the polymer electrolyte fuel cell power generation system 100 according to the present embodiment, even if the power generation operation is continuously performed over a long period of time, a decrease in the life of the solid polymer electrolyte membrane can be significantly suppressed. .

（１）燃料ガス用切換時期確認手段や酸化ガス用切換時期確認手段として、前記サブスタックの前記セルの電圧値を計測するセル電圧計測手段を設け、燃料ガス用制御手段や酸化ガス用制御手段が、当該セル電圧計測手段からの情報に基づいて、前記ガス流通方向下流側に位置する前記サブスタックのセル電圧が、予め設定されたセル電圧変化量（例えば、上流側に位置していたときを１として、−０．０２５）になったときに、前記断接手段を制御するようにする（例えば、特開２００２−１５１１２５号公報等に記載されている技術の応用）。 (1) As a fuel gas switching timing confirmation means and an oxidizing gas switching timing confirmation means, cell voltage measurement means for measuring the voltage value of the cell of the sub stack is provided, and the fuel gas control means and the oxidation gas control means are provided. However, based on the information from the cell voltage measuring means, when the cell voltage of the sub stack located downstream in the gas flow direction is set to a preset cell voltage change amount (for example, located upstream) Is set to -0.025), the connection / disconnection means is controlled (for example, application of the technique described in JP-A-2002-151125).

（２）燃料ガス用切換時期確認手段や酸化ガス用切換時期確認手段として、前記サブスタックの前記セルの抵抗値を計測するセル抵抗計測手段を設け、燃料ガス用制御手段や酸化ガス用制御手段が、当該セル抵抗計測手段からの情報に基づいて、前記ガス流通方向下流側に位置する前記サブスタックのセル抵抗が、予め設定されたセル抵抗変化量（例えば、上流側に位置していたときを１として、＋０．０１５）になったときに、前記断接手段を制御するようにする。 (2) As a fuel gas switching timing confirmation means and an oxidizing gas switching timing confirmation means, a cell resistance measurement means for measuring the resistance value of the cell of the sub stack is provided, and the fuel gas control means and the oxidation gas control means are provided. However, based on the information from the cell resistance measuring means, when the cell resistance of the sub stack located on the downstream side in the gas flow direction is set to a preset cell resistance change amount (for example, on the upstream side) When the value becomes +0.015), the connecting / disconnecting means is controlled.

また、前述した実施形態では、水素ガス１そのものを燃料ガスとして使用すると共に、酸素ガス２そのものを酸化ガスとして使用する場合について説明したが、他の実施形態として、例えば、水素ガス１そのものを燃料ガスとして使用すると共に、酸素ガス以外の成分を比較的多く含む酸化ガス（酸素ガス濃度９９％未満、例えば空気等）を使用する場合には、燃料ガス系統のみ前述した実施形態のように構成することや、水素ガス以外の成分を比較的多く含む燃料ガス（水素ガス濃度９９％未満、例えば炭化水素の改質ガス等）を使用すると共に、酸素ガス２そのものを酸化ガスとして使用する場合には、酸化ガス系統のみ前述した実施形態のように構成することも可能である。 In the above-described embodiment, the case where the hydrogen gas 1 itself is used as the fuel gas and the oxygen gas 2 itself is used as the oxidizing gas has been described. However, as another embodiment, for example, the hydrogen gas 1 itself is used as the fuel. When an oxidizing gas (oxygen gas concentration of less than 99%, for example, air) containing a relatively large amount of components other than oxygen gas is used, only the fuel gas system is configured as in the above-described embodiment. In addition, when using a fuel gas containing a relatively large amount of components other than hydrogen gas (hydrogen gas concentration less than 99%, for example, a reformed gas of hydrocarbon, etc.) and using oxygen gas 2 itself as an oxidizing gas, Only the oxidizing gas system can be configured as in the above-described embodiment.

さらに、水素ガス１そのものを燃料ガスとして使用すると共に、酸素ガス２そのものを酸化ガスとして使用する場合であっても、燃料ガス系統及び酸化ガス系統のいずれか一方のみを前述した実施形態のように構成することも可能である。このとき、水素ガス１側よりも酸素ガス２側の方が水３を多く生じやすいため、少なくとも酸化ガス系統を前記した実施形態のように構成することが好ましい。 Further, even when the hydrogen gas 1 itself is used as the fuel gas and the oxygen gas 2 itself is used as the oxidizing gas, only one of the fuel gas system and the oxidizing gas system is used as in the above-described embodiment. It is also possible to configure. At this time, since the oxygen gas 2 side tends to generate more water 3 than the hydrogen gas 1 side, it is preferable to configure at least the oxidizing gas system as in the above-described embodiment.

しかしながら、燃料ガス系統及び酸化ガス系統の両方共に前述した実施形態のように構成すれば、酸化ガス系統側よりも少ないながらも燃料ガス系統側に生じる水３も確実に排出することができると共に、燃料ガス系統側と酸化ガス系統側との間の差圧をできるだけ小さくすることが可能となるので、非常に好ましい。 However, if both the fuel gas system and the oxidant gas system are configured as in the above-described embodiment, the water 3 generated on the fuel gas system side can be reliably discharged while being less than the oxidant gas system side, This is very preferable because the differential pressure between the fuel gas system side and the oxidizing gas system side can be made as small as possible.

本発明に係る固体高分子形燃料電池発電システムは、長期間にわたって連続して発電運転を行なっても、固体高分子電解質膜の寿命の低下を大幅に抑制することができるので、産業上、極めて有益に利用することができる。 The solid polymer fuel cell power generation system according to the present invention can greatly suppress the decrease in the life of the solid polymer electrolyte membrane even if the power generation operation is continuously performed over a long period of time. It can be used beneficially.
