電気エネルギーは、そのままの形態では貯蔵が困難であるため、貯蔵可能なエ ネルギー形態に変換しなければならない。他方、安定した電力供給を行なうには 、電力需要に合わせて供給（すなわち発電）を行なう必要がある。このため、電 力会社は、常に最大需要に見合った発電設備を建設し、需要に即応して発電を行 なっている。しかしながら、図３に電力需要曲線Ａで示すように、昼間および夜 間では、電力の需要に大きな差が存在する。同様の現象は、週、月および季節間 でも生じている。 Electrical energy is difficult to store in its raw form, so it is difficult to store it in its raw form. must be converted into energy form. On the other hand, in order to provide a stable power supply, , it is necessary to supply (that is, generate electricity) in accordance with the electricity demand. For this reason, electricity Power companies always construct power generation facilities that meet maximum demand and generate power in immediate response to demand. It has become. However, as shown by electricity demand curve A in Figure 3, There are large differences in electricity demand between the two countries. Similar phenomena occur between weeks, months and seasons. But it is happening.
【０００３】 そこで、電力を効率よく貯蔵することが可能であれば、オフピーク時余剰電力 （図３のＸで示した部分に相当する）を貯蔵し、ピーク時にこれを放出すれば図 ３のＹで示した部分を賄うことができ、需要の変動に対応することができ、常に ほぼ一定の電力（図３の破線Ｚに相当する量）のみを発電すればよいことになる 。このようなロードレベリングを達成することができれば、発電設備を軽減する ことが可能となり、かつエネルギーの節約ならびに石油等の燃料節減にも大きく 寄与することができる。0003 Therefore, if it is possible to store electricity efficiently, surplus electricity during off-peak hours can be (corresponding to the part indicated by X in Figure 3) and release it at the peak time. It can cover the portion indicated by Y in 3, it can respond to fluctuations in demand, and it can always It is only necessary to generate approximately constant power (the amount corresponding to the broken line Z in Figure 3). . If such load leveling can be achieved, the power generation equipment will be reduced. This makes it possible to save energy and fuel such as oil. can contribute.
【０００４】 そこで、従来より種々の電力貯蔵法が提案されている。たとえば揚水発電が既 に実施されているが、揚水発電では設備が消費地から遠く隔たった所に設置され ており、したがって送変電損失を伴うこと、ならびに環境面での立地の制約があ ることなどの問題がある。それゆえに、揚水発電に代わる新しい電力貯蔵技術の 開発が望まれているが、その１つとしてレドックスフロー電池の開発が進められ ている。0004 Therefore, various power storage methods have been proposed in the past. For example, pumped storage power generation is already However, in pumped storage power generation, equipment is installed far away from the consumption area. Therefore, there are transmission and substation losses as well as environmental location constraints. There are other problems. Therefore, new energy storage technologies are needed to replace pumped storage power generation. The development of redox flow batteries is one example that is desired to be developed. ing.
【０００５】 図４は、既に提案されているレドックスフロー電池の一例を示す概略構成図で ある。このレドックスフロー電池１は、電池セル２、正極液貯蔵用タンク３およ び負極液貯蔵用タンク４を備え、２個のタンクを用いるため２タンク方式と呼ば れているものである。電池セル２内は、たとえばイオン交換膜からなる隔膜５に より仕切られており、一方側が正極セル２ａ、他方側が負極セル２ｂを構成する 。正極セル２ａと負極セル２ｂ内には、それぞれ、電極として正極６および負極 ７が配置されている。[0005] Figure 4 is a schematic diagram showing an example of a redox flow battery that has already been proposed. be. This redox flow battery 1 includes a battery cell 2, a positive electrode liquid storage tank 3, and It is called a two-tank system because it uses two tanks and a negative electrode liquid storage tank 4. This is what is happening. Inside the battery cell 2, there is a diaphragm 5 made of, for example, an ion exchange membrane. One side constitutes a positive electrode cell 2a and the other side constitutes a negative electrode cell 2b. . In the positive electrode cell 2a and the negative electrode cell 2b, a positive electrode 6 and a negative electrode are respectively provided as electrodes. 7 is placed.
【０００６】 図４に示したレドックスフロー電池１では、たとえば鉄イオン、クロムイオン のような原子価が変化するイオンの水溶液をタンク３，４に貯蔵し、これをポン プＰ1 、Ｐ2 で流通型電解セル２に送液し、酸化還元反応により充放電を行なう 。たとえば、正極液としてＦｅ3+／Ｆｅ2+塩酸溶液、負極電解液としてＣｒ2+／ Ｃｒ3+塩酸溶液を用いると、各酸化還元系の両極６．７における電池反応は、次 式のようになり、起電力は約１Ｖである。In the redox flow battery 1 shown in FIG. 4, an aqueous solution of ions whose valences change, such as iron ions and chromium ions, is stored in tanks 3 and 4, and distributed by pumps P 1 and P 2 . The liquid is sent to the type electrolytic cell 2, and charged and discharged by an oxidation-reduction reaction. For example, if a Fe 3+ /Fe 2+ hydrochloric acid solution is used as the positive electrode solution and a Cr 2+ /Cr 3+ hydrochloric acid solution is used as the negative electrode electrolyte, the battery reaction at both electrodes 6.7 of each redox system is as follows: The electromotive force is approximately 1V.

The reaction liquid is supplied into the battery cell 2 by pumps P 1 and P 2 as reaction liquid feeding means provided in the pipe line 13 . The supplied positive electrode electrolyte and negative electrode electrolyte react in the positive electrode cell 2a and the negative electrode cell 2b, and the reacted solutions are passed through the positive electrode electrolyte return conduit 1 and the negative electrode electrolyte return conduit 1 and 2, respectively. 14, and is returned into the positive electrode electrolyte storage tank 3 and the negative electrode electrolyte storage tank 4.
【０００９】 次に、電池セル、電解液貯蔵用タンク、電解液供給用管路および電解液戻し用 管路の接続の様子を、さらに詳細に説明する。ここで、電解液貯蔵用タンクとい うときは、正極電解液貯蔵用タンクまたは負極電解液貯蔵用タンクをいい、電解 液供給用管路というときは正極電解液供給用管路または負極電解液供給管路をい い、電解液戻し用管路というときは正極電解液液戻し用管路または負極電解液戻 し用管路をいうものとする。電解液貯蔵用タンク１０３内には、電池セル１０２ に循環供給される電解液１０４が貯蔵されている。電池セル１０２と電解液貯蔵 用タンク１０３との間には、電解液貯蔵用タンク１０３から電解液１０４を電池 セル１０２に送り込む電解液供給用管路１１１が連結されている。電池セル１０ ２で反応した電解液は、電解液戻し用管路１１２を通って電解液貯蔵用タンク１ ０３に戻される。電解液戻し用管路１１２の一端は電池セル１０２に接続され、 電解液戻し用管路１１２の他端の環流口１１２ａは、電解液貯蔵用タンク１０３ 内の電解液１０４の中に潜入している。環流口１１２ａを電解液１０４内に潜入 させているのは、ポンプ動力を低減させるためである。[0009] Next, the battery cells, electrolyte storage tanks, electrolyte supply pipes, and electrolyte return The connection of the pipes will be explained in more detail. Here, the electrolyte storage tank is called When the electrolytic When we refer to the liquid supply pipeline, we mean the positive electrode electrolyte supply pipeline or the negative electrode electrolyte supply pipeline.

In addition, the circulation port 112a of the electrolyte return conduit 112 was submerged in the electrolyte. However, Therefore, the battery cells 102 and the electrolyte return conduit 112 are always filled with electrolyte. It had been. Therefore, trouble may occur in the battery cell 102 or the electrolyte return conduit 112. If a siphon occurs or during work such as removing the battery cell 102, Due to this phenomenon, the electrolyte 104 in the electrolyte storage tank 103 is also discharged. There were problems in terms of safety and workability.
