The electrode end 2 of the ribbed electrode 1 is filled with a filler 3. The voids of the filler 3 are filled with phosphoric acid. As the filler 3, fine powder having heat resistance and phosphoric acid resistance such as carbon, graphite and SiC is usually used. The filling capacity is 30 to 55%, preferably 40 to 50% of the voids at the electrode ends.

のである。Here, the reason why the filling capacity of the filling material 3 is set to 30 to 55%, preferably 40 to 50% of the void at the end of the electrode will be described. As a result of diligent research by the present inventors, it has been clarified that the filling capacity of the filling material with respect to the voids at the end portions of the ribbed electrode has a critical point.

That is, a ribbed electrode having a porosity of about 70% was used, and the voids at the ends of the electrode were filled with the filler amount appropriately changed so that the filling capacity was 20 to 60%. As the filler, carbon having a particle diameter of 2 microns or less was used. Then, after the solution in which this carbon was dispersed using water and a small amount of a dispersant was impregnated into the ribbed electrode end and dried, the average pore diameter was measured, and phosphoric acid was further impregnated to check the foaming pressure. It was

It was revealed that the average pore diameter was not significantly reduced even when the content was more than 100%.

分がリークの原因となるため、気孔径の分布はできるだ
け均一であることが望ましい。従って、図３（Ａ）に示
した程度の充填容量では不十分であると考えられる。Although the exact cause of this phenomenon is unknown, it is presumed as follows. That is, FIG. 3 shows a state in which one pore existing at the end of the electrode is filled with the filling material. However, when the filling material is small, as shown in FIG. Since the filler is filled around the pores, it is considered that the decrease in pore diameter is small. Then, it is considered that the distribution of the pore diameter becomes relatively non-uniform because there are a portion having a small pore diameter filled and a portion having a large pore diameter not filled. However, in the gas seal, a portion having a large pore diameter causes a leak, and therefore it is desirable that the distribution of the pore diameter be as uniform as possible. Therefore, it is considered that the filling capacity shown in FIG. 3 (A) is insufficient.
【００１３】また、図３（Ｂ）に示した様に、充填材の
充填容量の増加に伴い気孔径も徐々に減少するが、ま

えられる。このことから電極端部の空隙に対する充填材
の充填容量は、気孔径が減少し始める３０％程度以上必
要であり、好ましくは気孔径が減少している４５％以上
であるといえる。Further, as shown in FIG. 3 (B), the pore diameter gradually decreases as the filling capacity of the filler increases, but it can be said that the decrease in pore diameter is still small. When the filling material is further increased to reach a certain capacity or more, as shown in FIG. 3 (C), the pores become innumerable small holes or innumerable small cracks, and the pore diameter rapidly increases. It is considered that the pore size decreases to a relatively uniform value and the pore size distribution becomes relatively uniform. From this, it can be said that the filling capacity of the filling material with respect to the voids at the end of the electrode needs to be about 30% or more at which the pore diameter starts to decrease, and preferably 45% or more at which the pore diameter decreases.

と、小さい気孔部分に含浸することができず、この部分
からガスがリークすることが判明した。On the other hand, if it is 55% or more, the pore diameter is further reduced, but it becomes difficult to uniformly fill the entire electrode end portion. This is because in order to increase the volume of the filler to 55% or more, it is necessary to increase the concentration of the filler in the solution to be impregnated. As a result, the viscosity of the solution containing the filler is increased and the rib This is because it will be greatly affected by the pore diameter of the attached electrode. That is, as shown in FIG. 4, as a result of examining the relationship between the filler concentration and the viscosity of the filler-containing solution, it was revealed that the viscosity exponentially increases with the increase of the filler concentration. On the other hand, the pore diameter of the ribbed electrode generally varies, and there are locally small pore diameter portions. Therefore, it has been found that when the viscosity of the solution is high as described above, the small pores cannot be impregnated, and gas leaks from this portion.
【００１５】このように、リブ付電極端部の空隙に対す
る充填材の充填容量にクリティカルな点があることが明
らかになった。As described above, it has been revealed that there is a critical point in the filling capacity of the filling material with respect to the voids at the end portions of the ribbed electrodes.
【００１６】次に、充填材の充填容量と泡出圧力の関係

加する。このことは、気孔径の減少に従ってシール性は
徐々に増加し、充填材の充填容量が４０％以上となると
シール性は急激に増加することを示している。Next, the relationship between the filling capacity of the filling material and the foaming pressure will be described. That is, as shown in FIG. 5, the bubble generation pressure rises from the filling capacity of the filling material of about 30% of the voids at the electrode end and gradually increases. And the filling capacity is 40%
When it becomes above, the foaming pressure rapidly increases. This trend is
This corresponds to the change in the pore diameter shown in FIG. That is, the bubble generation pressure gradually increases as the pore size decreases, and the bubble generation pressure also rapidly increases at a filling volume of 40% or more where the pore size sharply decreases. This indicates that the sealability gradually increases as the pore diameter decreases, and the sealability sharply increases when the filling capacity of the filler becomes 40% or more.

い。From the above results, the filling capacity of the filling material with respect to the voids at the electrode ends is 30 to 55%, preferably 40 to 5%.
By setting the appropriate capacity to 0%, it is possible to obtain an electrode end portion having a small pore diameter and a relatively uniform pore distribution, and it is possible to greatly improve the gas sealing property. Although carbon is used as the filler in the above-mentioned examples, it goes without saying that the same effect can be obtained with other heat-resistant and phosphoric acid-resistant powders of graphite, SiC, Teflon, or the like.

Further, the filling capacity of the filling material with respect to the voids at the electrode end portion was 45%. A battery was constructed using the ribbed electrode having this gas sealing structure, and the battery was operated for a long time, and the potential change and the gas mixture amount were investigated. The gap at the end of the ribbed electrode before the test was approximately 1
It was confirmed that the phosphoric acid was filled with 00%.

The characteristic curve X 1 according to the present embodiment is different from the characteristic curve Y 1 according to the conventional example even after a long time operation. It was revealed that the change was small and the battery performance did not deteriorate. Regarding the mixing amount of the reaction gas, the temporal change of the CO 2 concentration on the cathode side was examined. As a result, as shown in FIG. 7, it is shown that the characteristic curve X 2 according to the present embodiment has a lower concentration than the characteristic curve Y 2 of the conventional example even after a long time operation. It was This indicates that the reaction gas did not leak from the electrode end portion.

Preferred are carbon, graphite, SiC, and Teflon.
Further, it is desirable that the particle diameter of the powder is small, and it is preferable that the particle diameter is at least several microns or less. Furthermore, it is also possible to mix and use several kinds of powders having different particle sizes. Further, it is preferable that the shape of the particles is as close to a spherical shape as possible. This is because if the particles have the same particle size, the closer they are spherical, the smaller the viscosity of the solution, the better the fluidity, and the more uniform the filling.

せきして充填する方法が望ましい。Next, any method may be used to fill the end portions of the ribbed electrodes with the filling material, but the wet filling method can provide the most uniform filling. That is, it is desirable to pressurize a solution in which the filler is dispersed in a solvent to fill the end portion of the ribbed electrode, or to immerse the electrode end in a solution in which the filler is dispersed in the solvent to fill the electrode.

部の内部に気泡が残る場合があるからである。As a drying method for removing the solvent after filling, it is desirable to uniformly and gradually raise the temperature of the entire ribbed electrode to dry it, and the drying temperature is not lower than the boiling point of the solvent. The reason for this is that if drying is performed from only one direction, the filler will be biased toward the heating surface side as the solvent evaporates and become non-uniform. Further, if the material is rapidly dried, the filler-containing solution may be bumped to scatter the filler, and bubbles may remain inside the electrode ends.
