  • both the initial voltage and the initial current can be significantly increased, and the voltage and current are reduced after a long time. Both can be greatly reduced.
  • the positive electrode support plate 30a, the positive electrode extraction electrode 30b, the carbonized cloth 30c, the salt-containing cloth 30d, the paper sheet 30e, the metal plate 30f, and the negative electrode extraction electrode 30g are firmly bonded to each other by the cover member 30h, the negative electrode The distance between the positive electrode and the positive electrode can be kept substantially constant. Furthermore, the formation of the cover member 30h enables electrical connection between the carbonized cloth 30c and the positive electrode lead electrode 30b, and this connection can be reliably performed only by forming the cover member 30h by winding a resin tape. Therefore, the work process becomes very easy and the manufacturing cost is low.
  • the water battery In order to supply water to the water battery, it is only necessary to press the other end of the cylindrical housing in the axial direction, so that the water supply operation is simple, and the water battery is equipped with a water supply that contains liquid in advance. Can be used immediately in an emergency even in the absence of water, and can be stored for a long time and used for a long time, and an electromotive force can be obtained simply by injecting liquid. As an inexpensive battery that does not require charging, it can be widely used as an emergency power supply or emergency power supply in the event of a disaster, power outage, or other cases.

Abstract

La présente invention a trait à un appareil d'alimentation en eau de batterie hydrogène qui est équipé : d'un logement cylindrique permettant de recevoir un fluide à l'intérieur qui active une batterie hydrogène, ledit logement cylindrique étant en mesure de se contracter dans la direction axiale ; d'une première ouverture permettant d'injecter le fluide qui est logé à l'intérieur dans la batterie hydrogène, ladite première ouverture étant disposée sur une extrémité du logement cylindrique dans la direction axiale ; d'un élément de fermeture permettant de fermer la première ouverture ; et d'un élément de type tige, dont une extrémité est fixée à l'autre extrémité du logement cylindrique dans la direction axiale, et dont l'autre extrémité est conçue de manière à être en mesure d'être insérée dans l'ouverture. L'appareil d'alimentation en eau de batterie hydrogène est conçu de manière à ce que lorsque le logement cylindrique se contracte dans la direction axiale, la fermeture de l'élément de fermeture soit achevée en raison du fait que l'autre extrémité de l'élément de type tige est insérée dans la première ouverture, et que la première ouverture s'ouvre.
