なっている。In order to continue such a cell reaction and to use it as a fuel cell, the electrolytic solution is circulated to remove the precipitate, and the metal electrode is continuously supplied to the container-like porous conductive material and the inside thereof. Metal-air cells composed of granular metal fuel are disclosed, for example, in PCT / FR91 / 00944. In the same publication, a metal electrode composed of a porous conductive holder having a fuel inlet opened upward and a granular metal fuel therein is present in an electrolyte space formed by opposed plate-shaped air electrodes. Disclosed is that a fuel container part having a bottom hole is provided above a battery case part of a cell, and a movable fixed amount part for supplying a fixed amount of fuel to the cell is interposed between the cell and the fuel container part. Has been done. Specifically, the movable fixed quantity unit
As shown in FIG. 10, a fixed amount plate c having a small chamber b for temporarily holding a fixed amount of fuel from the fuel container part a, and a reciprocating slide between the bottom part of the fuel container part a and the fixed amount plate c are possible. And an upper partition plate d having a hole d1 communicating between the bottom hole a1 of the fuel container portion a and the small chamber b of the fixed quantity plate c, and the fuel intake port f of the fixed quantity plate c and the cell e.

摺動する形態であり、両摺動面には、電解液や水蒸気等

動性が要求される。In the conventional fuel supply structure for a metal-air battery, the upper partition plate slides between the fuel container part and the metering plate, and the lower part between the metering plate and the battery case part. The partition plates are configured to slide, and both sliding surfaces are required to have a sealing function of preventing electrolyte and water vapor from leaking to the outside and smooth sliding properties of each partition plate.

が損なわれ、燃料供給の連続性が損なわれてしまう。However, the above-mentioned conventional fuel supply structure merely interposes the oil and fat i, and the above-mentioned sealing function and slidability are not taken into consideration. Therefore, the electrolyte and water vapor may leak to the outside, and the aluminum powder may slide on the sliding surface due to thermal expansion, electrolytic solution infiltration, electrostatic force on the sliding surface, adsorption by moisture, scratches on the sliding surface, etc. May adhere to. As a result, smooth sliding is impaired, and continuity of fuel supply is impaired.

なる。Further, in the fuel supply structure, when the upper partition plate c slides, for example, the lower edge a'of the bottom hole a1 in the fuel container portion a and the upper edge d'of the hole d1 in the upper partition plate d are formed. It is conceivable that the upper partition plate d may be locked due to the particulate metal fuel being sandwiched between the space or the upper edge b ′ of the small chamber b. This is mainly due to the fact that the particulate metal fuel adheres to the sliding surface due to dirt on the sliding surface. If the partition plate is locked in this way, the fuel will be excessively supplied, or on the contrary, it will be insufficient and stable output cannot be obtained.

The problem to be solved is to prevent the lock phenomenon and to reliably and quantitatively supply the fuel continuously to generate a stable output.

The granular metal fuel is supplied to the metal electrode of each single cell. Further, since the insulating solid lubricating film is formed on the portion forming at least one of the sliding surfaces of the movable fixed amount portion and the fuel container portion and the battery case portion, the adhesion of the granular metal fuel is surely performed. In addition to being prevented, it is possible to prevent leakage of electrolytic solution, water vapor and the like. As a result, slidability is improved, and continuity of fuel supply is achieved.

Then, when the amount of aluminum fuel in the specified metal electrode 12 decreases below a preset fuel amount, the fixed quantity plate 22 is moved back (moved in the direction A) by the drive means 6, and the small chamber 23 shown in FIG. As shown in FIG. 2 (A), the small chamber 23 is displaced from the state in which it communicates with the fuel drop hole 17 to the state in which the small chamber 23 communicates with the fuel intake port 12a via the fuel guide hole 4c, and the amount of aluminum retained in the small chamber 23 is changed. Fuel is supplied to each metal electrode 12. Such return movement of the metering plate 22 is due to the actuation command of the driving means 6 triggered by the detection of the decrease of the fuel by the conductor pieces 14a, 14b provided in the metal electrode 12.
