【発明の詳細な説明】
本発明はヒドラジン空気又は酸素燃料電池、メ
タノール空気又は酸素燃料電池などの燃料溶解形
燃料電池に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to fuel soluble fuel cells such as hydrazine air or oxygen fuel cells and methanol air or oxygen fuel cells.
燃料溶解形燃料電池には発明者等が提案した電

ライトをポンプで循環させて電池本体に供給する
液循環形がある。 Conventionally, fuel-dissolved fuel cells are of the liquid static type proposed by the inventors, in which a mixed solution of electrolyte and fuel (hereinafter referred to as "anolyte") is kept stationary in a fuel chamber, and only fuel is supplied to the fuel chamber. There is a liquid circulation type in which the anolyte is circulated by a pump and supplied to the battery body.

するものである。 An important point of a fuel-dissolved fuel cell is how to supply fuel uniformly to each unit cell, and moreover, so that the fuel concentration is uniform over the entire surface of the electrode. Another important point is that the fuel supply quickly follows the increase in load. If the concentration of fuel is uneven in each cell or on the electrode surface, and the followability of the fuel supply is poor, not only will it be impossible to obtain a stable electrical output from the battery body, but the life of the electrode will also be shortened rapidly. This is considered to be a major obstacle to practical application. The present invention provides a liquid fuel cell that overcomes these drawbacks.
次に本発明の詳細について説明する。 Next, details of the present invention will be explained.

れる。 FIG. 1 shows a static liquid type hydrazine air fuel cell. 1 is a hydrazine electrode, 4 is an air electrode, and 5 is an electrolyte chamber. By supplying hydrazine, which is a fuel, to the fuel chamber 3 and air to the air chamber 8, electrical energy can be extracted from the electrochemical reaction between hydrazine and oxygen in the air. Air is supplied to the air chamber 8 from the air supply port 7 and exhausted from the air discharge port 9. Hydrazine has conventionally been supplied to the fuel chamber 3 from a fuel supply tube 6. Further, gas generated in the electrochemical reaction of hydrazine and oxygen is exhausted from the gas outlet 10.

があつた。 When fuel is supplied by such a fuel supply tube 6, it is difficult to obtain a stable electrical output due to retention of decomposed gas in the tube, deformation of the tube, and the like. Furthermore, a large number of fuel supply tubes 6 are required to uniformly supply the fuel to the entire surface of the electrode, resulting in a disadvantage that the structure itself becomes very complicated.

FIG. 3 is a diagram comparing output characteristics of batteries. The structure of the fuel chamber frame of the battery according to the present invention is the same as that shown in FIG. 3, while the fuel supply tubes 6 of the conventional battery are provided at four locations in the lower part of the fuel chamber 3.

よい。 Although a liquid stationary fuel cell is shown as an example of the present invention, in a liquid circulation type fuel cell, only fuel is provided in the fuel chamber frame, in addition to a flow path that circulates the anolite with a pump and supplies it to the fuel chamber. A fuel flow path for supply is provided, and the fuel chamber and the fuel flow path are fluidly connected via a porous fuel filter, so that the fuel in the fuel flow path is directly supplied to the fuel chamber. It was confirmed that it is extremely effective, similar to the liquid static type. In addition, the material of the fuel filter may be an insulator or metal, and a wide range of porosity can be used depending on the pressure conditions for pressurizing the fuel.It can be installed at the top, side, or bottom of the fuel chamber frame. Any of these is fine.
