の燃料供給方法を提供するものである。This method is compared to the method of supplying fuel to the fuel chamber using a fuel supply tube, which is a liquid stationary type that keeps a mixed solution of electrolyte and fuel (hereinafter referred to as "anolite") stationary in the fuel chamber. A remarkable effect was observed in terms of uniform supply of the battery body to each unit cell. Similar effects were also observed in the liquid circulation type, in which the anolyte was circulated by a pump, and the load followability of the fuel supply was also improved. However, if the shape of the fuel filter is the rectangular shape proposed earlier, the decomposed gas of the fuel will be supplied to the bottom of the fuel filter, and if the battery is operated for a long time, the fuel will not be supplied to each unit cell. The present invention provides a method for supplying fuel to a liquid fuel cell using a fuel filter, which solves these drawbacks.

一実施例である。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 9 and is discharged from the air discharge port. Hydrazine is supplied to the fuel chamber 3 through a fuel filter 6 through a fuel flow path. In addition, ``The gas generated in the electrochemical reaction of hydrazine and oxygen is exhausted from the gas outlet electric arm.Figure 2 shows the fuel chamber frame 2.
FIG. A cutout inside the fuel chamber frame 2 is the fuel chamber 8, which has a gas exhaust row at the top, an air exhaust outlet 18 at the top right, and an air supply port at the bottom left.
A porous fuel filter is provided at the bottom of the fuel channel hole and is adhesively held in the frame to fluidically connect the fuel chamber 3 and the fuel channel. In the evening, as shown in Figure 3, the fuel decomposition gas 2 stagnates on the surface of the fuel filter and becomes a hindrance to the fuel supply. This is an embodiment of a fuel filter according to the present invention in which a protrusion is immersed into fuel.

Even if the fuel decomposition gas stagnates on a part of the surface, the fuel can be uniformly supplied as shown by the arrow through the portion of the protrusion where it does not stagnate.
