A first connection port 22 and a second connection port 23 are formed on the outside of the communication seat 2. The first connection port 22 and the second connection port 23 are connected to the channel 21 inside the communication seat 2 to communicate with each other. The connection port 22 corresponds to a position above the zinc-air fuel cell 3 of the first tube, and the second connection port 23 corresponds to a position above the zinc-air fuel cell 3 of the last tube (fourth tube). The first preferred feasible embodiment of the pressure difference generator 5 shown in FIG. 5D is that the pressure difference generator 5 is set as a vacuum tank 50.

One of the first connection port 22 or the second connection port 23 is installed in communication with the vacuum tank 50, and the other is directly connected to the atmospheric pressure to form a zinc-air fuel cell 3 interposed between the first tube and the first tube. The pressure difference between the zinc-air fuel cells 3 in the last tube (the fourth tube) can be set to a negative pressure difference or a positive pressure difference of the air gas drawn in or driven in.

In this way, the pressure difference formed by the vacuum tank 50 and the atmospheric pressure forces the gas in the atmospheric pressure to sequentially enter the channel 21, the communication section 210, and the first tube of the communication seat 2 from the first connection port 22 The reaction space 32 of the zinc-air fuel cell 3, the extension section 211 of the above-mentioned communication seat 2, the communication section 210, the reaction space 32 of the zinc-air fuel cell 3 of other pipes, the extension section 211 of the above-mentioned communication seat 2, the communication section 210, the most The reaction space 32 of the zinc-air fuel cell 3 of the last pipe (the fourth pipe), the extension 211 of the communication seat 2, the second connection port 23, and the vacuum tank 50.

Moreover, in the process that the gas flows along the path described above, each of the zinc-air fuel cells 3 and the communication base 2 are installed in a sealed state under the installation and assembly, and the extension section 211 of the channel 21 extends.

The two connection ports 23 are connected to the above-mentioned vacuum tank 50. In a state where the above-mentioned vacuum tank 50 has not been started and the gas has not been driven by the negative pressure to push the zinc mud electrode 40, the first tube of zinc air is in the reaction zone 320 of the battery 3 The position of the zinc slime electrode 40 is the highest, and the position of the above zinc slime electrode 40 is sequentially decreased to the position of the last tube (fourth tube) of the zinc-air fuel cell 3 in the reaction zone 320 of the zinc slime electrode 40 having the lowest height. The length of the extension section 211 of a tube of zinc air battery 3 is the longest and the position of the discharge port 203 relative to the reaction zone 320 is the lowest (the extension section 211 of the first tube of zinc air fuel cell 3 is located in the above reaction zone 320, and The extension section 211 also contains the zinc mud electrode 40).

The length of the extension section 211 is sequentially reduced to the last tube (the fourth tube). The length of the extension section 211 of the zinc-air fuel cell 3 is the shortest and the position of the discharge port 203 relative to the reaction zone 320 is the highest (because the last tube ( (Fourth tube) The extension section 211 of the zinc-air fuel cell 3 can be set to be exactly the same height as the reaction zone 320 or not in contact with the reaction zone 320, so the zinc mud electrode will not be accommodated in the extension section 211. 40).

The zinc slime electrode 40 flowing in a single direction of the air fuel cell 3 will temporarily lose the power driven by the gas, and the zinc slime electrode 40 originally flowing in the above-mentioned channel 21 will be affected by natural gravity and will face the first tube respectively. There are two different flow paths of the extended section 211 of the zinc-air fuel cell 3 and the connecting section 210 toward the other tube of the zinc-air fuel cell 3, and then they flow into the reaction spaces 32 of the different zinc-air fuel cells 3. The height position of the zinc slime electrode 40 in one tube of the zinc air fuel cell 3 will decrease, and the height position of the zinc slime electrode 40 in the other tube of zinc air fuel cell 3 will rise.

According to the foregoing description and so on, the flow mode and flow direction of the gas and the zinc mud electrode 40 will be continuously circulated in the first tube, the second tube, the third tube, and the last tube (fourth tube) zinc air. Between the fuel cells 3, if the first tube of zinc-air fuel cell 3 is connected to the vacuum tank 50 through the first connection port 22, the zinc-air fuel cell 3 of the last tube (fourth tube) passes through the above. The second connection port 23 is connected to the atmospheric pressure, and the flow direction of the gas and the zinc mud electrode 40 will be changed from the last tube (fourth tube) zinc air fuel cell 3 toward the first tube zinc air fuel cell 3.

In addition, the pressure difference generator 5 is a vacuum tank 50 (not shown) connected to the first connection port 22 and the second connection port 23 of the communication seat 2 at the same time, and can also constitute the pressure difference and complete the process.
