Detailed Description
As shown in fig. 1 to 3, an embodiment of an aluminum fuel cell 1 according to the present invention includes a housing 101, a cavity 102 is disposed in the housing 101, an air electrode 103 and an aluminum electrode 104 are disposed in the cavity 102, a liquid inlet 105 is disposed in the center of the bottom of the housing 101 and is communicated with the cavity 102, liquid outlets 106 are disposed on two sides of the bottom of the housing 101, a vertical groove is disposed on two sides of the housing 101, the top of the vertical groove is communicated with the cavity 102, and the bottom of the vertical groove is communicated with the corresponding liquid outlet 106. As shown in fig. 2 and 3, the vertical slots are formed in two vertical rods on both sides of the housing 101, which are not shown in the drawing direction, but do not affect the understanding and implementation of the present invention by those skilled in the art. The electrolyte enters the cavity 102 from a liquid inlet 105 at the middle lower part, overflows into the vertical groove from the upper part of the vertical groove after filling the whole cavity 102, and then falls and flows out through the vertical groove and a liquid outlet 106 in sequence. Namely, in the invention, the electrolyte enters from the bottom, and overflows through the upper opening on the other side after being washed once inside the battery cell 1, and directly falls and flows out. The design of the liquid flow system ensures the liquid inlet consistency of the battery monomer 1 and simultaneously reduces the influence of series connection as much as possible.
And the liquid inlet 105 and the liquid outlet 106 are both provided with sealing rings 108, so that the sealing can be effectively realized.
Two sides of the bottom of the housing 101 are respectively provided with a fixing seat 109. The fixing seat 109 is provided with a bolt hole 110. The two ends of the single battery body 1 can be fixed by bolts, so that the installation reliability of the single battery body 1 is ensured, each single battery body 1 can be reliably installed, and the industrialization is facilitated.
A stainless steel grid 111 is arranged in the shell 101 and is positioned outside the electrolytic membrane corresponding to the air electrode 103. Because the electrolyte has pressure in the battery monomer 1, so increase stainless steel grid 111 in the outside of electrolytic film, stainless steel's grid 111 can guarantee the intensity of grid 111 well, does not let the electrolytic film atress extrude outward. By adopting the stainless steel grid 111, the thickness of the battery cell 1 is effectively reduced under the condition of ensuring the strength, and the power density of the battery is increased under the condition of the same space size.
The bottom of the shell 101 is provided with a fixing groove 112 for fixing an aluminum block corresponding to the aluminum electrode 104. The fixing groove 112 can ensure the fixation of the aluminum block in the installation and reaction processes, so that the alignment accuracy of the inserted aluminum block can be improved, and the industrialization is facilitated.
The shell 101 is provided with an exhaust port 107 communicated with the cavity 102. The exhaust port 107 is used to exhaust gas during the reaction of the battery cell 1.
And a waterproof vent valve 113 is arranged at the exhaust port 107. The exhaust port 107 is provided with a waterproof vent valve 113, so that effective sealing can be realized while exhaust is ensured.
