AI Technical Summary
Technical Problem
In existing microbial fuel cells, replacing the proton exchange membrane is inconvenient, requires cumbersome tools, and affects battery performance.
Method used
The internal cavity of the shell is divided into two flow channels by a partition mechanism. Each flow channel is equipped with a proton exchange membrane. The proton exchange membrane can be replaced individually by a rotating shaft and a locking mechanism. Replacement is performed by closing the flow channel through a switching plate, which simplifies the operation.
Benefits of technology
It improves the ease of replacement and stability of proton exchange membranes, reduces the probability of contamination between flow channels, and increases proton throughput efficiency.

Abstract
This utility model relates to the field of microbial fuel cell technology, specifically a microbial fuel cell device, including a shell. A cover plate is fixedly connected to the top of the shell, and a partition mechanism is rotatably connected to the bottom of the cover plate. This utility model divides the inner cavity of the shell into two flow channels through the partition plate of the partition mechanism. Each flow channel is equipped with a proton exchange membrane. When the microbial fuel cell is working normally, the two flow channels are connected simultaneously, thereby increasing the working area of the proton exchange membrane and thus increasing the working efficiency. When the proton exchange membrane needs to be replaced, a switching plate is used to close one flow channel, and the proton exchange membrane in that flow channel can be removed from the slot for replacement. At the same time, the probability of cross-contamination between the two ends of the flow channel is reduced. The cutting plate is rotated again to close the other flow channel and replace the other proton exchange membrane. This solves the problem that the bolt-fastened installation method of the proton exchange membrane is not convenient for replacement.
