Description

Technical Field

[0001] The utility model relates to the technical field of data acquisition devices, in particular to a data acquisition device for artificial wetland microbial fuel cell experiments. Background Art

[0002] Microbial fuel cell (MFC) is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. Its basic working principle is: in the anaerobic environment of the anode chamber, organic matter is decomposed by microorganisms and releases electrons and protons. Electrons are effectively transferred between the biological components and the anode by appropriate electron transfer mediators, and are transferred to the cathode through an external circuit to form current, while protons are transferred to the cathode through a proton exchange membrane. The oxidant (usually oxygen) obtains electrons at the cathode and is reduced to combine with protons to form water.

[0003] In the prior art, a data acquisition device for a microbial fuel cell experiment needs to be installed in a wetland for data acquisition. Generally, the data acquisition device is directly fixed on a bracket, and then the bracket is inserted into the ground of the wetland for data acquisition.

[0004] However, due to the special wetland environment, which is often too humid, the data acquisition device is exposed and fixed on the bracket, which will be affected by moisture for a long time, which can easily cause the internal components of the data acquisition device to be damaged. At the same time, because there is too much rain in the wetland environment, relying solely on the data acquisition device's own waterproofness cannot guarantee its stable operation for a long time, which in turn affects the accuracy of data collection. Utility Model Content
