A material separation and transmission direct methanol fuel cell and its working method

Abstract

The invention discloses a material separation and transfer direct methanol fuel cell and a working method thereof. For the material separation and transfer direct methanol fuel cell, the anode side adopts a new type downstream transmission structure, a liquid phase pure methanol is heated and evaporated through a methanol evaporation pipeline to generate methanol vapor, the methanol vapor flows directly into that anode diffusion layer through the methanol vapor channel, a reaction product is refluxed directly to a carbon dioxide buffer isolated from the methanol vapor channel in the fuel product separation zone and discharged directly into the atmosphere, the methanol and product are transported separately, and the whole process of the fuel cell from liquid methanol flowing to carbon dioxide discharge forms a stable downstream flow path, which is conducive to the stable and efficient operation of the anode-side reaction and improved cell efficiency.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a material separation and transmission direct methanol fuel cell and a working method thereof. Background technique [0002] Direct methanol fuel cell is considered to be one of the most promising mobile power sources for electronic products due to its simple structure, normal temperature operation, high system volume specific energy, and convenient fuel storage and transportation. It has a wide range of applications in the fields of communication, transportation, and national defense. Therefore, it has become a hot research topic of many scholars at home and abroad. At present, most of the research on direct methanol fuel cells is concentrated in the field of using liquid methanol as fuel, but because most of the fuel supply of methanol fuel cells needs to be mixed with water, this reduces the energy density of the fuel, and at the same time there is serious methanol in the p...

Problems solved by technology

However, during the working process of the battery using methanol vapor as fuel, there are often problems such as uneven distribution of methanol concentration on the anode side, insufficient methanol reaction, and difficulty in discharging carbon dioxide, which greatly affect the working efficiency of the fuel cell.

[0004] Therefore, in view of the above problems of methanol fuel cells such as low efficiency, difficult distribution, and easy mixing, a methanol fuel cell with high operating efficiency and stable output is urgently needed.
