Abstract

The invention discloses an anolyte flow homogeneous catalysis fuel cell and a preparation method thereof. The fuel cell comprises a bipolar plate structure, and the bipolar plate structure comprises an anode plate, a cathode plate, and a membrane electrode located between the anode plate and the cathode plate. The membrane electrode comprises an anode, a proton exchange membrane, a catalyst layerand a cathode, which are sequentially arranged in a stacked mode in the direction from the anode plate to the cathode plate. The anode is made of hydrophilic materials, and the cathode is made of hydrophobic carbon paper. The fuel cell is provided with a fuel reaction chamber for containing anolyte at one side of the anode plate with the double-folded-plate structure, and the anolyte comprises fuel, acid and a catalyst, wherein the fuel is a biomass material. A homogeneous catalysis mode is adopted, so the anti-pollution and anti-poisoning capacity is high, the use amount of a membrane electrode noble metal catalyst is small, and the cost is saved.

Description

technical field

[0001] The invention relates to the field of batteries, in particular to an anode liquid flow homogeneous catalytic fuel cell and a preparation method thereof. Background technique

[0002] A fuel cell is a device that converts chemical energy stored in fuel and oxidant directly into electrical energy. Compared with other fuel cells, the exchange membrane fuel cell has the characteristics of lower operating temperature, faster start-up, high energy conversion efficiency, simple structure, wide fuel source, and zero pollution of emissions. It can be used in vehicle power supplies and portable power supplies. , communication base station backup / emergency power supply, etc. Currently the most in-depth research is hydrogen fuel cells, such as figure 1 As shown, hydrogen reaches the anode through the gas flow field on the anode side, passes through the gas diffusion layer to the anode catalyst layer, and undergoes an adsorption-desorption reaction with the catal...
