Description
Technical Field
The invention relates to the technical field of methanol fuel cells, in particular to a temperature-adjustable bipolar plate assembly for a methanol fuel cell.
Background
Direct methanol fuel cells, which belong to one class of Proton Exchange Membrane Fuel Cells (PEMFCs), directly use methanol aqueous solution or steam methanol as a fuel supply source without hydrogen production through reforming of methanol, gasoline, and natural gas for power generation. Compared with Proton Exchange Membrane Fuel Cells (PEMFCs), Direct Methanol Fuel Cells (DMFCs) have the characteristics of low-temperature quick start, clean and environment-friendly fuel, simple cell structure and the like. This makes Direct Methanol Fuel Cells (DMFCs) likely to become the mainstream of future portable electronic product applications.
It uses methanol directly without pre-reforming, methanol is converted at the anode into carbon dioxide, protons and electrons, as in a standard proton exchange membrane fuel cell, protons react with oxygen at the cathode through the proton exchange membrane, and electrons reach the cathode through an external circuit and do work.
Alkaline conditions: 2CH4O+3O2+4OH-＝2CO3 2-+6H2O
And (3) positive electrode: o is2+4e-+2H2O→4OH-
Negative electrode: CH (CH)4O-6e-+8OH-→CO32-+6H2O
Acid conditions: 2CH4O+3O2→2CO2+4H2O
And (3) positive electrode: o is2+4e-+4H+→2H2O
Negative electrode: CH (CH)4O-6e-+H2O→6H++CO2
During the operation of the direct methanol fuel cell, a methanol solution with a certain concentration passes through an anode flow field structure of the cell, and during the flowing process of liquid, the methanol solution passes through an anode diffusion layer and is oxidized at an anode catalytic layer. The proton as the reaction product is transferred to the cathode side through the proton exchange membrane, and the electron is transferred from the anode to the cathode through the external circuit, and does work outwards in the process. At the same time, CO is under the action of the electrolyte in the anode MEA2The gas is discharged in the form of bubbles with the methanol solution in the anode flow field. On the cathode side of the cell, air or oxygen uniformly distributed by the cathode collector plate flow field structure is diffused into the cathode catalyst layer and is electrochemically reduced by protons from the anode, and the generated water vapor or water in liquid form leaves the cathode flow field of the cell together with reaction tail gas, the expected working temperature of the cell is below 120 ℃, generally 70-80 ℃, which is slightly higher than that of the standard proton exchange membrane fuel cell, the temperature of the current methanol fuel cell is lower in a short time after methanol and air enter, which causes the cell efficiency not to be high, if the temperature is too low, the water generated by the reaction is condensed to block the gas channel, the performance of the galvanic pile is deteriorated, however, if the temperature is too high and the membrane electrode lacks water, the proton exchange membrane can not work normally or even be damaged, therefore, during operation, the temperature of the galvanic pile needs to be regulated to ensure the normal and efficient operation of the galvanic pile.
