at is the direct methanol fuel battery?
The direct methanol fuel battery belongs to one of the categories of the proton exchange membrane fuel battery .It directly use aqueous solutions of methanol as fuel and steam supply source, not through the restructuring of devices without having to re-methanol, gasoline and and then remove the hydrogen such as natural gas for power generation. Compared to proton exchange membrane fuel battery, direct methanol fuel battery low temperature of Health electricity, fuel components and battery low-risk features such as simple structure, so that direct methanol fuel battery portable electronics applications may be mainstream.
Direct methanol fuel battery
Direct methanol fuel battery is a proton exchange membrane fuel battery as a variant, it directly uses methanol , rather Needless to pre-restruct. Methanol changes into carbon dioxide, proton and electron at the anode , as the standard proton exchange membrane fuel battery, as protons through the proton exchange membrane and oxygen in the cathode reaction of electrons through the external circuit to reach the cathode, and doing work.
The expectations of the battery operating temperature is 120 ℃, which is higher than the standard proton exchange membrane fuel battery , its efficiency is about 40%. The disadvantage is that when low-temperature methanol is converted to hydrogen and carbon dioxide,when the conventional proton exchange, membrane fuel batteries need more platinum catalyst. However, this increase in costs can be due to easy access to liquid fuels and will be able to work on the revitalization Needless to dwarfs. The use of direct methanol fuel battery technology is still in its early years of development, it has successfully demonstrated and can be used as mobile phones and laptop computers power supply, the future for a specific end-user also has potential.
