Development of Direct Methanol Fuel Cells
Development of Direct Methanol Fuel Cells – Fuel Cell Catalyst Coating – Cheersonic
The direct methanol fuel cell (DMFC), which directly converts the chemical energy of methanol into electrical energy, is one of the most promising alternative power sources for transportation, potable electronics and stationary applications. Although the DMFC has a lower power density than the hydrogen fuel cell, the high theoretical energy storage capacity of methanol has the potential to increase the energy density of the DMFC system above that of competing electrochemical power sources. The ease of use of a liquid fuel, which is more convenient to store and refuel, makes the DMFC an attractive alternative to batteries and combustion engines. Solid polymer electrolytes (SPE), mainly proton conducting polymer membranes, have been used in DMFCs.
Cheersonic’s ultrasonic equipment is suitable for spraying catalyst solutions containing carbon black ink suspension, platinum slurry and other precious metal solutions. From R&D to production, our non-clogging technology results in greater control of coating attributes, significant reduction in materials usage, and reduced maintenance and downtime. It can prepare fuel cell proton exchange membrane with excellent performance. It integrates multiple systems such as ultrasonic, dispersion, carrier gas, liquid, heating station, vacuum adsorption, and exhaust emission control.
The advantages of Cheersonic’s fuel cell catalyst coating systems include the following：
1.Very high Platinum utilization proven in MEA fabrication; as high as 90%.
2.Non-clogging
3.Low-flow spray reduces spillage and air pollution.
4.Continuous or intermittent operation possible
5.Highly porous coatings are extremely durable, preventing cracking or peeling of catalyst layer.
6.No moving parts to wear out.
7.Minimal maintenance and downtime.
8.Robust design and materials resist corrosion.
9.Ultrasonic energy disperses the agglomerated particles, producing a homogeneous coating.
