Polymer Exchange Membrane Fuel Cells Coating

Polymer Exchange Membrane Fuel Cells Coating – Fuel Cell Coating – Cheersonic

Polymer exchange membrane fuel cells (PEMFC) are the devices that directly convert chemical energy into electrical energy and are potential candidates for portable and stationary power supply applications due to their several advantages over combustion engines. Among several challenges, cost and weight of PEMFC are prominent factors to be controlled for its commercialization. PEMFC bipolar plates are the components that share the major weight and cost of the overall fuel cell stack. Importantly, the PEM fuel cell needs a quite low operating temperature, which typically ranges from 70 to 85 °c, and is very safe in applications.

In a PEM fuel cell operation, the fuel is fed continuously to the anode, and the oxidant, oxygen or air, is fed continuously to the cathode. PEM fuel cells can also operate on many other fuels, which range from hydrogen to ethanol to biomass-derived materials. These fuels can either be directly fed into the fuel cell, or sent to a reformer to extract pure hydrogen, which is then directly fed to the fuel cell. The cell performance can be greatly improved using high conductive bipolarplates, high conductive current collector plates and efficient MEAs.

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 ultrasonic equipment include：
1.Highly controllable spray that produces reliable, consistent results.
2.Ultra-low flow rate capabilities, intermittent or continuous.
3.Ultrasonic vibrations continuously break up agglomerated particles and keep them evenly dispersed; maximizing platinum utilization.
4.Corrosion-resistant titanium and stainless steel construction
5.The self-cleaning function of the ultrasonic nozzle prevents clogging.
6.The platform takes up less space.
7.80% reduction in paint consumption
8.The particle diameter is optional which can more flexibly affect the through-hole property of the coating
