Ultrasonic Coating of Platinum Nanocatalysts

Ultrasonic Coating of Platinum Nanocatalysts – Cheersonic

The study of proton exchange membrane fuel cells (PEMFCs) has received intense attention due to their wide and diverse applications in chemical sensors, electrochemical devices, batteries, supercapacitors, and power generation, which has led to the design of membrane-electrode assemblies (MEAs) that operate in different fuel cell types. Commonly, platinum nanocatalysts and their alloys present high catalytic activities, stability, durability, and selectivity for the cathodic reaction in these energy conversion devices. The proton produced as hydrogen oxidized at the anodic side is transported through the membrane toward the cathode in the form of species H+·nH2O, reacting in a multi-electron charge transfer process to water formation.

Ultrasonic Coating of Platinum Nanocatalysts - Cheersonic

Cheersonic’s fuel cell catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings. Using the company’s patented ultrasonic spray head technology, it can spray uniformly and efficiently on proton exchange membranes and gas diffusion layers. Uniform catalyst coatings are deposited onto PEM fuel cells, GDLs, electrodes, various electrolyte membranes, and solid oxide fuel cells with suspensions containing carbon black inks, PTFE binder, ceramic slurries, platinum and other precious metals.

The advantages of Cheersonic’s fuel cell catalyst coating systems include:

1.Capable of coating PEMs with very small liquid sample sizes (only 10ml of catalyst solution necessary to coat multiple PEMs). Ideal for R&D phase.
2.Ultra-low flow rate capabilities
3.The spray beam is highly controllable for reliable and consistent results.
4.Significantly reduced machine downtime for maintenance
5.Spraying proton exchange membrane with high uniformity and good adhesion
6.Heating plate, vacuum plate or combination of heating plate and vacuum plate
7.Non-clogging atomized spray that does not deviate.
