Spray Coating Nafion Membrane
Ultrasonic Spray Coating Nafion Membrane. Ultrasonic spraying technology for high-performance proton exchange membrane fuel cell electrode manufacturing.
The manufacturing technology of the membrane electrode assembly (MEA) significantly affects the performance and durability of the proton exchange membrane (PEM) fuel cell. In our company’s research, ultrasonic spraying technology has been used to manufacture gas diffusion electrodes of different sizes, up to 1000 cm2. Catalyst ink consisted of 70 wt% catalyst and 30 wt% Nafion in a 1:7 water to 2-propanol solution. The platinum loading of the electrode was adjusted to 0.4 mg Pt/cm2.
A uniform film was obtained using ultrasonic coating method. Multilayer formation preserves the porosity of the electrode, prevents flooding of the electrode surface during coating, and enhances reactant transport during fuel cell operation. Therefore, high-performance, repeatable, and large-area electrodes can be fabricated through ultrasonic spraying technology.
