MEA spraying technology

A membrane electrode assembly (MEA) is a stack of components for proton exchange membranes (Pems) or basic anion exchange membranes (AAEM), catalysts, and plate electrodes for fuel cells and electrolyzers.

In recent years, ultrasonic spraying technology has only been applied to fuel cells. Ultrasonic spraying is an effective method to reduce PT load of fuel cells. The optimum catalyst ink formulation and platinum loading depends on operating conditions. In terms of cost, the optimal platinum load must be combined with the cost of other core components. This extended cost analysis is an effective way to reduce the cost of fuel cell systems. In general, direct methanol fuel cells and high temperature PEMFCs require more catalysts than low temperature PEMFCs. Therefore, ultrasonic spraying technology has great potential in manufacturing direct methanol fuel cells and high temperature PEMFC.
