Fuel Cell MEA Coating: Key Parameters for Catalyst Layer Uniformity
Fuel cell performance and durability strongly depend on the uniformity of the catalyst layer (CL) within the membrane electrode assembly (MEA). Uneven catalyst distribution can lead to inconsistent electrochemical activity, local current density variations, hotspot formation, and accelerated degradation of fuel cell stacks. This article introduces the key parameters affecting catalyst layer uniformity, including catalyst ink properties, coating process conditions, drying control, substrate temperature, and online monitoring methods. Special attention is given to ultrasonic spray coating technology, which enables precise droplet control, low material waste, and uniform catalyst deposition for advanced MEA manufacturing. By optimizing ink formulation, coating parameters, and process control, manufacturers can achieve highly uniform catalyst layers with improved fuel cell efficiency, longer lifetime, and reduced platinum loading.
