Fuel Cell Catalytic Spray Coating System in the Laboratory
Ultrasonic fuel cell catalytic spray coating system in the laboratory
The ultrasonic fuel cell catalytic spray coating system is a core experimental device independently applied in laboratory fuel cell electrode preparation research, dedicated to achieving uniform, efficient and controllable coating of catalyst layers on carbon paper substrates. Different from traditional manual coating and ordinary pneumatic spraying methods, this ultrasonic spraying equipment utilizes high-frequency ultrasonic vibration to crush catalyst slurry into fine and uniform micro-droplets, which effectively avoids the problems of large particle agglomeration, uneven coating thickness and low utilization rate of raw materials in traditional processes, providing reliable technical support for the preparation of high-performance fuel cell electrodes.
In routine laboratory experiments, the system achieves precise control of catalyst loading mass within the range of 1 to 3 milligrams per square centimeter, which is the optimal loading interval for most proton exchange membrane fuel cell electrode research. This controllable loading parameter can perfectly meet the experimental requirements of different catalyst formulations and cell performance tests, avoiding performance defects caused by excessive or insufficient catalyst loading. Excessively low loading will lead to insufficient active reaction sites, while excessive loading will cause layer accumulation, increased internal resistance and blocked gas transmission channels, and the system’s accurate regulation effectively solves these bottleneck problems.
Meanwhile, the equipment is adapted to carbon paper substrates with sizes ranging from 1×1 cm to 3×3 cm, covering the mainstream small and medium-sized electrode specification sizes for laboratory scientific research and prototype testing. The carbon paper, as a key gas diffusion layer material, has a porous and loose structure. The ultrasonic micro-droplets can uniformly infiltrate the carbon paper surface and shallow pores without causing pore blockage. The whole spraying process is carried out at room temperature and normal pressure, which will not damage the structural characteristics of carbon paper and the activity of catalyst materials. With stable operation, simple parameter adjustment and high coating repeatability, this system has become essential equipment for laboratory fuel cell catalyst modification, electrode optimization and new material performance verification experiments.
