Ultrasonic fuel‑cell catalyst coating equipment is an emerging technology for producing environmentally friendly, long‑service‑life fuel cells. Ultrasonic fuel‑cell coating technology enables catalyst materials to form a uniform coating layer on electrode surfaces, improving the utilization of active sites.
Under ultrasonic action, the formed coating improves the corrosion resistance of electrode materials, extends the service life of fuel cells, and guarantees stable electrochemical performance during long‑term operation.

As an energy‑saving, high‑efficiency and cost‑effective ultrasonic spraying technology, it has undergone extensive research and practical application in recent years. It is expected to drive further advances in hydrogen energy and fuel‑cell technologies.

 

 

 

This document specifies the technical parameters and standardized operating procedures for the ultrasonic coating process of gasoline catalysts. Optimized based on industrial practical application, the parameters are applicable to both laboratory sample preparation and large-scale production.

 

1. Ultrasonic Frequency and Power

The applicable ultrasonic frequency for this process ranges from 40 kHz to 100 kHz, with the operating power set between 10 W and 50 W. Proper configuration of ultrasonic frequency and power effectively improves the uniformity of the catalyst coating, strengthens the interfacial adhesion between the coating and the substrate, and prevents common defects such as uneven coating thickness, local peeling and surface pinholes.

 

2. Coating Material Formulation

The catalyst adopts composite materials composed of precious metals including platinum and palladium combined with carbon carriers. To eliminate powder agglomeration and achieve uniform particle dispersion, quantitative functional additives such as dispersants and binders are incorporated into the coating slurry. This stabilizes the suspension system, ensures uniform catalyst deposition during coating, and improves the forming quality and structural stability of the coating layer.

 

3. Complete Coating Procedure

First, the catalyst raw materials are formulated into coating solution or slurry with standard concentration, followed by sufficient stirring and standing to obtain a homogeneous and impurity-free suspension. The electrode substrate is then fully immersed in the prepared slurry. Under high-frequency ultrasonic vibration, catalyst particles are uniformly deposited on the substrate surface. After the coating process is completed, drying and thermal treatment are carried out sequentially to enhance the mechanical strength, wear resistance and long-term service stability of the coating.

 

4. Process Parameter Optimization

To achieve optimal coating performance, multiple groups of comparative process experiments are required to optimize core parameters, including ultrasonic power, ultrasonic treatment duration, slurry concentration and substrate immersion time. Precise adjustment of these parameters controls coating thickness, surface uniformity and interfacial adhesion, ensuring all coating properties meet design and industrial application standards.

 

5. Quality Inspection Standards

After coating fabrication, professional testing equipment including scanning electron microscopy (SEM) and X-ray diffraction (XRD) is utilized to characterize the coating microstructure, elemental distribution and catalytic activity. Comprehensive quality evaluation is performed to guarantee that the finished coating complies with production specifications and practical service requirements.
