Low Platinum Loading Fuel Cell Developed by Ultrasonic Spraying
Research on low-platinum-loaded high-temperature proton exchange membrane fuel cells developed by ultrasonic spraying technology. The following is some key information and summary:
I. Research background and significance
Proton exchange membrane fuel cell (PEMFC) is an efficient and environmentally friendly energy conversion device, widely used in new energy vehicles, distributed power generation and other fields. However, as a key catalyst material for PEMFC, its high price limits the large-scale commercial application of PEMFC. Therefore, the development of low-platinum-loaded PEMFC is of great significance.
II. Research content and methods
This study achieved the low-platinum-loaded preparation of high-temperature proton exchange membrane fuel cells (HT-PEMFC) through ultrasonic spraying technology. Ultrasonic spraying technology uses ultrasonic vibration to atomize the platinum catalyst solution into tiny droplets and evenly spray them on the electrode surface to form a catalyst layer with low platinum loading.
III. Research results
Platinum loading optimization: Different platinum loadings (from 0.138 to 1.208 mg/cm²) were tested in the study, and the optimal platinum loading was found to be 0.350 mg/cm². The fuel cell performance at this loading is the best.
Performance improvement: Low platinum loading GDEs (gas diffusion electrodes) show excellent performance in HT-PEMFC, with cathode mass power up to 0.967 W/mg Pt.
Coating quality: Ultrasonic spraying technology has the advantages of high coating uniformity, high raw material utilization, and high coating thickness control accuracy, which helps to improve the performance and stability of fuel cells.
IV. Technical advantages and application prospects
Cost advantage: Low platinum loading PEMFC significantly reduces the cost of catalyst materials, which helps to promote the commercialization of PEMFC.
Performance improvement: By optimizing the platinum loading and catalyst layer structure, low platinum loading PEMFC reduces costs while maintaining high performance.
Application prospects: This technology can be widely used in new energy vehicles, distributed power generation and other fields, providing strong support for the use of clean energy.
V. Conclusion
The low platinum loading high temperature proton exchange membrane fuel cell developed by ultrasonic spraying technology maintains high performance while reducing catalyst costs. This study provides strong support for the commercial application of PEMFC and demonstrates the great potential of ultrasonic spraying technology in the field of fuel cell preparation.
VI. Future research directions
Further optimize platinum loading: explore the performance of fuel cells at lower platinum loading to further reduce costs.
Improve catalyst activity: develop new catalyst materials or modify existing catalysts to improve their activity and stability.
Improve preparation process: optimize the process parameters and operation procedures of ultrasonic spraying technology to improve preparation efficiency and product quality.
The above information is summarized and analyzed based on publicly published research results and the characteristics of ultrasonic spraying technology. With the continuous deepening of research and the continuous development of technology, the performance and application prospects of low platinum loading high temperature proton exchange membrane fuel cells will be further improved.
