Ultrasonic Spraying for Proton Exchange Membrane Fuel Cell
In recent years, Ultrasonic spray coating technology has emerged as a relatively new technique, and it has only been applied in fuel cell applications during this period. Through extensive research and practical experiments, it has been clearly demonstrated that ultrasonic spray coating holds significant value as it represents an effective means to address the crucial issue of reducing platinum loading within fuel cells.
The determination of the optimum catalyst ink formula and the appropriate platinum loading is not a straightforward matter. These parameters are highly dependent on the specific operating conditions of the fuel cells. Different operating conditions, such as temperature, pressure, and reactant flow rates, can have a profound impact on the performance of the fuel cell and, consequently, on the ideal formulation of the catalyst ink and the optimal amount of platinum required.
When considering the cost aspect, which is of utmost importance in the commercialization and large – scale implementation of fuel cell technology, the optimum platinum loadings cannot be evaluated in isolation. Instead, they must be considered in conjunction with the cost of other core components that make up the fuel cell system.
This comprehensive and extended cost analysis approach provides a valuable perspective as it allows for a more holistic understanding of the overall cost structure. By taking into account the interplay between platinum loading costs and those of other components, it becomes possible to identify strategies that can effectively lower the cost of the entire fuel cell system.
Typically, different types of fuel cells have varying requirements for the amount of catalyst. Direct methanol fuel cells and high – temperature proton – exchange – membrane fuel cells (PEMFCs) usually demand more catalyst compared to low – temperature PEMFCs. This disparity in catalyst requirements is due to the different chemical reactions and operating environments within these fuel cell types. Given this situation, ultrasonic spray coating technology, with its unique advantages in precisely controlling the deposition of catalyst and optimizing the use of platinum, has great potential for the fabrication of direct methanol fuel cells and high – temperature PEMFCs. It can potentially enable more efficient use of catalysts in these fuel cell types, thereby contributing to improved performance and reduced costs.
