Abstract
Roll-to-roll (R2R) manufacturing paired with slot die coating is a promising route to realize the mass production of catalyst layers of proton exchange membrane fuel cells and achieve a sharp decrease in manufacturing costs through scale effect. Catalyst ink runs through the route and governs the ultimate structure of catalyst layer. Therefore, designing and preparing an optimal high-solid content catalyst ink and figuring out how to utilize it well in the R2R process has become a significant challenge. Herein, recent progress in catalyst ink is focused on design, preparation, rheology, slot die coating, and drying process. This review is a significant step forward in providing fundamental knowledge and understanding of the nature of advanced catalyst ink and its compatibility with the R2R process which are essential for designing and manufacturing excellent catalyst layers.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
