catalyst slurry preparation using a hydrodynamic

Abstract. In this study, we used a hydrodynamic cavitation method to disperse catalyst slurries for polymer electrolyte fuel cells (PEFCs) for the first time. Continuous flow processing using this method enables the mass production of a membrane–electrode assembly (MEA) for PEFCs. Here, a hydrodynamic cavitation method was compared with a batch-type ball-milling method that …
