Application of Inkjet Coating Printer to Assess MEA Cell Performance for PEFC

Abstract

This research assesses the efficiency of membrane electrode assembly (MEA) utilized for
Polymer Electrode Fuel Cell (PEFC) created by inkjet coating printer and suggests a new approach for
manufacturing catalyst layers using this printer. In general, the high viscosity catalyst slurry for the doctor
blade approach could not be directly applied to the inkjet printer. As a result, the solvent was added to this
slurry to create the catalyst ink with the proper viscosity for the inkjet coating printer. Furthermore, we
used a vacuum stirrer mill and ultrasonic wave crusher to increase the dispersibility of Pt because this
catalyst ink has a low viscosity. As a result, the inkjet printer used this new catalyst ink to build the catalyst
layer consistently. In addition,
