Ultrasonic Bonding of Membrane-Electrode-Assemblies of Fuel Cells

Abstract

Ultrasonic bonding has a great potential for manufacturing of membrane electrode assemblies (MEAs) of fuel cells (FCs) due to its short process cycle time and low energy consumption.  Before introduction of the bonding process into the industry, a detailed and elaborate investigation of the effects of the processing parameters on the bonding quality is necessary.  We develop a finite element model of the ultrasonic bonding for MEAs of FCs.  The model can be used as a computational framework for initial evaluation of the effectiveness of ultrasonic boding for MEAs of FCs.
