Early research has demonstrated the benefits of ultrasonically bonding PEM fuel cell Membrane Electrode Assemblies (MEAs), in terms of durability [2] and unit cost and cycle time [3]. With these improvements in performance, the next phase in the development of the process is to move from a laboratory setup to an automated production cell capable of producing larger volumes of fuel cells while maintaining a quality ultrasonic bond. The MEAs also need to be produced more affordably and with quality standards meeting or exceeding the level set by current best manufacturing practices.
