Abstract

The core of a polymer electrolyte membrane fuel cell stacks are membrane electrode assemblies (MEAs). Manufacturing processes for MEA have significant impact on their performance and durability. The authors report an ultrasonic atomization and spraying technique to deposit catalyst layer directly onto the membrane to realize membrane electrode assemblies. Electrochemical test of as-fabricated MEAs indicated very good performance and reasonable stability. The Platinum yield of the fabrication process was found to be around 89%.
