Ultrasonic Coating for Proton Exchange Membrane Fuel Cell

Ultrasonic Coating for Proton Exchange Membrane Fuel Cell

Climate change and global warming have become urgent topics for green energy and carbon emission reduction. Proton exchange membrane fuel cells (PEMFC) have become a promising power source in the future due to their high power density, high efficiency, no harmful emissions, high-quality power supply, scalability and fast start-up.

One of the main obstacles to the commercialization of fuel cells is the high cost. For portable equipment and vehicle applications, fuel cells compete with batteries and fuel vehicles respectively. These competitors have used sound infrastructure for nearly a century of commercial operations. Since MEA is the most expensive component in fuel cells, reducing the platinum loading of MEA is an important research area for fuel cell development.

Ultrasonic spraying is now a widely used method for catalyst synthesis, catalyst support treatment, catalyst layer fabrication, membrane electrode assembly (MEA) fabrication, and humidifier etc. for fuel cell applications. Among the abovemen-tioned uses, ultrasonic technology has been utilised mainly for MEA fabrication—especially since it has demonstratedthe capability to produce ultra-low platinum loadings.
