Ultrasonic Spray Coating Machine For MEA – Cheersonic

Climate change and global warming have made greenenergy and the reduction of carbon emissions urgent andpopular topics. The Proton Exchange Membrane FuelCell (PEMFC) is a promising power source of the futurebecause of its high power density, high efficiency, lackof harmful emissions, high quality power, scalability andquick start-up.

One of the main impeding factors for fuel cell commer-cialisation is the high cost. For portable device and ve-hicular applications, fuel cells are competing with batter-ies and internal combustion engines, respectively. Thesecompetitors have been operating commercially for al-most a century with well-established infrastructure. Sincethe MEA is the most expensive component of fuel cells,reducing platinum loading of MEAs is an important re-search area for fuel cell development.

Ultrasonic spray coating technology has only been usedfor fuel cell applications in recent years. It has beendemonstrated that ultrasonic spray coating is an effectiveway to reduce platinum loading for fuel cells. The opti-mum catalyst ink formula and platinum loading are de-pendent on operating conditions. In terms of cost, opti-mum platinum loadings must be considered alongside thecost of other core components. This extended cost analy-sis is a helpful approach to lower the cost of fuel cellsystems. Normally, direct methanol fuel cells and hightemperature PEMFCs require more catalyst than lowtemperature PEMFCs. As such, ultrasonic spray coatingtechnology has great potential for the fabrication of di-rect methanol fuel cells and high temperature PEMFCs.
