Ultrasonic Spray Coating For Fuel Cell Applications
Ultrasonic Spray Coating For Fuel Cell Applications. Ultrasonic spray coating technology has only been used for fuel cell applications in recent years. It has been demonstrated that ultrasonic spray coating is an effective way 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 the cost of other core components. This extended cost analy-sis is a helpful approach to lower the cost of fuel cell systems. Normally, direct methanol fuel cells and high temperature PEMFCs require more catalyst than low temperature PEMFCs. As such, ultrasonic spray coating technology has great potential for the fabrication of di-rect methanol fuel cells and high temperature PEMFCs.
