This extended cost analysis 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 ...

These system components typically have a trigger or button to initiate the spray when they are ... does not propel the liquid coating, and the applicator is typically fed by gravity or a low pressure ...

Using electron microscopy, it was observed that gravure coating produced catalyst layers with larger pores than catalyst layers produced by ultrasonic spray coating. In situ performance testing of the ...
