Transport Phenomena in Micro and MEMs Fuel Cells

As fuel cell size decreases, the transport phenomena of the fuels and water changes in the fuel cell. In standard fuel cell designs, the movement of fuel and water is governed by volumetric effects, but surface effects become critical as dimensions shrink. A good rule of thumb is that millimeter-scale devices are small enough for...

Considerations for Micro and MEMs Fuel Cells

The design elements of a micro or MEMs fuel cell stack are the same as a larger fuel cell stack, except that there should be special considerations for...
