文摘

Using baffles inside flow channels increases the value of current density. The fuel cell performance can be improved by metal foam as a flow distributor. Metal foam produces nearly uniform current density and temperature distributions. Temperature along the flow channel does not affected by the metal foam porosity. Flow Channels depth has effects on current density and temperature distributions.
