Among the researches of channel design, there are many researches which focused on forced convection with interdigitated channel and baffle, rather than natural convection phenonenon.
In this study, the analysis is proceeded by COMSOL, the multiphysics program, for the fluid flow, pressure and power by the FBB(Fully-Blocked Baffle) in the parallel channel. Because a bipolar plate is considered for the PEMFC unit cell, in which electrode area is 25cm², the domain size was designed for channel length which is 50mm. Because the bipolar plate will be designed for parallel channels, the numerical analysis was calculated for a shape with a single three-dimensional channel.
Through this numerical analysis, it was found a characteristic that the gas was gathered again to channel, after gas is passing through the GDL by forced convection. It was found that the fuel cell"s power was increased by the channel with baffles, more than the channel without baffle.
