초록

A three dimensional numerical analysis was performed to study the effect of cathode inlet relative humidity on PEMFC performance characteristics. As cathode inlet relative humidity increases from 0 percent to 60 percent, the current density increases. Then, as cathode inlet relative humidity increases from 60 percent to 100 percent, the current density decreases. The two dimensional contour map analysis shows that the flooding phenomenon in cathode gas channel, gas diffusion layer, and catalyst layer leads to the decrease of current density.
