ABSTRACT:
A design of bipolar plate gas moisturizing apparatus of the fuel cell is disclosed. Using a channel installed in the middle section of fuel channel and a water-absorptive material attached to its bottom, water is directly guided into the fuel channel of the bipolar plate in the fuel cell. The fuel inside the fuel channel thus obtains sufficient water to enhance the humidity of the proton exchange membrane and the efficiency of the fuel cell.
