Fuel cell comprising single layer bipolar plates, water damming layers and MEA of diffusion layers locally treated with water transferring materials, and integrating functions of gas humidification, membrane hydration, water removal and cell cooling
A fuel cell comprising single layer bipolar plates, water damming layers(WDL) and membrane electrode assembly (MEA) with gas diffusion layers(GDL) locally treated with water transferring materials, and integrating functions of gas humidification, membrane hydration, water removal and cell cooling is disclosed. This fuel cell is constructed with proton exchange membrane (PEM) and catalyst layers on both sides of PEM, with GDL, on top of catalyst layers, locally impregnated with water transferring materials, and single layer bipolar plates installed on both sides of GDL as cathode and anode. On one side of the plates, as anode, flow channels are structured for hydrogen rich reactant flow, capable of accommodating cooling water, and on the other side, as cathode, flow channels are structured for oxidant flow, capable of accommodating cooling water, with WDL treated with water transferring materials, placed between flow channels of cooling water flow and gas diffusion layers and in direct contact with said water on one side and said layers on the other.
