The invention relates to the technical field of fuel cells, and particularly discloses a bipolar plate flow field structure and a fuel cell thereof.The bipolar plate flow field structure comprises a substrate, the substrate is provided with a fluid inlet, a flow field area and a fluid outlet which are communicated in sequence, and the flow field area is arranged on the side, used for being attached to a membrane electrode assembly, of the substrate; the flow field area is filled with a porous medium, pores are formed in the porous medium, and the pores are used for allowing working fluid flowing to the fluid outlet from the fluid inlet through the flow field area to pass through; and the porous medium is provided with a channel, the channel is connected with the direction of a connecting line between the fluid inlet and the fluid outlet, and the channel is used for guiding the working fluid to each area of the flow field area. According to the invention, the net output power of the fuel cell is improved. 本发明涉
