FUEL CELL POLAR PLATE STRUCTURE AND CELL STACK

The present invention relates to the technical field of electrochemistry, and in particular to a fuel cell polar plate structure and a cell stack. The fuel cell polar plate structure comprises a cell block; the cell block is composed of a bipolar plate, carbon papers, water soaking sheets, and a proton exchange membrane; the bipolar plate comprises a plate body, the outer surface of the plate body is provided with a reaction groove, the front and rear sides of the reaction groove are provided with water passing ports, the water passing ports penetrate through the outer surface of the plate body, and grooves are formed in the surfaces of the water passing ports and extend into the reaction groove. The cell stack comprises a plurality of cell blocks, current collector plates, insulating plates and end plates. The cell blocks are stacked end to end to form a battery pack; the insulating plates are attached to the side surfaces of the current collector plates, the end plates are attached to the side surfaces of t
