description Disclosed are a fuel cell polar plate structure and a fuel cell stack, including a battery block comprising a bipolar plate, carbon papers, water-holding sheets and a proton exchange membrane; said bipolar plate has a reaction bath opened on the outer surface of each polar plate body; the front and rear sides of the reaction bath are provided with water crossing ports formed with grooves extending into the reaction bath; the fuel cell stack comprising a plurality of battery blocks, current collectors, insulating plates and end plates, wherein said battery blocks being stacked end to end to form a battery pack, and pressure-adjustable fixing mechanisms are fixed to the outer surfaces of the end plates. The independent anti-dry design improves the power generation effect and the fixing pressure regulating structure facilities controlling of the pressure between the polar plates and slows down the aging of the sealing ring.
