description Belonging to the technical field of fuel cells, the invention relates to a fuel cell variable density dotted staggered water drop flow field device, which comprises a fuel cell flow field plate, the two ends of the fuel cell flow field plate are respectively provided with a reactant inlet and a reactant outlet, and in the fuel cell flow field plate, the reactant inlet is communicated with the reactant outlet. A plurality of water-drop-shaped baffles are arranged along the reactant inlet and the reactant outlet in a staggered manner, and the distribution density of the water-drop-shaped baffles is gradually reduced along the flowing direction of the reactant. According to the invention, the distribution characteristic of water vapor in the flow field of the fuel cell along the flow direction is fully considered, the uniform distribution of reactants can be efficiently realized, the water management and mass transfer performance is better, the two-phase flow resistance can be greatly reduced by low-flow-resista
