The invention relates to the technical field of fuel cells, and specifically to a negative electrode flow field plate bionic structure capable of improving the drainage performance of a fuel cell. The bionic structure comprises an upper supporting layer, an outer gasket, a negative electrode flow field plate, an inner gasket, a lower supporting layer, a liquid-absorbing material, a negative electrode gas diffusion layer, a gasket and a negative electrode catalyst layer, wherein the outer gasket is arranged between the upper supporting layer and the negative electrode flow field plate; the inner gasket is arranged between the negative electrode flow field plate and the liquid-absorbing material; the negative electrode gas diffusion layer is arranged between the liquid-absorbing material and the negative electrode catalyst layer; and the gasket is arranged between the negative electrode flow field plate and the negative electrode catalyst layer. By adoption of the structure, the design of the bionic structure can better satisfy the bioengineering principle, so that the drainage speed of the fuel cell can be improved to a large extent; the bionic structure can be widely applied to fuel cells of multiple specifications; and a water-logging phenomenon in the fuel cell can be effectively prevented.
