Abstract: The present invention provides a microtextured proton exchange membrane for a fuel cell and a processing method thereof. A plurality of concave-convex composite textures are distributed in a gradient pattern of being dense inside and sparse outside on a cathode surface of the proton exchange membrane for the fuel cell. The plurality of concave-convex composite textures are petal-shaped and each include a pit and a protrusion. The protrusion is arranged along an edge of the pit, and a plurality of hemi-ellipsoidal micro-pits are uniformly distributed on an inner surface of the pit. The cathode surface is divided into a central region, an intermediate region, and a peripheral region according to distances between the adjacent concave-convex composite textures, and in each of the regions, the distances between the adjacent concave-convex composite textures are gradually increased from inside to outside in a gradient pattern.
