description Disclosed are a porous transport layer and a preparation method therefor. The preparation method includes the following steps: S1, machining side-by-side elongated recesses on one side surface of a metal sheet; S2, cutting the metal sheet provided with the elongated recesses into a desired shape; S3, stacking a plurality of cut metal sheets such that adjacent metal sheets are tightly attached and firmly connected to form a metal block having regular pore structures inside; and S4, cutting the metal block along a cross section of the metal block, where the cutting thickness matches the thickness of the desired porous transport layer, and a cut sheet structure with micropores being regularly distributed on the surface is used as the porous transport layer. The present invention can solve the problems that titanium fiber felts in the prior art have poor diversion performance, low contact efficiency and large contact surface resistance.
