The application discloses a gas diffusion module of a fuel cell, a fuel cell and a preparation method. The gas diffusion module comprises a substrate layer and a microporous layer which are arranged in sequence. The substrate layer is provided with a first hole group and a second hole group. The first hole group and the second hole group are both provided with micro-perforations. The hydrophobicity of the micro-perforations on the first surface is greater than that on the second surface. The pore diameter of the micro-perforations located in front of the air flow direction in the first hole group and the second hole group is greater than that of the micro-perforations located behind the air flow direction. Alternatively, the opening density of the micro-perforations located in front of the air flow direction in the first hole group and the second hole group is greater than that of the micro-perforations located behind the air flow direction. On any homologous line perpendicular to the air flow direction, the opening density of the micro-perforations of the first hole group is greater than that of the micro-perforations of the second hole group, and the pore diameter of the micro-perforations of the first hole group is smaller than that of the micro-perforations of the second hole group. The water in different positions of the cathode surface is kept relatively balanced, and water accumulation and excessive water loss are prevented.

The utility model provides an anti-blocking surgical drainage tube which comprises a drainage tube body, a drainage hole is formed in one end of the drainage tube body, a supporting tube is installed in the other end of the drainage tube body, a sealing cover is arranged at the other end of the drainage tube body, and a guide wire is connected to the middle of the sealing cover in a penetrating mode. A cleaning brush is arranged at the end, located in the drainage tube body, of the guide wire, the other end of the guide wire is connected with a pull ring, blockage generated at the drainage holes can be cleaned through cooperation of the guide wire and the cleaning brush, and therefore the situation that drainage of a patient is affected due to blockage of the drainage holes can be effectively reduced; the arranged supporting tube is matched with the sealing ring, so that the situation that drainage liquid enters the supporting tube when the guide wire is pulled can be effectively reduced, the situation that negative pressure is generated in the supporting tube when the baffle moves can be avoided through the arranged vent holes, and therefore the risk that the drainage liquid enters the supporting tube through the sealing ring is further reduced; and the use strength of the drainage tube body can be improved through the arranged reinforcing ribs.
