摘要： The present invention provides a fuel cell stack with enhanced freeze-thaw durability. In particular, the fuel cell stack includes a gas diffusion layer between a membrane-electrode assembly and a bipolar plate. The gas diffusion layer has a structure that reduces contact resistance in a fuel cell and is cut at a certain angle such that the machine direction (high stiffness direction) of GDL roll is not in parallel with the major flow field direction of the bipolar plate, resulting in an increased GDL stiffness in a width direction perpendicular to a major flow field direction of a bipolar plate.

摘要： Disclosed is a fuel cell with enhanced mass transfer characteristics in which a highly hydrophobic porous medium, which is prepared by forming a micro-nano dual structure in which nanometer-scale protrusions with a high aspect ratio are formed on the surface of a porous medium with a micrometer-scale roughness by plasma etching and then by depositing a hydrophobic thin film thereon, is used as a gas diffusion layer, thereby increasing hydrophobicity due to the micro-nano dual structure and the hydrophobic thin film. When this highly hydrophobic porous medium is used as a gas diffusion layer for a fuel cell, it is possible to reduce water flooding by efficiently discharging water produced by an electrochemical reaction of the fuel cell and to improve the performance of the fuel cell by facilitating the supply of reactant gases such as hydrogen and air (oxygen) to a membrane-electrode assembly (MEA).

摘要： The present invention provides a porous medium with increased hydrophobicity and a method of manufacturing the same, in which a micro-nano dual structure is provided by forming nanoprotrusions with a high aspect ratio by performing plasma etching on the surface of a porous medium with a micrometer-scale surface roughness and a hydrophobic thin film is deposited on the surface of the micro-nano dual structure, thus significantly increasing hydrophobicity. When this highly hydrophobic porous medium is used as a gas diffusion layer of a fuel cell, it is possible to efficiently discharge water produced during electrochemical reaction of the fuel cell, thus preventing flooding in the fuel cell. Moreover, it is possible to sufficiently supply reactant gases such as hydrogen and air (oxygen) to a membrane electrode assembly (MEA), thus improving the performance of the fuel cell.
