Abstract: Disclosed are a method for manufacturing a polymer electrolyte membrane for fuel cells in which a plurality of porous reinforcement films and ionomer layers are continuously disposed or stacked, and a polymer electrolyte membrane for fuel cells manufactured thereby. The polymer electrolyte membrane for fuel cells includes the porous reinforcement films, thus having excellent mechanical stiffness and improved physical durability. Further, the polymer electrolyte membrane for fuel cells includes an ionomer layer including a catalyst for decomposing peroxide configured to block gas crossover and may thus minimize performance degradation due to gas crossover and prevent an electrical short, and the polymer electrolyte membrane for fuel cells makes it easy to adjust the position of the ionomer layer in the electrolyte membrane in the thickness direction and may thus effectively mitigate gas crossover.

Abstract: 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.

Abstract: 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.
