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: 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).

Abstract: A failure diagnosis apparatus that includes an alternating current (AC) absorption unit that is connected to the fuel cell stack and switched based on an applied AC signal to enable a current from the fuel cell stack to flow. In addition, an AC signal generator is configured to generate the AC signal and supply the generated AC signal to the AC absorption unit. As the current from the fuel cell stack is absorbed by the AC absorption unit based on an alternating signal, a stack current input into a diagnosis processing unit includes an AC component, thus the diagnosis processing unit may diagnose fuel cell stack failure by analyzing a frequency of the AC component.
