摘要： The present disclosure relates to a polymer electrolyte membrane fuel cell including a tungsten oxide-coated component, where the polymer electrolyte membrane fuel cell includes a unit cell constituted by a membrane-electrode assembly (MEA), in which an electrolyte membrane and a catalyst layer are integrally combined, a gas diffusion layer, and a bipolar plate, and tungsten oxide is coated on a surface of at least one of the membrane-electrode assembly, the gas diffusion layer, or the bipolar plate, and a method for manufacturing the same. According to the present disclosure, catalyst and cell durability can be enhanced by reducing a carbon oxidation reaction through prevention of the occurrence of high voltage under SU/SD conditions, and the performance can be maintained due to the absence of current density reduction even under SU/SD conditions.
