▎ 摘　　要

NOVELTY - The separator comprises a graphene layer formed in a stainless steel by spraying a graphene dispersed solution in the steel to form the layer, where the graphene dispersed solution comprises graphene and an alcohol-based solvent. The graphene dispersed solution is made of conductive polymer. The graphene dispersed solution is processed with ultrasonic wave. The graphene layer has a thickness of 3-5 mu m. The dispersion of the graphene in the stainless steel having a height of 10-50 cm is carried out by applying a voltage of 10-20 kV and spraying at a rate of 50-300 mu l/minute on a substrate. USE - The separator is useful in a polymer electrolyte fuel cell (claimed). ADVANTAGE - The separator has excellent corrosion resistance and contact resistance, and can be environment-friendly, simply and economically manufactured.
