    摘要： The present invention provides a gasket for reducing stress concentration in a fuel cell stack, which prevents damage or deformation of a separator and further prevents a position shift of the gasket by reducing stress concentration formed at a specific region by deformation of the gasket due to a compression force.Accordingly, the present invention provides a gasket including a T-shaped or cross-shaped gasket joint to form hydrogen, air and coolant manifolds, and the gasket joint has a structure in which two joint branches forming an angle of 180° in the opposite direction to each other are joined at one point with a particular angles so as to reduce stress concentration formed due to compression force by deformation of the gasket.

    摘要： The present invention provides a fuel cell separator and a method for surface treatment of the same, in which ionized nanoparticles are attached to the surface of a separator to form fine projections such that the surface of the separator exhibits superhydrophobicity. For this purpose, the present invention provides a method for surface treatment of a fuel cell separator which provides nanoparticles for forming fine projections on the surface of the separator to a discharge electrode and ionizes the nanoparticles by an arc discharge generated in the discharge electrode. The ionized nanoparticles are then attached to the surface of the separator by an electric field generated by applying a high voltage between the separator and the discharge electrode, thereby forming fine projections for imparting superhydrophobicity.
