摘要： The present invention relates to a separator plate for a fuel cell and to a method for producing the same, and relates to an invention wherein a surface-modification layer is formed through the use of low temperature plasma processing such that it is possible to prevent the hydrophobic characteristics which occur during gasket forming and to have outstanding hydrophilic characteristics, and such that it is possible to obtain the advantageous effect of highly outstanding corrosion resistance and electrical conductivity not only initially but also even after long-term use in a fuel-cell operating environment, and also such that it is possible to maintain outstanding durability even when using a normal low-price stainless-steel sheet base material, and it is possible to reduce the unit cost of production of the separator plate for the fuel cell since surface processing can be carried out at low cost.
