PURPOSE: A method for preparing a hydrophilic separator for a fuel cell is provided to improve hydrophilic property and electrochemical stability. CONSTITUTION: A method for preparing a hydrophilic separator for a fuel cell comprises a step of applying hydrophilic coating liquid to the surface of a separator after the manufacture of the separator for the fuel cell, and drying the separator to form a hydrophilic coating film. The method further comprises at least one of a blasting step of a flow channel of the separator, and a plasma processing step of the separator before hydrophilic coating of the separator. |
