FUEL CELL SEPARATOR, ELECTRODE STRUCTURE FOR FUEL CELL, MANUFACTURING METHOD THEREOF, AND POLYMER ELECTROLYTE FUEL CELL COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To increase the degree of freedom in the shape of channels in a separator to enable an optimum gas channel to be designed, to enable a sufficient supply of gas below gas channel ribs, and to improve cell performance through the reduction in diffusion polarization; to improve a drainage property and to prevent flooding, thereby reducing diffusion polarization and improving cell performance; and to improve cell performance through the reduction of contact resistance.

SOLUTION: This fuel cell separator is characterized by comprising a separator substrate on which gas channel ribs are formed through vapor-phase growth of a carbon-based porous material with a nanosize structure. This application also provides an electrode structure for a fuel cell, methods of manufacturing the separator and the fuel cell, and a polymer electrolyte fuel cell comprising the electrode structure.
