Abstract
The degree of freedom in the shape of channels in a separator is increased, enabling an optimum gas channel to be designed, enabling a sufficient supply of gas below gas channel ribs, and improving cell performance through the reduction in diffusion polarization. Drainage property is also improved and flooding is prevented, thereby reducing diffusion polarization and improving cell performance. Cell performance is also improved through the reduction of contact resistance. A fuel cell separator comprises a separator substrate on which gas channel ribs are formed through vapor-phase growth of a carbon-based porous material with a nanosize structure. An electrode structure for a fuel cell, methods of manufacturing the separator and the fuel cell, and a solid polymer fuel cell comprising the electrode structure.
