SEPARATOR FOR FUEL CELL HAVING IMPROVED FLOW FIELD AND FUEL CELL USING THE SAME

摘要

PURPOSE: A separator for a fuel cell and the fuel cell using thereof are provided to enlarge the contacting area between fuel and an electrode by improving the structure of a channel. CONSTITUTION: A separator(100) for a fuel cell including a channel comprises more than two spaces with different patterns of the channel. The number of curve change point where the progressive direction of the channel changes, increases by the distance between an inlet and an outlet of the separator. The pattern of the channel includes a serpentine shape, an interdigited shape, a parallel shape, and an island shape.
