Abstract: A fuel cell having a multilayered separator is provided to prevent the flooding of main channels and to improve the uniformity of the transfer pressure of main channels and the uniformity of humidity distribution of a separator. A fuel cell comprises a plurality of unit cells, and separators(100) which are inserted between the unit cells to separate the each unit cell, wherein the separators comprises a pair of separators(110) for main channels where a plurality of main channels(112) of linear shape penetrate and which have a discharge hole(114) for discharging the liquefied water at the both sides of the main channels; and a separator(120) for an auxiliary channel which is inserted between the pair of separators for main channels so as to be closely adhered to the separators for main channels, and is provided with microchannels(122) having the width narrower than the main channels and transferring the liquefied water at the both surfaces.

Abstract: A separator of a fuel cell is provided to secure a space that enables reaction fluid to flow without clogging channels in various operation conditions, promote the diffusion of the fluid into a catalytic layer, and discharge excessive water generated from a cathode effectively. A separator(10) of a fuel cell which supports a membrane-electrode assembly has fluid inlets(26) at one end, fluid outlets(27) at the other end, and main channels(20) as extended grooves, which are formed on the surface of the separator. At least one inner channel(30) is formed along the main channel. The inner channel has a width narrower than that of the main channel and gets in contact with the main channel with the surface open.
