ABSTRACT:
A separator for a fuel cell includes a main separator and a sub separator. A plurality of intake manifolds and exhaust manifolds are perforated on both end portions of the main separator and the sub separator. A plurality of channels are formed on an upper surface of the main separator so that fuel is supplied through the different intake manifolds and is exhausted through the different exhaust manifolds. Auxiliary channels are formed on a lower surface of the main separator and an upper surface and a lower surface of the sub separator so as to connect the intake manifolds and the exhaust manifolds to the channels. A connecting channel is formed on a lower surface of the main separator so as to communicate with the channels, and connect the channels and the auxiliary channels.
