Abstract
A fuel cell according to the present invention comprises a membrane electrode assembly, a bipolar plate for guiding a reaction gas to the membrane electrode assembly, two layers of coolant flow fields formed on the bipolar plane opposite to another plane on which a reaction gas flow field is formed, and an interlayer separation plate; wherein the interlayer separation plate separates the two layers of coolant flow fields and has permeability or jet orifices so as to allow a coolant to pass through.
