Abstract: A cooling path structure for reducing the flooding of a fuel cell is provided to reduce the flooding by preventing the over cooling of the reactive gas and to improve the performance of a fuel battery by maintaining the temperature of an outlet of reactive gas over the stack temperature. A separator of a Polymer Electrolyte Membrane Fuel Cell(PEMFC) comprises (a) a hydrogen separator formed with a hydrogen path, (b) an air separator formed with an air path, and (c) a cooling path removing the heat of reaction, which is formed between the hydrogen separator and the air separator. The cooling path(26) is not formed at a part overlapped with an outlet path of reactive gas and an inlet path of cooling water and is expanded to the whole separator on a basis of the outlet of reactive gas. Therefore, the outlet of the reactive gas is not over-cooled with the cooling water.
