摘要： Disclosed herein is a method of purging a fuel cell, by which water present in fuel cell stacks is discharged outside the fuel cell stacks together with gas by opening and closing a purge valve, including: conducting a short-period purge several times using the purge valve; and conducting a long-period purge once using the purge valve, wherein the short-period purge and the long-period purge are repeatedly conducted. The method of purging a fuel cell is advantageous in that the short-period purge is conducted several times using a purge valve and then the long-period purge is conducted once, and these short-period purges and the long-period purge are repeatedly conducted, so that the problems occurring when only a short-period purge or only a long-period purge is conducted can be solved, with the result that the efficiency and performance of the fuel cell are improved and the fuel cell can be stably operated.

摘要： A fuel cell separator, a fuel cell stack having the fuel cell separator, and a reactant gas control method of the fuel cell stack are provided. That is, even when the fuel cell stack operates under the low load operation condition, a reactant gas is supplied to the reactant gas passages of the fuel cell separator, and thus, the length of the passage can be shortened by 50% as compared with the prior art having only one reactant gas passage. Therefore, the reactant gas can be effectively supplied without experiencing pressure loss. Further, in the high load operation of the fuel cell stack, the reactant gas is introduced into the first reactant gas passage of the fuel cell separator and utilized in half of the whole electrode area. Subsequently, the reactant gas is introduced into the second reactant gas passage and utilized in the remaining half of the electrode area. The flow rate of the reactant gas flowing along the passage channels is increased by two times, even when the reactant gas utilizing rate is identical as compared with the reactant gas flow in the low load operation. As a result, the moisture existing in the passage channels can be more effectively discharged and the flooding phenomenon occurring in the high load operation can be prevented. By controlling the reactant gas supply in accordance with an operation condition of the fuel cell stack without experiencing pressure loss and deterioration of the utilizing rate, the flooding phenomenon and concentration polarization phenomenon that occur in the fuel cell stack can be prevented.

摘要： The present invention relates to a sealing structure for polymer electrolyte fuel cell, which comprises a bipolar plate with sealing groove to be filled with rubber using a dispenser, and a gasket interposed between the bipolar plate and a membrane electrode assembly. That is, according to the present invention, the thickness deviation in a gasket can be softened by interposing a gasket between a rubber ands a membrane electrode assembly after filling rubber in a sealing groove formed on a bipolar plate using a dispenser. Also, nonuniform stress distribution can be resolved because a gasket covers with a pressure despite the height deviation of rubber, and a stress is not directly transmitted to a membrane electrode assembly and dispersed by a gasket despite nonuniform stress distribution.
