The present invention provides a method for removing residual water in a fuel cell, which controls the humidity of purge gases to effectively remove residual water in the fuel cell and to maintain the humidity in a membrane at a constant level, thus ensuring the durability of the membrane. For this purpose, the present invention provides a method for removing residual water in a fuel cell, characterized in that the relative humidities of purge gases supplied to an anode and a cathode are controlled to selectively reduce water content in the fuel cell and water content in a membrane.

Method for removing residual water from fuel cell

The present invention provides a fuel cell bipolar plate in which an air gap or a material layer having a heat transfer coefficient lower than that of the bipolar plate is provided so as to reduce total amount of liquid water generated in a fuel cell, thereby preventing the occurrence of flooding and reducing the time required for cold start, enhancing durability, decreasing parasitic purge requirements, and enhancing operational stability.
