Abstract
The present invention provides a purge system for a fuel cell, which can reduce the time required to thaw a frozen valve during cold start-up and reduce the whole start-up time, thus improving the cold start performance. In preferred embodiments, the present invention provides a purge system for a fuel cell with improved cold start performance, the system preferably including a main pipe connected to a purge gas outlet of a fuel cell stack to discharge a purge gas purging the fuel cell stack and impurities; an auxiliary pipe branched from the main pipe; a purge valve installed in each of the main pipe and the auxiliary pipe to perform an purge operation; a cut-off valve installed at an upstream side of the purge valve in the auxiliary pipe; and a controller for controlling the operation of the purge valves and the cut-off valve.
