    • 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.
    • 本文公开了一种清洗燃料电池的方法,通过打开和关闭吹扫阀,存在于燃料电池堆中的水与气体一起排出燃料电池堆外,包括:使用吹扫进行短时间吹扫数次 阀; 并使用吹扫阀进行长时间吹扫一次,其中重复进行短时间吹扫和长时间吹扫。 吹扫燃料电池的方法的优点在于,使用吹扫阀进行几次短时间的吹扫,然后进行长时间的吹扫一次,并且重复进行这些短时间的吹扫和长时间的吹扫 因此,能够解决只进行短时间吹扫或只进行长时间吹扫时发生的问题,能够提高燃料电池的效率和性能,能够稳定地进行燃料电池的运转。
