Abstract

A cold start control method for a fuel cell is provided. The method includes determining whether a cold start condition upon start on is satisfied and estimating thawing energy required to thaw frozen moisture inside a fuel cell stack when the cold start condition has been satisfied. A thawing control SOC of a high-voltage battery is calculated based on the estimated thawing energy. The cooling water inside a cooling water line for cooling the fuel cell stack is heated by using a heater having received power from the high-voltage battery when the current SOC of the high-voltage battery is equal to or less than a thawing control SOC.
