Abstract：
 The invention relates to a method to fast appraise vehicle fuel battery service life, which includes the following step: 1.definie the fuel cell performance drops how much to the life end; 2. carry on fuel cell gantry experiment, definite fuel cell performance descending rate along with loading times, descending rate along with start and stop times, descending rate along with idle rate time; 3. carry on the statistics of the fuel cell situation in actual use process, the states statistical content includes the average each hour large scale loading times, average each hour starts and stops times and average each hour idle rate times; 4. carry on the computation of the 1-3 step results according to the invention method formula. The invention method reflected the influence each kind of key influence factor on the fuel cell life in the use process, can obtain the fuel cell usable life in the shorter run time within 150 hours.
