The pressurized 3, 600cm2 cells have been tested to survey life time under elementary practical operation patterns, which have involved start/stops and load changes in the continuos rated operation. According to test, it has been discovered that approximate formulas between voltage changing velocity and generation time can be obtained for operating temperature and operation patterns. By utilizing such formulas, we can calculate the influences of the continuous rated operation, start/stop and load change. Furthermore, we can calculate accelerate ratio of cell life to operating temperature.
