Predicting Methods of Fuel Cell Life (Integral Method)

Abstract

For a predicting method of the fuel cell life which accompanies with continuous rated operation, start/stops and load changes, we propose the Integral Method. In this method, we seek for approximate formulas of voltage changing velocity to the generating time, and we can calculate voltage drop by integrate approximate formulas for operation patterns or operating temperature. This method allows us to separate the influences of the continuous rated operation, start/stop and load changes, so it comes to estimate cell life accurately.
