Abstract
A method and a system for optimizing a lifetime of a fuel cell system based on adjustment and constraint of a thermoelectric ratio are provided. The method includes obtaining initial reference voltages of a plurality of single-machine fuel cell systems, and performing a durability test under a normal operating condition to obtain variation relationships of reference voltage over time; monitoring an operating voltage of each of the single-machine fuel cell systems in real-time under the normal operating condition to obtain a real-time monitored voltage and a real-time voltage deviation; calculating a performance expected attenuation profile of each of the single-machine fuel cell systems under the normal operating condition; obtaining current density distribution and actual available heat of each of the single-machine fuel cell systems, and calculating a health state boundary of each of the single-machine fuel cell systems in stable operation, so as to optimize operating modes of the systems.
