Abstract:

Air-cooling PEMFC, that is of some advantages such as simpler structure, lower energy consumption and so on, has good potential for the application in the fields of portable power sources.In this paper, the experiments are designed to study the effect of load and environment temperature on the operation temperature of PEMFC stack, and to find out that of operation temperature and humidity on its output performance.A model based on genetic algorithm is established for temperature characteristic, and fuzzy-PID fusion control algorithm is used for the design of temperature controller.And finally, to make sure the optimum performance of PEMFC stack output, several different modes are adopted to control the cycle of exhaust emission, according to the humidity features at various output current.
