Air-Cooling PEMFC stack possesses some advantages, such as simpler structure, lower energy consumption and so on, which emerges as a potential application for the potable power source in the research. In all of stack operating conditions, the stack operating temperature and humidity are the key factors which affect the stack output performance. In this paper, the air-cooling PEMFC stack＇s temperature and humidity characteristic were researched by experiments. The effects of stack operating temperature and emission cycle on the output performance were analyzed through experiments data. Then the stack temperature and humidity experience model were derived from the results based on genetic algorithms. The research results are useful to analyze air-cooling PEMFC stack＇s temperature characteristic, optimize model and design real time control system.
