质子交换膜燃料电池组工作时，产生大量热量，能否确保质子交换膜燃料电池的废热及时排出己成为其能否实用化的关键之一。直接采用温度传感器在质子交换膜燃料电池的尾气出曰处测得温度，利用灰色系统解释‘小样木”、“贫信息”不确定性问题的特点，建立顶测尾气温度的新型数学模型，对卜一时刻的出曰温度进行顶测，井根据顶测的数据对风扇功率进行顶调节，确保质子交换膜燃料电池工作在适宜的温度中。通过对实验数据的分析，此模型己达到较好的顶测精度，井且由于程序的简单，较容易在硬件上实现，具有较高的实用性。-proton exchange membrane fuel cell group work, produce a large amount of heat be able to ensure that the proton exchange membrane fuel cell waste heat emitted in a timely manner has become his ability to practical use one of the keys. Temperature sensors used directly in proton exchange membrane fuel cell exhaust out Says Agency measured temperature, Gray explained the use of 'wooden galley proof "," poor information "uncertainty characteristics, Top test to establish a new type of exhaust gas temperature mathematical model of a moment of the BU out Says Top temperature measurement Well according to the data measured top of the fan power for the top-conditioning, ensure proton exchange membrane fuel cells work in the appropriate temperature. Based on the analysis of expe
