摘要
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已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口处测得温度,利用灰色系统解决“小样本”、“贫信息”不确定性问题的特点,建立预测尾气温度的新型数学模型,对下一时刻的出口温度进行预测,并根据预测的数据对风扇功率进行预调节,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,此模型已达到较好的预测精度,并且由于程序的简单,较容易在硬件上实现,具有较高的实用性。
Proton exchange membrane fuel cell （PEMFC） generates large amount of heat when it runs, so whether the heat can be expelled in time is a key reason for commercializing PEMFC. A new-style mathematic model integrated with grey system was developed to forecast the temperature of PEMFC, and input parameter of it is the temperature of expelled air measured by a temperature sensor. Then the power of fan can be adjusted according to the forecasted temperature and PEMFC can work at fitting temperature. This model has well precision by analysis of experiment data, and this method has well practicability because of simple program and facile actualization in hardware.
