| 摘 要： | 对大功率常压燃料电池系统膜增湿器的传热传质性能进行实验研究,确定了影响膜增湿器性能的主要因素,建立膜增湿器传热传质数学模型,仿真研究了这些因素对膜增湿器性能的影响机制.研究表明,降低增湿器操作压力,增大空气流量,提高进气温度有利于提高扩散系数;减小空气流量和降低干空气进口温度有利于降低膜内水含量梯度.

| Abstract: | Experimental study is conducted on heat and mass transfer performance of high power low pressure fuel cell system membrane humidifier. Main parameters which affect humidifier performance are observed and the mechanism is studied with a humidifier heat and mass transfer model. The results show that low operating pressure and large air flow rate and high inlet temperature help enhancing diffusion coefficient while low air flow rate and low inlet dry air temperature help reducing water content gradient in membrane. |
