| 中文摘要 | 对70kW常压质子交换膜燃料电池堆氢气膜增湿系统的传热传质特性进行了实验研究。管壳式膜增湿器应用于大功率燃料电池堆氢气增湿系统具有增湿速率快、被增湿氢气润湿程度好的优点。利用液态水对氢气进气进行增湿,实验中被增湿后氢气总能够达到过饱和状态,氢气流量一定时,膜增湿器增湿水进出口温差随水流量增大而降低,氢气出口温度随着液态水流量升高而接近增湿水进口温度;增大增湿水流量能够降低增湿水通过膜增湿器前后温差。增湿水温度和流量一定时,燃料电池堆负荷增大,被增湿氢气出口相对湿度变化不明显。; Heat and mass transfer of low pressure 70 kW proton exchange membrane fuel cell stack hydrogen membrane humidifying system is experimentally studied. When the tube shell type membrane humidifier is applied to large power fuel cell stack external humidifying system,mass transfer of water is rapid and hydrogen inlet is well humidified when liquid water is used to humidify hydrogen. Hydrogen outlet is always saturated during experiment. Temperature of hydrogen outlet approaches humidifying water better as water flow rate increases. As water flow rate increases,temperature loss of humidifying water decreases. When water flow rate is definite,hydrogen outlet dew point dose not change much as fuel cell engine load increases. |
