摘要
为了深入研究质子交换膜燃料电池加湿器的工作性能,从传热传质学的角度分析膜加湿器系统,建立加湿器的机理模型。当已知加湿器入口气体和水流的状态参数(如:温度、流量、压力)以及加湿器的物理参数(如:气道的几何形状和热传导系数等)时,此模型可以计算出加湿器出口气体的相对湿度、温度以及出口水温等变量值。以1 kW质子交换膜燃料电池的参数为依据,用Simulink进行仿真。仿真结果与实验数据的比较表明,模型能够反映出加湿器的实际工作状况。
A theoretical model for a humidifier of PEM fuel cell systems was developed and analyzed based on the theory of heat transfer and mass transfer, which is intended to be used for the investigation of the performance of a humidification system. A general calculation methodology was developed to implement this model. Knowing a set of gas feeding condit.ions （i.e., pressure, temperature, flow rate） and physical conditions of a humidifier （i.e., channel geometry, heat transfer coefficients, etc. ）, the model could provide informfion regarding the relative humidity and temperatures of outlet gases, as well as the temperature of outlet water. Using the parameters of I kW PEM fuel cell system, the proposed model was implemented in Simulink environment. The simulation results showed good agreement with the performance of the test bench.
