四流道蛇形结构质子交换膜燃料电池温度分布数值模拟
Temperature distribution simulation of fourport serpentine flow field PEMFC
摘要
Abstract
In order to study the temperature effect on the performance of the PEMFC,this thesis has performed numerical stimulation of four-port serpentine flow field PEMFC with different temperature by applying the analyzing software—COMSOL Multiphysics which can directly couple multiple physical fields.The study has shown the temperature changes of the vertical membrane electrode,The cell center when flowing from anode through membrane to cathode under the same operating condition.Moreover,it has shown the temperature changes of the entrance,center and exit of the cell while flowing from anode to the corresponding position of cathode when the temperature of cell is kept as 353K.The following can be analyzed and compared from the result of the stimulation:the rising of the cell's inner temperature has linear changing relationship with the original temperature itself.The temperature of the cell's entrance,center and exit are different.In the light the above consideration,the temperature rising of the cell entrance is the highest,while the center lower and the exit lowest.The cell heat generated from the internal response decreases with the rising of temperature.The simulation results has great significance on the optimization of PEMFC performance.关键词
