| Abstract: | Three-dimension straight channel models of anode and cathode were established by using CFD method. Output performance was validated with 500W PEMFC stack. Effect of pressure,stack temperature and humidification temperature on output voltage were analyzed. Based on the results of simulation,the effects of pressure and temperature on distribution of reaction gas and current density were studied. This work can provide some help in improving output performance and working stabilization of vehicle PEMFC. |
