The results show that when the cathode humidified temperature increase, the humidification of membrane and fuel cell performance improved at lower current density, while the saturation in diffusion layer increase and the performance decreases at higher current density. Humidification of membrane and fuel cell performance improved when the anode humidified temperature increase, the saturation in diffusion layer decrease and fuel cell performance improved when the fuel cell working temperature increase, the resistance of diffusion layer decrease and the performance improved when the porosity largen. At last, the simulation results are compared with the experimental results and they are basically the same.

OR＞1 indicates dangerous factor, OR＜1 protective factor, and OR=1 no significance. The results showed that if triglyceride and very low density lipoprotein cholesterol increased an average level of normal respectively, and there would be OR of TG 2.43 (P＜0.05) and OR of VLDL-C 6.09 (P＜0.05), the high levels of TG and VLDL-C were the factors of lithogenesis. High density lipoprotein cholesterols (HDL1-C, HDL2-C, HDL3-C), with OR less than one, were the factors of protecting against the formation of gallstone.

结果：甘油三酯和极低密度脂蛋白胆固醇每增加一个正常均值水平，OR值分别是2.43(P＜0.05)和6.09(P＜0.05)，是重要的致石因素指标；高密度脂蛋白胆固醇(HDL1-C、HDL2-C、HDL3-C)，OR值均低于1，是重要的防石因素指标；低密度脂蛋白胆固醇和总胆固醇的OR值均小于1，本研究结果提示其可能是一种代谢状态而非保护因素。
