摘　　要：利用Matlab/Simulink软件搭建燃料电池发动机低温起动仿真模型,对FCE不同低温起动方法的特点和可行性进行了分析,对无辅助措施电堆起动过程、3种带控制策略的电堆低温起动过程、FCE冷却系统加热电堆起动过程的仿真结果进行了分析,得出对FCE采用保温和冷却系统加热的联合控制策略,可使FCE低温环境下顺利起动;采用第2控制策略,可使电堆自身的温度维持在70-80℃,从而使FCE的工作特性最佳、输出效率最高。对FCE冷却系统加热的试验与仿真结果进行对比分析,试验和仿真的结果基本吻合。The cold-start simulation model of fuel cell engine（FCE） was built by Matlab/simulink software. The characteristic and feasibility of different cold-start methods were analyzed for fuel cell engine. The cold-start processes were simulated and analyzed for the cold-start stack without auxiliary measures, the cold-start stack with three control strategies, the cold-start by heating the coolant system of FCE. It shows that the combined control strategy makes fuel cell engine start successfully under freezing environment. By adopting heat insulation and the coolant system heated with the control strategy. The stack＇s temperature is able to hold 70-80 ℃ and the characteristic and efficiency is best. The experiment and simulation results were compared and analyzed for the coolant system heated, and their results fit basically.
