摘　　要：车载燃料电池水热管理不仅涉及温度的优化控制,更是综合考虑热场,化学场,电场,流场,压力场,组分运输等多尺度,多物理,多过程的场流固耦合的多形态,多相,多工况下传热传质的动态的集成优化与协同控制。为了寻求保持燃料电池水热平衡并提高电池性能和寿命的关键技术,本文采用CFD仿真技术针对燃料电池的水热管理即对水–气体–质子三相界面上发生的水分生成与传输和热量传递等的空间分布和时间分布展开了研究分析。The water and heat management of PEMFC not only involves the optimization of temperature control, but also synthetically considers the thermal field, chemical field, electric field, flow field, pressure field, component transport and so on, which is a dynamic integrated optimization and cooperative control method that takes multi-scale, multi-physics, multi-process, fluid-solid-interaction, various-form, multiphase, multiple working-condition calculation into consideration. In this paper, CFD simulation technology is applied in analyzing the liquid and thermal management of PEMFC in search for key technology to keep the liquid and thermal balance in the fuel cell, which researches the spatial distribution and time distribution of the water production, transport and heat transfer on the water-gas-proton three-phase interface.
