| 摘 要： | 质子交换膜燃料电池(PEMFC)通常在为电动车提供电力的同时,也要产生相当数量的废热(约40%～60%)。为了提高质子交换膜燃料电池混合电动车的能量利用率,提出了将温差发电机作为PEMFC的废热回收装置,使其能利用PEMFC低品位的热能进行二次发电并用于锂电池的在线充电。通过对该热电联供系统的热力学分析,得出了温差电池在PEMFC不同运行温度下的发电功率。试验结果显示,此系统可以在提高能量综合利用率的同时,降低对车载锂电池尺寸的设计要求。

| Abstract: | Generally,proton exchange membrane fuel cell (PEMFC) produces a considerable amount of waste heat (approximately 40%-60%) as it generates electricity for powering electric vehicle.To improve overall efficiency of the PEM fuel cell hybrid electric vehicle,a method to recover the heat from PEMFC by a thermoelectric generator (TEG) was presented and a second-hand electricity was generated which is used for online charge of Li battery.The generation power of thermoelectric cell under different temperatures was ... |
