摘要
质子交换膜燃料电池温度控制系统设计时以满足高环境温度和高负载等极端工况下的散热需求为目标,常忽略了在低温以及低负载下温度控制的稳定性;为了提高在低环境温度下、低负载下温度控制系统对燃料电池温度控制的稳定性,在传统的PID控制的基础上,改进了控制策略,有效提升了燃料电池在低环境下低负载时温度的稳定性,对提高燃料电池性能与耐久性有积极影响。
The temperature control system of the proton exchange membrane fuel cell is designed to meet the heat dissipation requirements under extreme conditions such as high ambient temperature and high load.The stability of temperature control at low temperatures and low loads is often ignored.To improve the stability of the temperature control system for fuel cell temperature control under ambient temperature and low load,based on the traditional PID control,the control strategy is improved,which effectively improves the temperature stability of the fuel cell under low environment and low load,which has a positive impact on improving fuel cell performance and durability.
