| 经过二十余年车用质子交换膜燃料电池技术的研究和突破,目前国际上燃料电池汽车已经进入市场,并成为当前备受瞩目的新能源汽车。然而,由于车况下质子交换膜燃料电池经历复杂的湿度、温度、燃料供应、电流、电压等循环过程,使得燃料电池中关键材料衰减较快,而造成较为棘手的寿命问题。车用燃料电池的寿命问题复杂且涉及面广,本文针对车用燃料电池的启停工况,详实地归纳分析了启停工况下燃料电池的研究过程、衰减机理、实验论证、建模分析,并从燃料电池系统管理角度分析了启停衰减的缓解策略。通过对已有启停工况下质子交换膜燃料电池性能衰减失效的梳理,提出了本文观点、存疑、分析和解释。 |
| 英文摘要: |
| Through the great combined efforts in the last two decades all over the world, the technology of PEMFC (Proton Exchange Membrane Fuel Cell) for automobile application have attained breakthrough, leading to the first market launch of Mirai fuel cell vehicle by Toyota in December 2014. The PEMFC vehicles have become a Green New Energy automobile and obtained extensive attention. However, at the automobile operating mode, PEMFC will suffer various cycles, such as humidification, temperature, fuel supply, current, voltage et al. It will cause the PEMFC key materials degradation and the durability of PEMFC decreases. Thereby the life time of PEMFC is a main obstacle for PEMFC vehicles large-scale diffusion. The vehicle PEMFC lifetime involve massive scale of problems and this review focused on the automobile Start-Stop operating mode. The study approaches, degradation mechanism, experimental verification, modeling analysis of PEMFC under the start-stop operating mode were reviewed in detail. Furthermore, the mitigation strategies were also reviewed from the perspective of fuel cell system management. Finally, some viewpoint, query, analysis and explanation of the problem were provided based on the above review. |
