摘要
质子交换膜燃料电池作为氢能产业应用的核心产品,具有能量转换效率高、零排放、无污染等特点,是车用领域的重要动力来源之一.然而,高昂的成本限制了车用质子交换膜燃料电池的大规模应用及推广.低铂化膜电极技术的开发是提高其价格竞争力的重要手段,但低铂化过程中面临的严重传质和寿命问题急需解决.总结了低铂化膜电极技术的研究进展及现有技术的不足,并展望了未来的发展趋势,可为车用质子交换膜燃料电池的低铂化膜电极技术开发提供参考.
Abstract
As the core product of the hydrogen energy industry,proton exchange membrane fuel cells are characterized by high energy conversion efficiency,zero emissions and no pollution.They are one of the most promising power sources in the automotive field.However,the high cost limits the large-scale application and promotion of PEMFCs for vehicles.The development of low-platinum PEMFCs for vehicles is an important technical route to improve cost competitiveness.However,the serious mass transfer and lifespan issues faced in the low-platinum process urgently need to be solved.This paper summarizes the research progress of low-platinum membrane electrode assembly technology and the shortcomings of existing technologies.It also looks forward to the future development trends,providing reference value for the advancement of low-platinum membrane electrode technology for vehicle PEMFCs.
