燃料电池车作为新能源汽车的一种,以其续驶里程长、动力性能高、燃料加注快、兼容可再生能源等特点,得到愈来愈广泛的重视。燃料电池堆是燃料电池汽车的核心,其比功率是反应燃料电池堆技术水平的重要指标,掌握高比功率燃料电池电堆技术可以降低电堆硬件数量,从而也会使电堆成本得到大幅降低。国际上先进的燃料电池堆由于具有高的比功率使其在车辆有限空间能提供较大功率,满足了车辆动力需求;然而,国内目前电堆比功率相比国际先进水平还有一定差距,针对这一问题,本文从高活性催化剂、增强复合质子交换膜、高扰动流场、导电耐腐蚀薄金属双极板、电堆组装与一致性等多方面,探讨了提高燃料电池电堆比功率的技术途径,基于理论与实践积累分析了燃料电池活化极化、欧姆极化及传质极化与材料、部件、组装的关联性,为进一步提高燃料电池堆性能与比功率提供方向性参考。

Fuel cell vehicles, as the most promising clean vehicle technology for the future, represent the major chances for the developing world to avoid high-carbon lock-in in the transportation sector. In this paper, by taking China as an example, the unique advantages for China to deploy fuel cell vehicles are reviewed. Subsequently, this paper analyzes the greenhouse gas (GHG) emissions from 19 fuel cell vehicle utilization pathways by using the life cycle assessment approach. The results show that with the current grid mix in China, hydrogen from water electrolysis has the highest GHG emissions, at 3.10 kgCO2/km, while by-product hydrogen from the chlor-alkali industry has the lowest level, at 0.08 kgCO2/km. Regarding hydrogen storage and transportation, a combination of gas-hydrogen road transportation and single compression in the refueling station has the lowest GHG emissions. Regarding vehicle operation, GHG emissions from indirect methanol fuel cell are proved to be lower than those from direct hydrogen fuel cells. It is recommended that although fuel cell vehicles are promising for the developing world in reducing GHG emissions, the vehicle technology and hydrogen production issues should be well addressed to ensure the life-cycle low-carbon performance.

根据使用过程特征,可以将用能行为分成生产领域用能与消费领域用能。前者提供产品,后者提供服务。消费领域与生产领域用能存在不同特征,其评价方法、节能途径、战略政策等也存在差别。考虑到这一领域能耗可能是我国下一阶段能耗增长点,在节能领域需要对其给予足够的重视。本文在分析消费领域用能特征的基础上,提出对其的衡量方式和节能途径,并针对我国目前消费领域用能的现状给出建议。
