本文研究了制造两种类型的固体氧化物燃料电池 (SOFC) 系统对环境的影响。管状 SOFC（基于 100kW 西门子-西屋设计）和平面 SOFC（基于 1kW Sulzer 设计）。使用不同程度的细节，对两个系统的 PEN 和互连制造、工厂平衡和前体材料生产对环境的影响进行了评估。结果表明，用于制造设备和燃料电池的材料的生产和供应在与所研究的每个燃料电池系统相关的总体环境负担中占很大一部分。尽管如此，与制造阶段相关的总排放量仍然只占两种燃料电池寿命周期二氧化碳排放量的额外 1%。制造阶段对其他几种受管制污染物的相对贡献较高，但这反映了与使用阶段的 SOFC 相关的较低水平，而不是表明制造阶段产生了重大负担。有人提出，报废再利用或回收可以在进一步减轻环境负担方面发挥关键作用。
This paper examines the environmental impact of manufacturing two types of solid oxide fuel cell (SOFC) system. The tubular SOFC (based on a 100kW Siemens–Westinghouse design), and the planar SOFC (based on a 1kW Sulzer design). Using different levels of detail, the environmental impact of the manufacture of the PEN and interconnect, the balance of plant and the production of precursor materials has been assessed for both systems. The results demonstrate that the production and supply of materials for the manufacture of both the balance of plant and the fuel cell are responsible for a significant share of the overall environmental burden associated with each of the fuel cell systems studied. Nonetheless, the total emissions associated with the manufacturing stage still only contribute an additional 1% to lifetime CO2emissions for both fuel cell types. The relative contribution arising from the manufacturing phase to several other regulated pollutants is high, but this reflects the low levels associated with the SOFC in use phase, rather than indicating a significant burden arising from manufacture. It is proposed that end-of-life reuse or recycling could play a key role in further reducing environmental burdens.
