聚合物电解质燃料电池电动车辆（PEFCV）的燃料处理器子系统中研究较多的一个是一氧化碳清除步骤。目前，研究工作致力于开发一种系统，该系统能够在PEFC可接受的水平下（特别是在瞬态响应中）减少从重整器流出的流中的CO量。一个单元，作为后过滤器的CO优先氧化（PROX），基于CO和CuCl之间的可逆络合物的形成和解离反应，能够克服PROX的主要限制（瞬时冷启动和动态去除重整生成油中的CO小于10 ppm）进行了分析。本研究的实验方法考虑了不同载体（Al 2 O 3，碳，SiO 2）的筛选和最佳操作条件（温度，压力，GHSV，吸附/脱附时间）的识别。
One of the more investigated fuel processor subsystems, for polymer electrolyte fuel cell electric vehicles (PEFCV), is the carbon monoxide clean-up step. At present, the research efforts are addressed to develop a system able to reduce, at level acceptable for PEFCs (particularly in transient response), the amount of CO in the stream outgoing of the reformer. A unit, working as post-filter of the CO preferential oxidation (PROX), based on the reversible complex formation and dissociation reaction between CO and CuCl, able to overcome the main limits of the PROX (instantaneous cold-start and dynamic removal of CO in reformate to less than 10 ppm) has been analyzed. The experimental approach of this study has regarded the screening of different supports (Al2O3, carbon, SiO2) and the identification of optimal operating conditions (temperature, pressure, GHSV, adsorption/desorption time).
