本文介绍了大连化学物理研究所燃料电池工程中心所研制的PtRu/C和PtRu-HxWOy/C两种抗CO催化剂的制备和表征结果,PtRu-HxWOy/C采用复合载体法制备.当以含CO的燃料操作时,所研制的抗CO催化剂制备电池的性能明显高于Pt/C制备的电池.开发了一种复合结构的抗CO电极,这种电极具有良好的抗CO能力.用这种结构的电极组装的5-kW电池组以甲醇重整气为燃料时表现出良好的性能.
CO tolerance electrocatalysts of PtRu/C and PtRu-HxWOy/C were prepared and characterized.A composite support method was applied to prepare PtRu-HxWOy/C.The performances of cell made of the CO tolerance catalysts were much higher than that of Pt/C when CO containing fuel was applied.A composite structure electrode was developed,and showed good CO tolerance.At last a 5-kW PEMFC stack equipped with the composite structure electrodes was operated with methanol reforming fuel,and showed good performance.
