甲醇燃料电池高性能催化剂

Development of High Performance Catalyst for Direct Methanol Fuel Cell

燃料电池作为一种清洁高效的能源,被认为是解决未来能源短缺和环境问题的希望,其中,应用于便携式电子设备和新能源汽车的直接甲醇燃料电池得到广泛关注。本文利用静电纺丝技术制备了C-CeO_2纳米纤维,作为一种铂钌催化剂载体,应用于直接甲醇燃料电池。研究发现以制备的纳米纤维为载体的PtRu/(C-CeO_2)NF催化剂其性能优于目前广泛使用的PtRu/Ccom催化剂,甲醇氧化还原活性提高了3倍以上,这主要由于催化剂中的二氧化铈所起的作用。

Fuel cells are often portrayed as the answer to the world's pressing need for clean, efficient power. Direct methanol fuel cell (DMFC) is now being considered as an attractive power source for portable power and electric vehicle application. In this study, C-Ce〇2 nanoflbers were prepared by electrostatic spinning technology. As a platinum ruthenium catalyst carrier, they were used in direct methanol fuel cell. The results showed that the performance of PtRu/(C-CeO2) NF catalyst with prepared nanometer fiber as the carrier was superior to widespread used PtRu/Ccom catalyst, methanol oxidation reduction activity was improved by more than three times.
