Beschreibung
Zusammenfassung:	The invention discloses a positive electrode catalyst for a direct methanol fuel cell. The catalyst is composed of, by mass, 5 to 15% of platinum, 40 to 50% of cerium dioxide and 40 to 50% of multi-walled carbon nanotube (abbreviated as MWCNT). The morphology of cerium dioxide is a cube, rod, polyhedron, block or granule. The invention discloses a preparation method for the catalyst. The catalyst has the advantages of low cost and high activity. 本发明公开了种直接甲醇燃料电池的阳极催化剂，该催化剂由铂、二氧化铈和多壁碳纳米管（英文简写MWCNT）组成，各组分在催化剂中所占质量百分数为：Pt:5-15%，CeO:40-50%，MWCNT：40-50%；二氧化铈的形貌为立方体、棒状、多面体、块状或颗粒状。本发明还公开了该催化剂的制备方法。本发明具有低成本、高活性的优势。
