摘　　要：以多聚甲醛为还原剂用液相还原法制备了直接甲醇燃料电池(DMFC)用的碳载Pt(Pt/C)催化剂.结果表明,由于制得的催化剂中Pt晶粒的平均粒径小,结晶度低,因此对甲醇氧化的电催化性能优于商品化的E-TEK公司的Pt/C(Pt/C-E)催化剂和以甲醇为还原剂制得的P/C(Pt/C-M)催化剂.In this paper, the Pt/C catalyst used in the direct methanol fuel cell was prepared with the liquid reduction method using paraformaldehyde as the reducing agent. The results indicated that because the average size the crystal particles of Pt the Pt/C catalyst prepared with paraformaldehyde as the reducing agent is small and the crystallinity is low, the electroeatalytic performance of the catalyst for the methanol oxidation of is better than that of the commercial Pt/C catalyst （ E-ETK Co. ） and the Pt/C catalyst prepared with methanol as the reducing agent.
