| 摘 要： | 直接硼氢燃料电池(DBFC),是一种新型的高比能便携式电源,其电池电势(1.64 V)及理论比能量(9 300 Wh/kgNaBH4)均高于直接甲醇燃料电池.为了实现BH4-的8电子完全氧化,分别以Ketjen炭黑、Vxc-72R炭黑为载体,采用溶胶-凝胶法制备了纳米级的Au/C催化剂,并采用分层装配的方法组装了单电池,考察了催化剂载体及载体处理对电池性能的影响.结果表明,溶胶-凝胶法是制备纳米级高分散Au/C催化剂的有效方法,Ketjen炭黑载体明显优于Vxc-72 R炭黑,载体经酸处理后可大大提高电池的性能.

| Abstract: | Direct sodium borohydride fuel cell(DBFC) is a new type of portable power sources.Both of its cell potential(1.64 V) and power density(9.3 Wh/g NaBH4)are higher than direct methanol fuel cell.In order to realize the electo-oxidation of BH4-in 8 e completely,Au was used as catalyst,Ketjen carbon and Vxc-72R carbon were used as catalyst carriers with pretreatment or not.The nano-size Au/C catalysts were prepared by the method of sol-gel.Single DBFCs were assembled using Au/C catalysts as anode to research the... |
