摘要
研究以氧化铈(CeO2)作为直接硼氢化物燃料电池(DBFC)阴极催化剂的性能.结果表明:氧化铈对氧还原具有良好的催化效能,但对BH4-离子水解没有明显的促进作用,而且还能抑制它在正极的氧化.以氧化铈为阴极催化剂组装成的模拟单室燃料电池在常温下的最高功率密度为67.8mW·cm-2,运行稳定.
The performance of CeO2 as oxygen reduction electrocatalyst in direct borohydride fuel cell was investigated. The experimental results indicate that CeO2 shows significant electrocatalytic performance for oxygen reduction and exhibits no observed promotion effect on hydrolysis or electro-oxidation of BH4^-. The power density of experimental one-compartment fuel cell with CeO2 as cathode electrocatalyst can reach a 67.8 roW. cm^-2 at room temperature.
