以Pd-MoO_2/C为阳极催化剂的乙醇燃料电池

Direct ethanol fuel cell with Pd-MoO_2/C as anode catalyst

制备了Pd-MoO2/C作为乙醇阳极催化剂,循环伏安,计时电流测试结果表明该催化剂对乙醇氧化具有良好的活性和稳定性能。制备了以Pd-MoO2/C作催化剂的阳极,与空气电极组装了乙醇燃料电池,采用恒流放电法测试了电池的放电性能。组装了4个单电池组成的电池组,以该电池组负载一个2.5 V 0.3 A的灯泡,在常温下可稳定运行。向电池的阳极槽中添加乙醇,电池可持续放电。

Pd-MoOJC was prepared as catalyst for ethanol oxidation. Evaluated by cyclicvoltammetry （CV） and chronoamperometry （CA）, this material shows excellent activity and stability for the electro-oxidation of ethanol in alkaline media. A direct ethanol fuel cell （DEFC） was constituted with this anode and a self-prepared air electrode. The DEFC shows good performance in constant-current discharging test. A battery with 4-cells was assembled, which could lighten a 2.5 V 0.3 A bulb. Moreover, the battery can discharge continually by adding ethanol into the anode tank.
