摘要
以活性炭颗粒和柔性石墨颗粒为原料,聚四氟乙烯(PTFE)为粘结剂,制作微生物燃料电池电极。在进行压制试验和烧结试验的同时,讨论烧结电极的强度、亲水性、电导率和孔隙率,得出最佳条件:PTFE浓度为30%,PTFE与乙醇质量比为4∶1,烧结温度为380℃,保温4 h,200℃以下时的升温速度为80℃/h,200℃以上时为60℃/h,随炉冷却降温。
Based on particles of activated carbon and flexible graphite as raw materials, polyte- trafluoroethylene （PTFE） for binder, microbial fuel cell electrodes were made. While suppress test and sintering experiment proceed,intensity, hydrophilic,electric conductivity and porosity of sin- tering electrode were discussed,and the optimal conditions were obtained：the concentration of PTFE was 30%, the ratio of PTFE to ethanol was 4：1, the temperature of sintering was 380℃, insu- lation for 4 h, the heating-up temperature was 80℃/h below 200℃, otherwise 60℃/h above 200℃. temoerature decreased with furnace cooling.
