Analysis of the reaction process in solid oxide direct carbon fuel cell anode

    摘要
  • 摘要: 以氧化钇稳定的氧化锆(YSZ)为电解质组装成直接碳燃料电池(DCFC),分别以活性炭(AC)、石墨(G)、神府半焦(SC)作为DCFC燃料,研究了碳燃料的特性、电池操作温度以及阳极反应气氛等对DCFC阳极反应过程的影响。结果表明,三种碳燃料在空气、CO2气氛中氧化反应活性顺序为AC > SC > G,当三种碳材料作为DCFC燃料时,活性炭作为燃料的DCFC性能最好,半焦燃料次之,石墨作为燃料的DCFC性能最差,而且燃料反应活性与其表面含氧官能团、孔隙结构有关;DCFC的阳极反应过程存在碳燃料直接氧化为CO2、CO2与C反应转化为CO,以及CO氧化为CO2等。

     

    Abstract: A direct carbon fuel cell (DCFC) was assembled with yttria stabilized zirconia (YSZ) as electrolyte and active carbon (AC), graphite (G) and semi-coke (SC) were employed as the DCFC fuels. The influences of the carbon fuel pore structure and reactivity, operation temperature, anode atmosphere on the anode reaction were investigated. The results indicated that for three carbonaceous fuels, the performance of DCFC is in the order of AC > SC > G, the same as that for their oxidation reactivity in air or CO2 atmosphere. The reactivity of carbonaceous fuels is determined by their surface oxygenic functional groups and pore structure. Moreover, the results revealed that the DCFC anodic reactions involves the oxidation of C to CO2, the conversion of CO2 to CO via the reverse Boudouard reaction, and the oxidation of CO to CO2.
