摘要： 选择甲烷蒸汽重整催化剂用于直接内重整熔融碳酸盐燃料电池 (DIR-MCFC) 中, 并考察了 DIR-MCFC 的性能, 讨论了电池放电量、气体压力、燃料气进料水/碳比 (S/C) 等因素对该催化剂性能的影响. 结果表明, 重整催化剂能够满足电池放电需求; 放电量大小影响电池内的 H2 含量, 但对 CH4 含量影响不大; 当气体压力为 0.36MPa 时, 电池内的 H2 含量最大; S/C 越低, 电池性能越高, 相同放电量下, S/C = 1 时的电池电压比 S/C = 2 时的高.

Abstract: A methane steam reforming catalyst was selected by the comparison of its catalytic properties and resistance to carbon deposition. The performance of a molten carbon fuel cell (MCFC) using this catalyst was studied. The effect of discharge magnitude, gas pressure, and steam-carbon ratio (S/C) on the catalyst was also investigated. The results indicated that the catalyst could make the cell perform well, and the increment of the current affected the content of H2 in the cell, but it had minor effect on the content of CH4. In addition, the reforming reaction depended on the gas pressure. There was a maximal content of H2 in the cell at 0.36 MPa. With the decrease of S/C, the performance of MCFC was improved.
