Electromotive Force for Solid Oxide Fuel Cells Using Biomass Produced Gas as Fuel

当燃料用一个内部计算机节目在 700-1,200 K 被计算，用生物资源的稳固的氧化物燃料房间的起电的力量(e.m.f ) 生产了气体(BPG ) ，基于热力学的平衡分析。旅游节目也在燃料房间以及象 H 2, 公司，公司 2 和 CH 4 那样的平衡种类的集中预言氧的集中。与把氢用作燃料相比，为把 BPG 用作燃料的房间的 e.m.f 是由碳免职低、强烈影响的亲戚。移开碳免职， H 2 增加的 O 在各种各样的操作温度被决定。进一步，为房间的 e.m.f 基于氧化钇稳定了氧化锆并且当电解质被比较，做了 ceria。因为电解质是相对小的，当与那相比使用氧化钇稳定了氧化锆时，学习表明当把 BPG 用作燃料时，为使用的 SOFC 的 e.m.f 的消沉做了 ceria。

The electromotive force （e.m.f.） of solid oxide fuel cells using biomass produced gas （BPG） as the fuels is calculated at 700-1,200 K using an in-house computer program, based on thermodynamic equilibrium analysis. Tour program also predicts the concentration of oxygen in the fuel chamber as well as the concentration of equilibrium species such as H2, CO, CO2 and CH4. Compared with using hydrogen as a fuel, the e.m.f. for cells using BPG as the fuels is relative low and strongly influenced by carbon deposition. To remove carbon deposition, the optimum amount of H2O to add is determined at various operating temperatures. Further the e.m.f, for cells based on yttria stabilized zirconia and doped ceria as electrolytes are compared. The study reveals that when using BPG as fuel, the depression of e.m.f, for a SOFC using doped ceria as electrolyte is relatively small when compared with that using Yttria stabilized zirconia.
