Solid Oxide Fuel Cells (SOFCs), known for their high (up to 80%) chemical to electrical/thermal conversion efficiencies, their versatility in fuel intake (hydrogen, natural gas, methanol and other petroleum products etc.) and their relatively environmentally benign operation, have a high market potential, but are not yet mass produced, because of outstanding technological and economic issues.This proposed project aims to address these problems by establishing the feasibility of, and developing, a novel design of SOFC, fabricated using hollow fibres, thereby increasing the specific surface area of electrodes, increasing the power output per unit volume/mass, facilitating sealing at high temperatures, and decreasing costs. The electrolyte in the hollow fibre configuration will be fabricated firstly by a combined phase inversion/sintering technique and consists of a thin dense layer, with integrated porous sub-layers on both sides. The porous sub-layers will then be deposited with anode and cathode materials, to produce a single hollow fibre SOFC, bundles of which will be assembled subsequently into a SOFC stack. The performance of both single cells and SOFC stacks will be investigated as a function of the fabrication and operational parameters. Initially, yttrium-stabilised zirconia (YSZ) will be used as the electrolyte, as the feasibility of producing this in fibre form has already been established, though not yet at the targeted electrolyte thickness of < 10 micron and with the required structure; to decrease operating temperatures from ca. 900 to 500-750 C, Ce0.9Gd0.1O1.95 (CGO) electrolyte will be used subsequently. As this proposal is concerned with establishing feasibility of the reactor design concept, hydrogen will be used as a model fuel at Ni anodes, coupled to oxygen reduction at La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) cathodes; reactor performance with other fuels would be part of a subsequent project proposal.

氧化物燃料电池（SOFC）以高（高达80％）化学至电/热转化效率而闻名，其在燃料摄入量（氢，天然气，甲醇和其他石油产品等）中的多功能性及其相对环境上的良性运行，具有很高的市场潜力，但尚未确定良好的技术和经济性，这些问题是良好的技术和经济性，这些问题和经济性涉及这些问题，并且这些问题是这些问题，并且这些问题是这些问题，并且这些问题是这些问题，并且这些问题是这些问题，并且是质量的，并且是在这些范围内，并且涉及这些问题，并且是质量的。开发了一种新颖的SOFC设计，使用空心纤维制造，从而增加了电极的特定表面积，增加了单位体积/质量的功率输出，在高温下促进密封并降低了成本。空心纤维构型中的电解质将首先通过相位反转/烧结技术制成，并由薄的密集层组成，两侧都有积分的多孔子层。然后，多孔的子层将用阳极和阴极材料沉积，以产生单个空心纤维SOFC，其束将随后组装到SOFC堆栈中。单细胞和SOFC堆栈的性能将作为制造和操作参数的函数进行研究。最初，Yttrium稳定的锆石（YSZ）将用作电解质，因为已经建立了以纤维形式产生这种情况的可行性，尽管尚未在靶向电解质厚度<10微米的靶向电解质厚度下，并且具有所需的结构。降低CA的工作温度。 900至500-750 C，CE0.9GD0.1O1.95（CGO）将使用电解质。由于该提案与建立反应堆设计概念的可行性有关，因此氢将用作Ni阳极的模型燃料，并在LA0.6SR0.4CO0.2FE0.8O3（LSCF）阴极的LA0.6SR0.4CO0.4CO0.2FE0.8O3（LSCF）阴极中耦合；与其他燃料的反应堆性能将成为随后的项目建议的一部分。
