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.

固体氧化物燃料电池 (SOFC) 以其高（高达 80%）的化学到电/热转换效率、燃料摄入的多功能性（氢气、天然气、甲醇和其他石油产品等）以及相对环境友好而闻名。操作，具有很高的市场潜力，但由于突出的技术和经济问题尚未大规模生产。该拟议项目旨在通过建立使用中空纤维制造的 SOFC 的新颖设计的可行性和开发来解决这些问题,从而增加电极的比表面积，增加单位体积/质量的功率输出，有利于高温密封，降低成本。中空纤维结构的电解质将首先通过相转化/烧结组合技术制造，由薄致密层和两侧集成的多孔子层组成。然后，多孔子层将沉积有阳极和阴极材料，以生产单个中空纤维 SOFC，随后将其束组装成 SOFC 堆。单电池和 SOFC 堆的性能将作为制造和操作参数的函数进行研究。最初，钇稳定氧化锆 (YSZ) 将用作电解质，因为以纤维形式生产这种电解质的可行性已经确定，但尚未达到 < 10 微米的目标电解质厚度和所需的结构；将工作温度降低约。随后将使用900至500-750 C，Ce0.9Gd0.1O1.95（CGO）电解质。由于该提案涉及建立反应堆设计概念的可行性，因此氢气将用作 Ni 阳极的模型燃料，并与 La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) 阴极的氧还原相结合；反应堆使用其他燃料的性能将成为后续项目提案的一部分。
