通过浸渍含纳米颗粒的铈基多孔支架（CGO），开发了一种用于制造具有改善的孔隙率和较低的烧结温度的固体氧化物燃料电池阳极的策略。CGO支架使用含有纳米颗粒和CGO和聚合物成孔剂的商业颗粒的丝网印刷油墨制造。扫描电子显微镜和原位超小角X-射线散射表明，掺入纳米粒子通过允许降低烧结温度来增加孔隙率。对称电池的电化学表征表明，在1000 ℃下烧结的电池与在1300 ℃下烧结的电池相比具有相似的电极极化。纽扣电池测试表明，降低烧结温度产生的电池在700 ℃及以下的氢气中表现更好，并且在使用合成气的所有温度下表现更好。这种方法有可能允许使用更广泛的纳米材料，对微观结构进行更精细的控制。
A strategy for fabrication of solid oxide fuel cell anodes with improved porosity and lower sintering temperatures by impregnation of nanoparticle-containing porous scaffolds of ceriagadolinia (CGO) has been developed. The CGO scaffolds are fabricated using a screen-printed ink containing nanoparticles and commercial particles of CGO and polymeric pore formers. Scanning electron microscopy and in situ ultra-small angle X-ray scattering show that incorporation of nanoparticles increases the porosity by allowing a reduction in sintering temperature. Electrochemical characterisation of symmetrical cells shows that the cells sintered at 1000 C possess similar electrode polarisation compared to those sintered at 1300 C. Button cell testing showed that reducing the sintering temperature produced cells which perform better at 700 C and below in hydrogen, and performed better at all temperatures using syngas. This approach has the potential to allow the use of a wider range of nanomaterials, giving a finer control over microstructure.
