A comparative analysis of the features of the formation, morphology, and electrochemical activity of composite anodes of solid oxide fuel cells was performed using nanosized particles of NiO and Ce_0.8Gd_0.2O_2 – δ. The direct introduction of NiO nanoparticles into cermet composition leads to technological problems during screen printing of electrode layers associated with the oxidation of organic components of electrode pastes with oxygen, which is desorbed from the NiO surface. Such problems can be solved by pre-heating treatment of NiO. However, this treatment and subsequent firing of the anodes leads to an increase in the particle size to submicron. An increase in electrochemical activity can be achieved by impregnating the anodes with the formation of nanosized catalytically active particles on their surface.

使用纳米尺寸的NiO和Ce _0.8 Gd _0.2 O _2-δ颗粒对固体氧化物燃料电池复合阳极的形成，形态和电化学活性进行了比较分析。。将NiO纳米颗粒直接引入金属陶瓷组合物中会导致在丝网印刷电极层时出现技术问题，这些问题与电极浆料的有机成分被氧氧化有关，氧从NiO表面脱附。这些问题可以通过对NiO进行预热处理来解决。然而，阳极的这种处理和随后的焙烧导致粒径增加至亚微米。通过浸渍阳极并在其表面上形成纳米级催化活性颗粒，可以实现电化学活性的提高。
