Abstract: An SOFC structure having segmentation of the mixed layer on a cathode electrode to allow a higher fraction of ionic phase in a mixed layer, resulting in improved microstructure that provides higher specific surface area for electrochemical reaction. This is accomplished by using a mixed ionic and electronic conductor (MIEC) layer (14) over the segmented layer (116) that supplies electrons laterally and vertically through the thickness of the mixed layer. Adequate connectivity between the cathode current collector (130) and electrolyte (20) for electrons is established, assuring efficient charge transfer and improved activity of the electrocatalyst in the porous cathode. Cell resistance is reduced and power output is improved. Further, the invention can efficiently incorporate a variety of functional layers on the anode electrode to improve protection from poisons and certain fuel mixtures that degrade cell performance, and can reduce stresses between fuel cell components while maintaining adequate connectivity with the anode current collector and electrolyte via an Ni-YSZ anode.

Abstract translation: SOFC结构具有阴极电极上的混合层的分割，以允许混合层中较高的离子相分数，导致改善的微结构，为电化学反应提供较高的比表面积。 这通过在分层层（116）上使用混合的离子和电子导体（MIEC）层（14）来实现，该分层层（116）横向和垂直地提供电子束通过混合层的厚度。 建立了用于电子的阴极集电器（130）和电解质（20）之间的充分连接性，确保有效的电荷转移和改善多孔阴极中的电催化剂的活性。 电池电阻降低，功率输出得到改善。 此外，本发明可以在阳极电极上有效地并入各种功能层，以改善对毒素和某些燃料混合物的保护，降低电池性能，并且可以降低燃料电池组件之间的应力，同时保持与阳极集电器和电解液通过的充分连接 Ni-YSZ阳极。
