Description
本願発明の発明者らは、従来の電解質−アノード積層体について鋭意研究し、イオン伝導性能の低下原因について、以下の知見を得るに到った。
本願発明は、固体電解質層と、この固体電解質層に積層されたアノード層とを備えて構成される燃料電池用複合材料であって、上記固体電解質層は、ペロブスカイト構造のAサイトが、バリウム(Ba)とストロンチウム(Sr)の少なくとも一方からなるとともに、Bサイトの四価の陽イオンの一部を三価の稀土類元素で置換したイオン伝導体から構成されており、上記アノード層は、上記固体電解質層と同一組成の電解質成分と、ニッケル(Ni)触媒とを含んで構成されているとともに、少なくとも固体電解質層との境界部分に稀土類元素を含む添加物を含んで構成されるものである。
以下、本願発明の実施形態を図に基づいて説明する。
従来の電解質−アノード積層体において、固体電解質層におけるNi成分が相当量拡散する原因と、本発明の作用機構について、速度論的観点及び熱力学的観点から考察した。
