✦ Synopsis

One of the primary scientific aims within the solid oxide fuel cell (SPOFC) community is to lower the operating temperature of an SOFC system from about 800-1,000 °C to intermediate temperatures of about 600 °C [1]. The lower operating temperature decreases thermal stress in the materials and offers the use of cheaper materials. The cell unit itself benefits from a longer lifetime of the components, which is often limited by degradation of the functional layers caused by the enhanced diffusion in the materials at elevated temperatures [2-4]. To ensure a good performance in terms of conductivity,

Ni cermet anodes are commonly used in solid oxide fuel cells (SOFCs) [1][2][3][4], but there has been considerable interest in alternative oxide-based anodes [5]. The motivation for the alternative materials is to avoid problems with the Ni-based anodes, including susceptibility to coking in hydroca
