TL;DR: A mixed ion conductor is reported on that allows rapid transport of both protons and oxide ion vacancies at relatively low temperatures and appears linked to the mixed conductor’s enhanced catalytic activity for sulfur oxidation and hydrocarbon cracking and reforming, as well as enhanced water adsorption capability.

TL;DR: The much-improved capacity, rate capability, and cycling stability may be attributed to the unique hierarchical network structures, which improves electron/ion transport, enhances the kinetics of redox reactions, and facilitates facile stress relaxation during cycling.

TL;DR: In this article, the authors developed a new composition of oxide proton conductor, Ba(Zr0.1Ce0.7Y0.2) O3 d (BZCY7), which exhibits not only adequate proton conductivity but also sufficient chemical and thermal stability over a wide range of conditions relevant to SOFC operation.

TL;DR: In this article, a new anode with nanostructured barium oxide/nickel (BaO/Ni) interfaces for low-cost solid oxide fuel cells (SOFCs) was proposed.

TL;DR: In this paper, a test cell platform with a new electrode structure is utilized to determine the intrinsic surface catalytic properties of an electrode. And the authors demonstrate that an efficient electrode architecture has been demonstrated that can make effective use of desirable properties of two different materials: fast ionic and electronic transport in the backbone (LSCF) and facile surface kinetics on the thin-film coating (LSM), suggesting that the enhanced electrocatalytic activity of LSM-coated LSCF is attributed possibly to surface activation under cathodic polarization.
