A perspective on low-temperature solid oxide fuel cells
TL;DR: In this article, the authors provide a perspective on solid oxide fuel cells operating at low temperature, defined here to be the range from ∼400 °C to 650 °C, with a focus on materials that have demonstrated good properties and cell performance.
Journal ArticleDOI
Enhancing SOFC cathode performance by surface modification through infiltration
TL;DR: In this article, the authors reviewed recent progress in enhancing SOFC cathode performance by surface modification through a solution-based infiltration process, focusing on two backbone architectures, inherently functional and skeletal, infiltrated using wet-chemistry processes.

Nano-socketed nickel particles with enhanced coking resistance grown in situ by redox exsolution
Dragos Neagu,Tae-Sik Oh,David Noel Miller,Hervé Ménard,Syed Munawer Bukhari,Stephen Richard Gamble,Raymond J. Gorte,John M. Vohs,John T. S. Irvine +8 more
TL;DR: It is shown that unlike nickel particles deposited on perovskite oxides, exsolved analogues are socketed into the parent perovkite, leading to enhanced stability and a significant decrease in the propensity for hydrocarbon coking, indicative of a stronger metal–oxide interface.

A high-performance cathode for the next generation of solid-oxide fuel cells
Zongping Shao,Sossina M. Haile +1 more
TL;DR: BSCF is presented as a new cathode material for reduced-temperature SOFC operation and demonstrated that BSCF is ideally suited to ‘single-chamber’ fuel-cell operation, where anode and cathode reactions take place within the same physical chamber.

Appraisal of Ce1−yGdyO2−y/2 electrolytes for IT-SOFC operation at 500°C
TL;DR: In this article, the authors evaluated thermodynamic and electrical conductivity data to select the most appropriate electrolyte composition for IT-SOFC operation at 500°C and found that the Gd 3+ ion is the preferred dopant, compared to Sm 3+ and Y 3+, at this temperature.
Journal ArticleDOI
Direct oxidation of hydrocarbons in a solid-oxide fuel cell
TL;DR: The observation that a solid-oxide fuel cell can be operated on dry hydrocarbons, including liquid fuels, without reforming, suggests that this type of fuel cell could provide an alternative to hydrogen-based fuel-cell technologies.
