Special Issue Information

Dear Colleagues,

Solid oxide fuel cells are a unique kind of energy conversion device that can convert chemical energy from fuel to electrical energy with high efficiency and almost zero pollution emissions at relatively high operating temperatures. Recently, it has attracted tremendous momentum due to the overwhelming superiorities of all-solid-state structure and practical fuel flexibility. Not only can gaseous fuels such as hydrogen, natural gas/methane, carbon monoxide, or propane and butane be fed into the anode fuel chamber for SOFC, but liquid fuels such as ethanol, octane, and even solid carbon fuels also can. Nevertheless, such a promising technology has not been applied practically or commercialized owing to its high manufacturing costs, durability, and robustness of the materials, including electrodes, electrolytes, and interconnects. In addition, theoretical studies including multiscale modeling, simulation, and in situ characterization are also necessary to achieve a rational design of materials and structures of SOFCs with unique functionalities for efficient energy conversion and storage.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Abstract
LaBaCo2−xMoxO5+δ (LBCMx, x = 0–0.08) cathodes synthesized by a sol-gel method were evaluated for intermediate-temperature solid oxide fuel cells. The limit of the solid solubility of Mo in LBCMx was lower than 0.08. [...] Read more.
LaBaCo2−xMoxO5+δ (LBCMx, x = 0–0.08) cathodes synthesized by a sol-gel method were evaluated for intermediate-temperature solid oxide fuel cells. The limit of the solid solubility of Mo in LBCMx was lower than 0.08. As the content of Mo increased gradually from 0 to 0.06, the thermal expansion coefficient decreased from 20.87 × 10−6 K−1 to 18.47 × 10−6 K−1. The introduction of Mo could increase the conductivity of LBCMx, which varied from 464 S cm−1 to 621 S cm−1 at 800 °C. The polarization resistance of the optimal cathode LBCM0.04 in air at 800 °C was 0.036 Ω cm2, reduced by a factor of 1.67 when compared with the undoped Mo cathode. The corresponding maximum power density of a single cell based on a YSZ electrolyte improved from 165 mW cm−2 to 248 mW cm−2 at 800 °C. Full article
