A Review of” Enhanced oxygen diffusion in low barium-containing La0.2175Pr0.2175Ba0.145Sr0.4Fe0.8Co0.2O3_ δ intermediate temperature solid oxide fuel cell cathodes”
Current solid oxide fuel cells (SOFCs) are still operating at high temperatures at between 800-1000 oC. These high-required temperatures are the main drawback for the commercialization of the device. Performance becomes an issue at these temperatures that means there is room for improvement. La0.2175Pr0.2175Ba0.145Sr0.4Fe0.8Co0.2O3_ δ(LPBSFC) has become a material of interest for use as cathode in SOFCs. This sparked interest can be attributed to the suspected good oxygen transport even at intermediate temperatures. In the paper being reviewed diffusion coefficient (D) and surface exchange coefficient (K) values measured for LPBSFC using time of flight secondary mass spectroscopy (ToF- SIMS) are compared to the D and K values measured for LPBSFC values measured for LPBCF using electrochemical impedance spectroscopy (EIS) done in a previous work.
A Review of “Surface-Related Effects Limiting the Performance of Solid Oxide Fuel Cell Cathodes”
This is a review of “Surface-Related Effects Limiting the Performance of Solid Oxide Fuel Cell Cathodes” by Edith Bucher (Lehrstuhl fur Physikalische Chemie, Montanuniversitat Leoben, Leoben, Osterreich BHM (2011) Vol. 156(11): 423 – 428.). The reviewed paper intended to investigate the possible reasons for the identified limited durability and optimum performance of Solid Oxide Fuel Cells (SOFC’S) and in particular the cathode. It is expected that external elements/compounds are responsible for the degradation of the cathode in a Solid Oxide Fuel Cell
