Single intermedium-temperature SOFC prepared by glycine–nitrate process

Composite cathode La0.6Sr0.4Co0.2Fe0.8O3–Sm0.1Ce0.9O1.95–Ag for intermediate-temperature solid oxide fuel cells

“…5) shows that the maximum power density of the SOFC with LSCF-SDC cathode is 124.6 mW/cm 2 . This value is higher than that in our previous work [10], but lower than the SOFC with LSCF-SDC-Ag which gives a value of 173.8 mW/cm 2 . This fact indicates the important role of Ag in improving the cathode performance of SOFCs.…”

A high performance solid oxide fuel cells operating at intermediate temperature with a modified interface between cathode and electrolyte

“…R interface = R total − R electrolyte ). 16 In this case, the interface resistance of the Cell-1 and the Cell-2 can be easily calculated as 0.05 and 0.3 cm 2 . Hereto, it can be seen that the intrinsical reason of the Cell-2 exhibiting a poor electrical performance lies in its bigger interface resistance.…”

Characterization of GdBaCo2O5+δ cathode for IT-SOFCs

“…For example, Ln 1−x Sr x CoO 3−δ [4][5][6][7][8][9], Ln 1−x Sr x Co 1−y Fe y O 3−δ (Ln represents lanthanide element, like La, Ce, Pr, Nd, Gd, etc.) [10][11][12][13][14][15] perovskite oxides, they have high electronic and ionic conductivity, as well as high catalytic activity for oxygen reduction reaction even at reduced temperature, and they have been known to exhibit higher cathodic performance than LSM. GdBaCo 2 O 5+δ (GBCO) has been studied in the structure and magnetotransport properties [16].…”
