General description

Lanthanum strontium cobalt ferrite (LSCF) is a mixed ionic and electron conducting pervoskite. The ionic conductivity is lower than YSZ although maintaining high conductivity. X-ray diffraction and electrochemical measurements of an operational LSCF cathode was conducted to study its lattice expansion during use. LSCF can be prepared by solid state reaction of individual cation oxides.
Lanthanum strontium cobalt ferrite (LSCF/GDC) belongs to the class of cathode materials that operate at low temperatures. It has mixed ionic and electronic conductivities with high electrocatalytic activity. It forms thin films with higher performance than the thick dense film.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Application

LSCF may be used as cathode in solid oxide fuel cells (SOFCs).
LSCF oxygen electrodes can be used in the fabrication of high-performance solid oxide fuel cells (SOFCs).

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.
