General description

LSM-20 is a state of art electrode material for solid oxide fuel cells (SOFCs). LSM-20 possesses both ionic and electronic conductivity and belongs to the ABO3 perovskite oxide family.


Lanthanum strontium manganite (LSM-20/GDC 10) is a ferromagnetic material, a Sr-doped LaMnO3 that is mainly used as a cathode material for solid oxide fuel cells (SOFCs). It also acts as a magnetic fluid, which can further be used as an inducer of tumor hyperthermia.

  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.
