About Lanthanum Strontium Manganite Cathode Ink (LSM20)

LanthanumStrontium Manganite Cathode Ink (LSM20)

Product Code: 6201635

The Lanthanum Strontium Manganite (LSM) Cathode Ink is made using a high-quality LSM powder to provide an excellent cathode ink. It can be used to fabricateyour own cells, and can be used to enhance contact of your solid oxide fuel cell to the test manifold.

Technical Specifications:

Formulation: (La_0.80Sr_0.20)_0.95MnO_3-x
Solids Loading: 62 - 72% by weight

 

Typical Use Guidelines:

This is a great inkfor making cathode catalyst layers for SOFC applications.
Stirring the ink before use is highly recommended. For best results, the inkshould be stirred with a spatula or a glass rod to achieve an even consistencyprior to use.

For making cathode catalyst layers that are well bonded to the electrolyte: The ink applied electrolyte istypically sintered at 100^oC (until it looks dry), then sintered at800C for 1 hr, and then at 1150^oC for 1 hr.  If an anode catalyst layer is also going to be applied (which would require a much higher sintering temperature than the this cathode), then it is recommended that the anodecatalyst layer to be bonded to the electrolyte first.  Exposing thiscathode ink to sintering temperatures much higher than 1150C would cause thedensification of the catalyst layer or decomposition of the phase and hence,low performance.  

For making electrical connections to a screen or wire: This ink istypically fired at 750C or 850C for 1 hour to ensure adhesion prior totesting at the desired test temperature. The adhesion obtained at lowersintering temperatures would not be as good as the adhesion obtained with thecatalyst layer that is sintered at much higher temperatures.
This ink can be used for screen printing for generating electrical connectionsfor wire attachments.

Precision Engineering for SOFC Cathodes

LSM20 Cathode Ink is engineered to provide superior electrochemical performance for SOFC systems. The formulation ensures high electronic conductivity and offers a stable thermal expansion coefficient, crucial for operational durability and compatibility with other cell components. Suitable for various cathode applications, it supports the production of efficient and long-lasting fuel cells.


Optimized for Screen Printing and Doctor Blade

This cathode ink comes as a ready-to-use paste with optimized viscosity, allowing seamless application via screen printing or doctor blade techniques. The fine particle size and homogeneous dispersion promote uniform coating, essential for achieving consistent results during cell fabrication.
