Barrier Layer Slurry


Product Overview

This product is an SOFC barrier layer slurry specially optimized for YSZ electrolyte systems. Its core component is GDC.
As a key material for SOFCs, the slurry can be applied by screen printing, spraying, and other coating techniques to form a dense thin film between the LSCF cathode and YSZ electrolyte. This barrier layer effectively prevents elemental diffusion and interfacial reactions between the cathode and electrolyte.
