Introduction to Separator for SOFC Stack
Solid Oxide Fuel Cell (SOFC) stacks are a key component in high - efficiency energy conversion systems. The separator in an SOFC stack plays a crucial role. It serves as a physical barrier between individual cells in the stack, preventing gas mixing while allowing for the efficient transfer of electrons. A high - quality separator should have excellent electrical conductivity, good chemical stability in the harsh SOFC operating environment (high temperatures and reactive gases), and sufficient mechanical strength to withstand the stresses during operation and assembly. The performance of the separator directly impacts the overall efficiency, durability, and reliability of the SOFC stack.
