Introduction to Separator for SOFC Stack
Solid Oxide Fuel Cell (SOFC) stacks are a highly efficient and environmentally friendly energy conversion technology. The separator in an SOFC stack plays a crucial role. It serves to electrically connect individual cells in the stack in series or parallel, isolates the fuel and oxidant gases to prevent cross - leakage, and provides mechanical support for the stack structure. A high - quality separator must have excellent electrical conductivity, chemical stability in the harsh SOFC operating environment (high temperatures, oxidizing and reducing atmospheres), good thermal expansion matching with other components of the stack, and sufficient mechanical strength.
