介绍 | Crofer® 22 APU* is a high-temperature ferritic stainless steel especially developed for application in solid oxide fuel cells (SOFC). At temperatures up to 900°C (1652°F) a chromium-manganese oxide layer is formed on the surface of Crofer® 22 APU which is thermodynamically very stable and possesses high electrical conductivity. The low coefficient of thermal expansion is matched to that of ceramics typically used for high-temperature fuel cells in the range from room temperature to 900°C (1652°F). Crofer® 22 APU is characterized by:
