High temperature oxidation of AISI 441 in simulated solid oxide fuel cell anode side conditions
Journal article, 2022
This study investigates the corrosion of AISI 441 in simulated anode conditions of solid oxide fuel cells (SOFCs). Several parameters such as temperature, humidity, surface condition, pre-oxidation temperature and environment, were investigated. Samples pre-oxidized at 800 ºC were protective at 550–900 ºC, while as-received samples showed protective behavior only at 900 ºC. Additional exposures performed at 600 ºC revealed the negative effect of increasing steam concentration, the beneficial effect of grinding, while pre-oxidation at 600 ºC did not improve the protectiveness. The role and the interplay of the aforementioned factors are discussed.
