Effect of Carburization on Hot Corrosion of Separator for Molten Carbonate Fuel Cell

Abstract

The corrosion damages of separators after 1754h operation has been studied, and the effect of Cr content and carburization on the corrosion has been discussed. The obtained results are as follows; 1) The separator materials are carburized. The carburization of separator is especially remarkable at the anode side. 2) The increase of Cr content improves the corrosion resistance in the anode side condition. 3) The carburization reduces the corrosion resistance and that effect is especially severe in the anode side condition.
