Flanges for the separator plate of molten carbonate fuel cells

摘要

The present invention refers to a particular composition of the removable flanges of the separator plate in molten carbonate fuel cells (MCFC), and to a method for production of the same, such as to provide optimal resistance to oxidisation and corrosion, and at the same time optimal electrical resistance. These properties are obtained via flanges made of stainless steel previously oxidised by means of a specific heat treatment in air.
