JFE Steel and CBMM partner to develop high-performance stainless steels for the energy sector
Solid Oxide Electrochemical Cells (SOC), including Solid Oxide Fuel Cells (SOFC) and its reverse Solid Oxide Electrolysis Cells (SOEC), have gained popularity on this scenario due to high efficiency and reduced GHG emissions for energy and hydrogen production.
Several projects for the implementation of these technologies have been initiated around the globe and many industrial plants are already operational, with capacities up to 80MW [1].
And even if recent advancement in the cell stacking design enabled the operating temperatures to decrease to lower ranges (700 – 850 °C), issues like creep deformation, oxidation performance and electrical conductivity are still important factors to ensure good efficiency of these systems.
JFE-FC1 is a Niobium (Nb) bearing stainless steel that does not require any coating for the application on the interconnectors of SOFC & SOEC, due to the formation of an unique oxide scale that will maintain the protective function of the components even without a coating.
In parallel, the addition of Nb increases creep resistance of the JFE-FC1 during the application, guaranteeing high temperature performance and mechanical stability of the stacks.
