Development of protective coatings for Solid Oxide Fuel Cell (SOFC) metallic interconnects for higher energy efficiency Share

Each cell of the Solid Oxide Fuel Cell (SOFC) is stacked or connected via interconnect widely made up of ferritic stainless steel.  As SOFCs are operated at high temperatures (500 to 800oC), the metallic interconnects must be protected. High chromium content of ferritic stainless steel leads to Cr poisoning which eventually impact the activity of electrodes and thereby worsening the cell performance. Hence, protective conductive ceramic coatings are used for SOFC metallic interconnects. This project is aimed to develop protective coatings for SOFC interconnect by the following steps:1. Optimization of process paratmeters to develop dense coatings, 2.Characterize the coatings at atomic scales using atom probe tomography.
