An Improved Internal Reforming Solid Oxide Fuel Cell and a Process for Fabrication Thereof

Solid oxide fuel cell, single cell is capable of reducing the carbon deposition to the extent of 50 to 75% and consuming the remaining carbon during operation, thereby increasing the life span of fuel cell.

• The internal reforming SOFC of the present invention utilizes the hydrocarbon fuel directly.
• The present invention discloses anode compositions having reduced carburization rate thereby enhancing the working life of product.
• SOFC of the present invention is capable of operating ≥ 800^oC to enable the reforming of fuel.
• Present invention provides a simple, cost-effective and industrially scalable process for fabricating internal reforming anode supported SOFC.
• Present invention eliminates tedious leaching and infiltration steps as reported in prior-art.
