The direct carbon solid oxide fuel cell with H sub(2) and H sub(2)O feeds

The performance of the direct carbon solid oxide fuel cell (C-SOFC) with a Ni/YSZ anode has been studied with a 50 mol% H sub(2),3 mol% H sub(2), and 7 mol% H sub(2)O feed at 750 [degrees]C. The electricity generation was dominated by consumption of H sub(2) fuel at 50 mol% H sub(2) and by carbon at 3 mol% H sub(2). The low (3 mol%) H sub(2) kept the Ni/YSZ anode in reduced state, enhancing its electrochemical oxidation activities. Introducing 7 mol% H sub(2)O initiated the water reaction with carbon to produce H sub(2) and CO that could serve as a fuel for further reactions in anode interlayer, exhibiting a decrease in the overall Faraday resistance of the C-SOFC.
