Abstract

In this work, adding a NiTiO₃ (NTO) reforming layer is firstly adopted as a low cost method to improve the carbon tolerance in solid oxide fuel cells. XRD patterns suggest that NTO has a good chemical compatibility with the YSZ electrolyte, and NTO can be totally reduced to Ni and TiO₂ when exposing to the H₂ atmosphere. Maximum power densities for the cells with the NTO layers at 700 C are 270 mWcm^-2 with wet H₂ fuel, and 236 mWcm^-2 with wet methane fuel, respectively. Improved discharging stability for the cells with NTO layers has also been observed. The current density remains unchanged for the cells with NTO layers during a 26 h test, while it drops to zero within 1 h for the cells without NTO. Above electro-performance and long term stability tests suggest that fabricating a NTO reforming layer on the anode surface is an efficient and inexpensive method to realize highly carbon tolerant SOFCs. © 2014 Elsevier B.V.
