NbTi Ni O (NTNO) has been prepared using solid state synthesis and investigated as a potential anode material. The oxide form of NTNO has single phase rutile-type structure with tetragonal (P42/mnm) space group. The reduced form is a composite of nano-scaled particles of metallic Ni and Nb Ti O phase. Reduced NTNO showed high electronic conductivity up to 280 at 900 °C in reducing atmosphere, but suffers from low CTE equal to 3.78 10 K . Studies of NTNO as anode material were carried out in a three electrode - electrochemical half cell configuration under pure humidified H at 900 °C using a 2 mm thick zirconia electrolyte and without any additional current collector material. The r..
