      abstract     = {Donor-substituted strontium titanates have been widely
                      recognised as alternative anode materials to the
                      state-of-the-art Ni/YSZ cermets in solid oxide fuel cells
                      (SOFCs). Electrolyte-supported SOFCs based on
                      Y0.07Sr0.895TiO3 ceramic anodes with different
                      microstructural designs were prepared. Ni or Ni with
                      Ce0.8Gd0.2O1.9 (CGO) was infiltrated onto the pore walls
                      within the ceramic anode framework as an electrocatalyst for
                      anode reactions. Performances and electrochemical impedance
                      spectroscopy measurements of the cells were analysed in
                      detail to observe the influence of low ionic conductivity of
                      Y0.07Sr0.895TiO3 to cell performance, to understand how to
                      control the degradation of the cells, and to obtain a
                      possible mechanism for the anode processes. The anode design
                      containing both functional and current collecting layers
                      with sufficient Ni-CGO infiltration is favourable for high
                      power output and low performance degradation.},
