Resumo
The development of solid oxide fuel cells operating at intermediate temperature (IT-SOFCs) and using
carbonaceous fuels to generate power have been crucial for the widespread commercialization of
SOFCs. Gadolinium-doped cerium oxide (CGO) is known to display the desired properties to be used
both as a high ionic conductor electrolyte at intermediate temperatures and as an active layer in the
anode due to its catalytic properties for the decomposition of fuels containing hydrocarbons. In this
study IT-SOFCs were fabricated with highly reactive nanorods of CGO electrolyte powder with shape
controlled by a hydrothermal synthesis developed in this project. The tested fuel cell system consists
of the CGO electrolyte support, lanthanum strontium cobalt ferrite (LSCF) cathode and Ni/CGO anode.
The performance of the cell was evaluated with hydrogen as a fuel and air as an oxidant at
temperatures between 500–700 °C, further work will be carried out to evaluated the performance of
the cell when operating with natural gas. The experimental results indicate that a high-performance
IT-SOFC can be obtained with a relatively low temperature (1.150 C) two-step sintering of the ceriabased
layers.
