In the last decades, mainly due to the advent of new technologies, with the exponential growth of the population, the intensification of the use of fossil fuels has generated great impacts to the environment. In this scenario, the search for energy alternatives has been constant. A rising solution is the use of the fuel cell technology, which has the principle of converting chemical energy into electrical energy. This work aimed to study calcium cobaltite as a potential cathode material for solid oxide fuel cells (SOFC). Powders of composition Ca3CuxCo4-xO9-d (0 = x = 0.15) were obtained using the Pechini method modified by using gelatin. The obtained powders were calcined at 900 °C for 2 h and characterized by X-ray diffractometry (XRD) an...
