dc.description.abstractSolid oxide fuel cells (SOFCs) operating at high temperatures are highly efficient electrochemical devices since they convert the chemical energy of a fuel directly into heat and electrical energy. The electrochemical performance of an SOFC is significantly influenced by the materials and microstructure of the electrodes since the electrochemical reactions in SOFCs take place at three/triple phase boundaries (TPBs) within the electrodes. In this study, graphene in the form of reduced graphene oxide (rGO) is added to cathode functional layer (CFL) to improve the cell performance by utilizing the high electrical properties of graphene. Various cells are prepared by varying the rGO content in CFL slurry (1-5 wt %), the number of screen printing (1-3) and the cathode sintering temperature (900-1100 degrees C). The electrochemical behavior of the cells is evaluated by electrochemical performance and impedance tests. It is observed that there is a similar to 26% increase in the peak performance of the cell coated with single layer CFL having 1 wt % graphene and 1050 degrees C sintering temperature, compared to that of the reference cell.
