Summary

Processing parameters for solid oxide fuel cell (SOFC) anode material were investigated in order to optimize the porosity of the component in order to develop a fuel cell with long term stability. Graphite vol. %, nickel oxide vol. %, compaction pressure and the sintering temperature were the four processing variables considered for the optimization technique. Two levels were considered for each variable. Using the factorial design of experiment technique, the experiments were performed. The different powders were mixed together and their particle size was made uniform by ball-milling technique. The mixed powder was pressed and sintered according to the design matrix. The volume and the weight of the sintered anode were measured in order to calculate the total porosity. Analysis of Variance (ANOVA) was performed on the porosity values. The results indicate that there is a higher level of interaction between the graphite, NiO and sintering temperature and the porosity.
