Description
Summary:The EOS Project carries on an industrial research on Stationary Fuel Cells based on the SOFC technology developed by Siemens, through a co-operation between TurboCare S.p.A. and Politecnico di Torino. This paper describes testing of the 5kW Alpha 6 SOFC with a low heating value fuel. A factorial analysis has been applied considering three factors: methane percentage, stack temperature and current. The obtained data have been analyzed using the Analysis of Variance (ANOVA) for every dependent variable and a non-linear regression model for the voltage. Those models were used to evaluate the performance of the system. The analysis has focused on how fuel dilution affects the local fuel utilization in different sectors of the stack.
