Abstract

In this paper an internal reforming SOFC is simulated, including the Balance-of-Plant (BoP) it is embedded in. Various approaches are evaluated to provide data for the trade-off between system efficiency and fuel cell health. The results reveal that controlled single-pass fuel utilisation (~50%) with a maximised system fuel utilisation of 85% is feasible. The operating voltage, current trajectories and detailed patterns of voltage losses and efficiencies are captured. The anode activation loss is observed to be the key contributor to the operating voltage variation when anode-off gas recycling is applied to improve the system’s Uf. The BoP modifications are presented to identify the optimal recycling point in the process flowsheet. The simulation results showed that in a comprehensive BoP, optimisation of system fuel utilisation and efficiency through tunning of the anode-off gas recycle needs exploring of both flowsheet and operating parameters enhancement.
