Abstract

Effects of ripple-current dynamics and load transients on the performance and reliability of solid-oxide fuel cell (SOFC) is investigated in this paper. A brief description of the proposed system-modeling and simulation methodologies is presented. The effect of harmonics in the current, drawn from the SOFC by a power electronics subsystem (PES), on the temperature, and fuel utilization of the SOFC is studied. Impacts of modulation strategies on the transient response, flow parameters and current density are studied. The impact of the magnitude of SOFC output current and microcrack density and material degradation is demonstrated.
