Impact of power-electronics systems on the performance and durability of tubular solid-oxide fuel cell

This paper analyzes the impacts of steady-state and transient electrical-feedback effects from the power-conditioning system (PCS) on the performance and durability of tubular solid-oxide fuel cells (TSOFCs). Subsequently, this paper explores the impacts of modulation/control strategies on the transient response, flow parameters and current density. This paper demonstrates how traditionally known superior modulation/control methodologies may have a negative effect on the TSOFC performance and lifetime unless carefully implemented. The interaction-analysis methodologies and the results presented in this paper lead to an improved understanding, and may yield realization of cost-effective, reliable and optimal power-electronics systems for TSOFC PCS.
