Abstract

Solid oxide cell stacks can be operated in fuel cell and electrolysis modes according to the electricity demand. Dynamic characteristics of the stack in an adiabatic environment undergoing mode step-switching was presented and analyzed in this paper. Stack temperature and its variation rate, and stack voltage and power output are illustrated. The round trip efficiency of the stack during a switching transient process was calculated and compared when adopting different operational turns. For switching modes, round trip efficiencies of two different processes are 87.4% and 84.6%, respectively.
