Abstract

This paper aims to design a lumped-capacity model
of a reversible solid oxide cell stack for hydrogen electrolysis.
The lumped-capacity model needs to have an adequate representation
of the electrical dynamics over a wide operating
range and a model structure suitable for the design of a physical
emulator. The grey-box model is based on data obtained by electrochemical
impedance spectroscopy conducted on a commercial
solid oxide cell stack for four different gas compositions at six
aging stages. In addition, a comparison of the experimental and
simulated voltage response of the reversible solid oxide cell stack
in cyclic reversible operation mode was conducted at different
aging levels of the stack.
