Solid oxide fuel cell stack: Temperature regulation

Abstract

A fuel cell produces electricity and heat [1,2]. Low thermal conductivity of materials composed a solid oxide fuel cell (SOFC) and absence of effective heat carriers can lead to significant temperature irregularity within the SOFC stack. A heat model of a SOFC system included a stack consisted of tubular cells, a reactor for methane partial oxidation (R-MPO), and an afterburner has been developed. The results of simulation were proved using the SOFC system on the base of 16-cell stack.
