A mathematical model is presented to describe the steady state behavior of high temperature solid electrolyte fuel cells. The resulting equations are solved for the case of anodic oxidation of hydrogen and carbon monoxide. Similar to chemical reactors, fuel cells are found to exhibit steady-state multiplicity over a wide range of parameters. The paper discusses the relative importance of the pertinent design and operating parameters in order to maintain ignited steady states corresponding to high current densities and nearly complete fuel conversion.
