Abstract

The simultaneous gasification of coal and the generation of electrical current in a high-temperature solid electrolyte fuel cell of the form C, O2, fused metal/ZrO2(8 mol % Y2O3)/Pt, O2 with a fused metal anode is a promising new concept. This process utilizes part of the Gibbs energy change of the coal gasification reaction to generate electricity with the high thermodynamic efficiency characteristic of fuel cells. We present a lumped parameter model that describes the steady-state behavior of this novel fuel cell and discuss the effect of operating conditions upon cell performance. The electrochemical cell reactor is capable of producing very high current and power densities and exhibits steady-state multiplicity over a wide range of operating conditions.
