This paper presents a performance test of a 110 cm(2) molten carbonate fuel cell bench cell as a function of output current and gas utilization. These results are compared with the predictions of cell performance of two analytical models, the simple and extended model, for which a revised derivation is given. A comparison of measurements and models results in a value for the quasi-ohmic resistance, r, of 1.02 and 1.07 Omega cm(2). respectively, for the simple model and the extended model. Using this as the only fitted parameter and other theoretical parameters, the simple and the extended model describe the cell performance with a relative error of at most 5 and 1%, respectively, for fuel utilization above 10%. Both models have therefore shown their reliability.
