Zusammenfassung:	A mathematical model of a tubular solid oxide fuel cell is presented. The complete electrochemical and thermal factors are accounted for in a rigorous manner. All required parameters are determined from independent sources; none is fit from performance data. To verify the accuracy of the model predictions, comparison is made with single cell test data. Agreement with electrochemical and thermal results are within 5%. Predictions are shown for power-voltage, irreversibilities, and temperature and current distributions under various conditions. 13 refs.
