The purpose of this program extension was to test the scale-up characteristics a low-cost module concept and to increase power density to a level of 60 watts per square foot of cell area. Seven 36-cell modules, each having one square foot of cell area, but with some variations in cell structure, were constructed and tested. Two module configurations were used one had six rows of six cells each in electrical series, and the other had 18 pairs of cells in series. Tests of the six-cell modules generally produced 35 to 45 watts per square foot during the first few hundred hours of operation, but occasionally the output exceeded 60 watts per square foot. Such deviations were also observed in the cells of the larger modules described in this report. Some fabrication and operational problems associated with these larger modules were effectively overcome. Modifications were made in the plenums to improve the distribution of fuel. The maximum output obtained using hydrogen in these modules was 60.8 watts. Under otherwise like conditions but using a synthetic partial oxidation fuel, 48.6 watts output was attained. Author
