OSTI ID:5559474
The present work was undertaken to investigate the vapor composition above alkali carbonate melts under fuel cell gas atmospheres. The technical results for this time period consist of preparing a design and constructing the apparatus required for the vapor phase molten carbonate studies. High temperature microwave spectroscopy is the technique which will be used for this work and the apparatus consists of three major components: a Hewlett Packard 8400C microwave spectrometer; a Cromemco Z-2D computer system; and a high temperature microwave absorption cell. The HP 8400C Microwave Spectrometer was installed in the laboratory and modified. A computer interface with associated hardware and software was developed to control a number of spectrometer parameters with the Cromemco Z-2D Computer. These include frequency sweep and measurement as well as data acquisition which permits signal averaging. Finally a high temperature microwave absorption cell had to be designed specifically for this project. The apparatus is undergoing performance tests and work is scheduled to begin on the alkali carbonate melts within this time period.
