Molten carbonate fuel cells (MCFC) are being developed for large- scale power generation. One source of fuel is coal gasifiers, which presents the problem of coal gas contaminants and their effect on MCFC; HCl is the most serious and hence needs to be monitored. Different methods of detecting HCl in the gas phase were evaluated, and laser diode absorption is the most suitable. Temperature sensitivity and spectral interferences are discussed; it is shown that the P10 spectral line is the best. A diode for the P10 line is on order; experiments using the P5 line show the line to be unacceptable (overlap with CH{sub 4} line). Future planned work is outlined briefly. (DLC)
