Abstract
Molten carbonate type or phosphoric acid type fuel cells and a method for supplementing these fuel cells with an electrolyte are disclosed. A fuel cell having an extended life is provided by scattering a plurality of sealed supplementary electrolyte containers made of a material which is soluble in the electrolyte at elevated temperatures, and supplying the supplementary electrolyte from the dissolved containers to the fuel cell while the cell is working.
