ABSTRACT:
Fuel cell comprising anolyte and catholyte compartments separated by a diffusion barrier and using sodium sulfide aqueous solution as anolyte and an aqueous catholyte solution. The apparatus is controlled to maintain a positive pressure differential across the anolyte/catholyte interface in the barrier towards the anolyte side to attenuate sulfide ion migration to the catholyte and reduce solid sulfur precipitation in the catholyte and thereby attenuate consequent cathode passivation or other forms of catholyte compartment poisoning.
