NOVELTY - Liquid electrolyte fuel cell system (10) comprises: at least one fuel cell, each fuel cell comprising a liquid electrolyte chamber between opposed electrodes, and means (30, 32) e.g. for supplying a gas stream to a gas chamber adjacent to the electrode; a liquid electrolyte storage tank (40); means to circulate liquid electrolyte between the liquid electrolyte storage tank and each liquid electrolyte chamber; a water storage tank (60); and means for condensing water vapor from the spent gas stream, and for feeding the condensed water vapor into the water storage tank.    USE - Used as liquid electrolyte fuel cell system.    ADVANTAGE - The liquid electrolyte fuel cell system: is capable of maintaining constant volume of electrolyte; prevents back-diffusion of electrolyte during operation; and utilizes the baffles, which suppress any turbulence from the in-flowing water.    DETAILED DESCRIPTION - Liquid electrolyte fuel cell system (10) comprises: at least one fuel cell, each fuel cell comprising a liquid electrolyte chamber between opposed electrodes, and means (30, 32) for supplying a gas stream to a gas chamber adjacent to the electrode and withdrawing a spent gas stream (38) from the gas chamber adjacent to the electrode, where the electrodes are an anode and a cathode; a liquid electrolyte storage tank (40); means to circulate liquid electrolyte between the liquid electrolyte storage tank and each liquid electrolyte chamber; a water storage tank (60) adjacent to the liquid electrolyte storage tank; and means for condensing water vapor from the spent gas stream, and for feeding the condensed water vapor into the water storage tank, where the water storage tank has an overflow outlet, and a duct that provides communication between the liquid electrolyte storage tank and the water storage tank below the level of the overflow outlet.
