Abstract:
A method and apparatus for continuous fabrication of homogeneous thin flake or powder electrolyte material from inorganic salt, metallic or similar materials or from mixtures of such materials for use in Carbonate Fuel Cell ("CFC") power plants. Electrolyte precursor powders are fed to a continuous blender type mixer using precision metering equipment that controls material feed rates. The homogenous mixture of blended powders is then fed into a high temperature melting tank in which the mixture is melted, forming the desired molten eutectic composition. The liquid eutectic melt drips from the melting tank through ceramic or metallic nozzles and to splat-cools on a rotating, water-cooled metal cylinder to produce uniform size, thin flake material. The thin flake electrolyte material can be used as-is, or it may be further processed using continuous grinding and powder fabrication equipment.

Abstract:
An integrated fuel cell and carbon capture system, operating on carbon- containing reactants including a liquid, wherein CO 2 in the fuel cell reacts or dissolves in the liquid; and a means for sequestering the reacted or dissolved CO 2 in the liquid by forming a stable carbonate compound and regenerating the liquid. The means for sequestering the reacted or dissolved CO 2 may be a source of group II metal ions, commonly found as finely divided waste mineral materials.
Abstract:
An aluminium electrode (102) for use in an aluminium-air fuel cell (101 ) is wedge-shaped, and has a disrupted surface (102a, 102b). The electrode may in particular have grooves (103) traversing from a top side to a bottom side. The grooves may be V-shaped with a width of from about 1 mm to about 12 mm and a depth of from about 1.5 mm to about 3 mm. The aluminium-air fuel cell comprising an aluminium anode (102) and an air cathode (104a, 104b) located in an electrolyte chamber. An inter- electrode gap between the aluminium anode and the adjacent air cathodes is from about 1 mm to about 2 mm. The electrolyte may include further comprises a seeding agent. A filter configured to remove suspended solids may be fluidly connected to the electrolyte chamber and a precipitator configured to precipitate hydrargyllite, said precipitator being fluidly connected to the electrolyte chamber. A battery of such cells is combined with a reserve power source (902) for providing power to a load while the aluminium-air fuel cells are inactive or starting up. A charging mechanism (912) configured to recharge the reserve power source using power supplied by the aluminium-air fuel cells when active.

The invention relates to a method for operating a fuel cell, particularly for operating a fuel cell in which the electrolyte responsible for proton conduction is volatile. Using the method according to the invention, such fuel cells can be better operated and exhibit an improved service life.
Abstract:
A method for controlling an amount of a liquid electrolyte in a polymer- electrolyte membrane of a fuel cell is provided. The method comprises enriching one or more of a fuel flow and an air flow with a vapor of the liquid electrolyte, the liquid electrolyte being unreplenishable via an electrochemical reaction of the fuel cell. The method further comprises delivering the vapor of the liquid electrolyte to the fuel cell including the polymer-electrolyte membrane via one or more of the gas-permeable anode and or the gas-permeable cathode. In this manner, loss of liquid electrolyte from the PEM membrane of the fuel cell can be reduced, leading to improved fuel- cell endurance.
