    Abstract: Molten Carbonate Fuel Cell Integral Matrix Tape and Bubble Barrier A molten carbonate fuel cell matrix material is described made up of a matrix tape portion and a bubble barrier portion. The matrix tape portion comprises particles inert to molten carbonate electrolyte, ceramic particles and a polymeric binder, the matrix tape being flexible, pliable and having rubber-like compliance at room temperature. The bubble barrier is a solid material having fine porosity preferably being bonded to the matrix tape. In operation in a fuel cell, the polymer binder burns off leaving the matrix and bubble barrier providing superior sealing, stability and performance properties to the fuel cell stack. C-811

    Abstract: A fuel cell stack has external reactant gas manifolds pressed against its sides with seal material disposed between the sides of the stack and each manifold. The stack is disposed within a pressure vessel. An inert gas is fed into the pressure vessel at a pressure slightly above the pressure of the reactant gases within the stack. The inert gas continuously leaks into the reactant gas manifolds past the seal material, thereby preventing leakage out of the manifolds.

    Abstract: Molten Carbonate Fuel Cell Matrix Tape and Assembly Method A matrix material for a molten carbonate fuel cell is described which is flexible, pliable and has rubberlike compliance at room temperature. The matrix has three components comprising fine inert particulate material, larger crack attenuating ceramic particulate material, and an organic polymeric binder. A process of assembling a molten carbonate fuel cell utilizing the compliant matrix material is also described. The compliant matrix material is inserted into a molten carbonate fuel cell stack utilizing fuel cell anodes with sufficient porosity to contain excess electrolyte. The fuel cell is heated up to a temperature sufficient to remove the polymer binder and cause a portion of the electrolyte material present in the anode to wick into the matrix to substantially fill it completely.

    Abstract: FUEL CELL COOLING SYSTEM A cooler for removing waste heat from a stack of fuel cells includes a plurality of tubes for carrying the coolant through the stack. The tubes are disposed adjacent the nonelectrolyte side of electrodes in the stack in grooves or passageways formed in the surface of plates which separate one cell in the stack from another. Since the tubes are exposed to the electrolyte used in the stack they must be made from or at least include a protective coating of material which is stable in the electrolyte. Preferably this material is also a dielectric to prevent shunt currents from passing into the tubes and coolant which may be water.

    Abstract: METHOD FOR FEEDING REACTANT GAS TO FUEL CELLS IN A STACK AND APPARATUS THEREFOR A flow scheme for feeding a reactant gas to the cells of a fuel cell stack wherein the cells are connected electrically in series. For example, the fuel gas is passed in parallel over a portion of each fuel electrode and thereupon into a mixing manifold which directs the exhausted gases in parallel over a different portion of each fuel electrode and thereupon into another manifold. This is continued, depending upon the stack configuration, with the exhausted gases passing back and forth in parallel over different portions of the fuel electrodes and exhausting into a manifold until the fuel gas has covered the entire fuel electrode of each cell in the stack. This reduces the harmful effect of a blockage within the reactant gas chamber of a cell and also reduces the harmful effect caused by a maldistribution of current in one of the cells in the stack.
