Fuel cell gas manifold system
Abstract
Abstract A MANIFOLD SYSTEM FOR DISTRIBUTING THE FLOW OF REACTANT GASES THROUGH A FUEL CELL TO PREVENT A DRYING OUT OF THE CELL. THE FUEL CELL INCLUDES A FUEL ELECTRODE, AN OXIDANT ELECTRODE, AND AN AQUEOUS ELECTROLYTE RETENTIVE MATRIX LOCATED BETWEEN THE ELECTRODES. THE MANIFOLD SYSTEM INCLUDES A GAS CHAMBER FOR DISTRIBUTING THE FLOW OF AT LEAST ONE OF THE REACTANT GASES OVER THE SURFACE OF ITS ELECTRODE IN A CIRCUITOUS PATH BETWEEN THE INLET AND OUTLET OF THE CHAMBER. THE INLET AND OUTLET ENDS OF THE CHAMBER ARE LOCATED CLOSELY ADJACENT TO EACH OTHER WITH RESPECT TO THE PATH FOLLOWED BY THE GAS FLOWING THROUGH THE CHAMBER SO THAT THE DRIEST AND WETTEST REGIONS OF THE CELL NEAR THE INLET AND OUTLET ENDS, RESPECTIVELY, OF THE CHAMBER ARE CLOSE TOGETHER TO PREVENT A DRYING-OUT OF THE CELL.
