Fuel cell construction
Abstract
Abstract THIS INVENTION PERTAINS TO A FUEL CELL WHICH COMPRISES A CASE WITH POROUS POSITIVE AND NEGATIVE ELECTRODES INSERTED THEREIN DIVIDING THE INTERIOR OF THE CASE INTO THREE SECTIONS. ELECTROLYTE FILLS THE INNER SECTION OR SPACE. MEANS FOR INTRODUCING AN OXIDIZING GAS INTO THE SPACE BEHIND ONE POROUS ELECTRODE AND A FUEL BEHIND THE OTHER ARE PROVIDED. THE INNER SECTION IS DIVIDED BY A POROUS MEMBRANE SUBSTANTIALLY PARALLEL TO THE ELECTRODES COMPRISING SYNTHETIC FIBERS PREPARED FROM RESIN CONDENSATION PRODUCTS OF PHENOLS AND ALDEHYDES WHICH CAN BE FIBERIZED AND CURED. THIS MEMBRANE PERMITS COMMUNICATION OF ELECTROLYTE BETWEEN ELECTRODES BUT PREVENTS PASSAGE OF SMALL BUBBLES OF OXIDIZING OR FUEL GASES.
