Fuel cell system
Abstract
Abstract IN AN AIR-BREATHING FUEL CELL STACK, THE AIR SWEEP SIMULTANEOUSLY SUPPLIES OXIDANT AND MAINTAINS THE TEMPERATURE AND WATER BALANCE IN THE CELL. THE INDIVIDUAL CELLS OF THE STACK CONTAIN AN IMMOBILIZED STABLE ACID SYSTEM AS THE ELECTROLYTE. A BIPOLAR THERMALLY CONDUCTIVE PLATE HAVING A COOLING FIN ON ONE SIDE IS DISPOSED BETWEEN AND IN CONTACT WITH ELECTRODES OF ADJACENT CELLS. GAS FLOW CHANNELS ON EACH OF THE ELETRODE-CONTACTING SURFACES OF THE PLATES INTERCOMMUNICATE ON THE ACTIVE AREA OF THE ELECTRODES FRO DISTRIBUTION OF THE FUEL AND AIR OVER THE ELECTRODES. IN A COMPACT SYSTEM, EXPECIALLY ADAPTED FOR USE IN REMOTE AREAS, THE FUEL CELL ASSEMBLY IS USED IN COMBINATION WITH A HYDROGEN GENERATOR.
