Abstract
FUEL CELLS OFFER THE PROMISE OF HIGHLY EFFICIENT CONVERSION OF FUEL TO ELECTRICITY. A KEY PROBLEM IN THE SUCCESS OF PHOSPHORIC ACID FUEL CELLS IS THE OXIDATIVE CORROSION OF CATALYZED AIR CATHODE CARBONS. IN PHASE I, THE USE OF CORROSION STABLE, SPECIFICALLY FLUORINATED CARBONS WILL BE EVALUATED AS POTENTIAL CATALYST SUPPORTS. THESE WILL BE CHARACTERIZED, FABRICATED INTO AIR CATHODES, AND TESTED IN CONCENTRATED PHOSPHORIC ACID SOLUTION AT ABOUT 200EC. IMPROVEMENTS IN CORROSION STABILITY OVER UNTREATED CARBONS WILL BE DETERMINED. PHASE II STUDIES WILL INVOLVE OPTIMIZATION OF FLUORINE CONTENT AND GRAPHITIZATION LEVEL IN THE CARBONS TO PROVIDE FURTHER IMPROVEMENTS IN CORROSION RESISTANCE.
