Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
IN A FUEL CELL ELECTRODE STRUCTURE FOR THE ELECTROCHEMICAL OXIDATION OF A FUEL CONTAINING CARBON MONOXIDE WHEREIN THE ELECTRODE BODY CONTAINS CATALYST METAL AND BINDER MATERIAL HOLDING SAID ELECTRODE BODY TOGETHER IN A COHERENT, UNITARY, GAS PERMEABLE, ELECTRONICALLY CONDUCTIVE MASS ELECTRICALLY CONNECTED TO CURENT COLLECTING MEANS, THE IMPROVEMENT IN WHICH SAID ELECTRODE BODY IS RESISTANT TO POISONING BY CARBON MONOXIDE AND COMPRISES PLATINUM AND A CARBON MONOXIDE ANTI-POISONING ADJUVANT MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE OXIDES OF MOLYBDENUM AND THE OXIDES OF TUNGSTEN AND MIXTURES THEREOF SAID ADJUVANT MATERIAL BEING PRESENT IN THE PROPORTION OF AT LEAST 5 WEIGHT PERCENT OF THE TOTAL AMOUNT OF THE PLSYINUM SNF SFJUBSNY MSYRTISL PTRDRNY.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
90 words
IN A PROCESS OF GENERATING ELECTRICAL ENERGY UTILIZING A FUEL CONTAINING CARBON MONOXIDE, THE STEPS COMPRISING PROVIDING A FIRST ELECTRODE STRUCTURE HAVING A PLATINUM CATALYST CONTAINING AN ANTI-POISONING AGENT SELECTED FROM THE GROUP CONSISTING OF THE OXIDES OF MOLYBDENUM AND THE OXIDES OF TUNGSTEN AND MIXTURES THEREOF, PROVIDNING A SECOND ELECTRODE FOR THE REDUCTION OF AN OXIDANT, IONICALLY COMMUNICATING THE ELECTRODES, DELIVERING THE FUEL CONTAINING CARBON MONOXIDE TO THE FIRST ELECTRODE STRUCTURE, PERMITTING THE OXIDANT TO CONTACT THE SECOND ELECTRODE STRUCTURE, AND DRAWING AN ELECTRICAL CURRENT FROM THE ELECTRODE STRUCTURES.
