Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
IN A METHOD OF OPERATING A FUEL CELL HAVING AN ANODE ELECTRODE AND A CATHODE ELECTRODE WITH AN ELECTROLYTE COMPARTMENT THEREBETWEEN, THE IMPROVEMENT WHICH COMPRISES FORMING SAID ANODE ELECTRODE COMPRISING AN ELECTRON-CONDUCTIVE SUPPORT, A CATALYST, AND A STABLE INACTIVE NUCLIDE DISTRIBUTED THEREIN AND THERETHROUGH IN DISCRETE SUBDIVIDED FORM, SAID NUCLIDE BEING CHARACTERIZED BY YIELDING, UPON ACTIVATION IN A THERMAL NEUTRON FLUX, A RADIONUCLIDE, SUBJECTING SAID ANODE TO SAID NEUTRON FLUX TO ACTIVATE THE NUCLIDE TO PRODUCE SAID RADIONUCLIDE, THEN REMOVING THE ACTIVATED ANODE FROM SAID FLUX AND USING THE SAME IN A FUEL CELL, INTRODUCING FUEL TO THE ANODE, SAID RADIONUCLIDE ACTING TO IRRADIATE SAID ANODE TO DEPOSIT ENERGY THEREIN, AND SAID ANODE TRANSFERRING SAID ENERGY TO FUEL ANODE-ELECTROLYTE INTERFACES THEREIN TO ACTIVATE FUEL REACTIONS, AND ELECTROCHEMICALLY OXIDIZING THE FUEL AT SAID ANODE BY THE AID OF SAID RADIATION TO GENERATE A CURRENT.

Claim 3
Dependent Claim
54 words
IN A FUEL CELL HAVING AN ANODE ELECTRODE AND A CATHODE ELECTRODE WITH AN ELECTROLYTE COMPARTMENT THEREBETWEEN, THE IMPROVEMENT WHEREIN SAID ANODE ELECTRODE COMPRISES AS AN INTERMEDIATE FUEL REACTION ACTIVATING AGENT A STABLE NUCLIDE DISTRIBUTED THROUGH SAID ANODE ELECTRODE, SAID NUCLIDE BEING SELECTED FROM THE CLASS CONSISTING OF THULIUM-169, LUTETIUM-176, RHENIUM-185 AND NATURAL THALLIUM.
