Method of forming paste-form fuel cell electrode

Claim 1

THE METHOD OF FORMING A FUEL CELL ELECTRODE UTILIZABLE FOR THE ELECTROCHEMICAL OXIDATION OF LIQUID FUEL WHICH COMPRISES THE STEPS OF: DISTRIBUTING TRANSITION METAL UPON POROUS ACTIVATED CARBON POWDER HAVING AN INITIAL SURFACE AREA OF FROM 50 TO ABOUT 1000 SQ. M./G. IN AN AMOUNT CONSTITUTING 0.1 TO 30 WT. PERCENT OF THE TOTAL METAL-CARBON COMPOSITION: FORMING THE METAL-CARBON COMPOSITION INTO A HOMOGENEOUS PASTE BY ADMIXTURE WITH A LIQUID ELECTROLYTE, SIMILAR TO AND COMPATIBLE WITH THE ELECTROLYTE WITH WHICH THE ELECTRODE IS TO BE EMPLOYED, SUPPLIED IN AN AMOUNT RANGING FROM THAT SUFFICIENT ONLY TO COMPLETELY WET THE SURFACE OF THE METAL-CARBON MIXTURE TO AN AMOUNT FORMING A SEMI-FLUID PORTION; SAID PASTE CONSTITUTING A CATALYTIC ELECTRODE PORTION; ASSOCIATING SAID CATALYTIC ELECTRODE PASTE WITH MEANS ADAPTED TO SUPPORT AND HOLD THE ELECTRODE PASTE IN ITS DESIRED SHAPE AND POSITION IN THE FUEL CELL, SAID SUPPORTING AND HOLDING MEANS BEING CAPABLE OF IONIC AND ELECTROLYTIC TRANSFER BETWEEN THE CATALYTIC PASTE MATERIAL AND THE FUEL CELL ELECTROLYTE; AND ASSOCIATING SAID PASTE WITH ELECTRONIC CONDUCTOR MEANS TO FORM THE ELECTRODE.

Claim 2

THE METHOD OF FORMING A FUEL CELL ELECTRODE UTILIZABLE FOR THE ELECTROCHEMICAL OXIDATION OF LIQUID FUEL WHICH COMPRISES THE STEPS OF: DISTRIBUTING TRANSITION METAL UPON POROUS ACTIVATED CARBON POWDER HAVING AN INITIAL SURFACE AREA OF FROM 50 TO ABOUT 1000 SQ. M./G. IN AN AMOUNT CONSTITUTING 0.1 TO 30 WT. PERCENT OF THE TOTAL METAL-CARBON COMPOSITION: FORMING THE METAL-CARBON COMPOSITION INTO A HOMOGENEOUS PASTE BY ADMIXTURE WITH A LIQUID ELECTROLYTE, SIMILAR TO AND COMPATIBLE WITH THE ELECTROLYTE WITH WHICH THE ELECTRODE IS TO BE EMPLOYED, SUPPLIED IN AN AMOUNT RANGING FROM THAT SUFFICIENT ONLY TO COMPLETELY WET THE SURFACE OF THE METAL-CARBON MIXTURE TO AN AMOUNT FORMING A SEMI-FLUID PORTION; SAID PASTE CONSTITUTING A CATALYTIC ELECTRODE PORTION; ASSOCIATING SAID CATALYTIC ELECTRODE PASTE WITH MEANS ADAPTED TO SUPPORT AND HOLD THE ELECTRODE PASTE IN ITS DESIRED SHAPE AND POSITION IN THE FUEL CELL, SAID SUPPORTING AND HOLDING MEANS BEING CAPABLE OF IONIC AND ELECTROLYTIC TRANSFER BETWEEN THE CATALYTIC PASTE MATERIAL AND THE FUEL CELL ELECTROLYTE; AND ASSOCIATING SAID PASTE WITH ELECTRONIC CONDUCTOR MEANS TO FORM THE ELECTRODE.
