Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
In a method of reacting an organic reactant at an electrode of an anode-cathode electrode pair to form an organic product, comprising contacting one member of the electrode pair with the organic reactant and externally imposing an electrical potential across the electrode pair, the improvement wherein said organic reactant is gaseous, and both electrodes of said electrode pair are in contact with solid polymer electrolyte means therebetween or with a porous non-electrode layer bonded to a surface of the solid polymer electrolyte.
Claim 2
Dependent Claim
82 words
In a method of reacting an organic reactant at an electrode of an anode-cathode electrode pair to form an organic product, comprising contacting one member of the electrode pair with the organic reactant and externally imposing an electrical potential across the electrode pair, the improvement wherein said organic reactant is gaseous, and both electrodes of said electrode pair are in contact with solid polymer electrolyte means therebetween or with a porous non-electrode layer bonded to a surface of the solid polymer electrolyte.
Claim 3
Dependent Claim
73 words
In a method of endothermically reacting an organic reagent at an electrode of an electrode pair within an electrolytic cell to form an organic product, which method comprising externally imposing an electrical potential across said electrode pair, the improvement wherein said electrode pair are both in contact with a solid polymer electrolyte or with a porous, non-electrode layer bonded to a surface of the solid polymer electrolyte, and said organic reagent is gaseous.
Claim 4
Dependent Claim
73 words
In a method of endothermically reacting an organic reagent at an electrode of an electrode pair within an electrolytic cell to form an organic product, which method comprising externally imposing an electrical potential across said electrode pair, the improvement wherein said electrode pair are both in contact with a solid polymer electrolyte or with a porous, non-electrode layer bonded to a surface of the solid polymer electrolyte, and said organic reagent is gaseous.
Claim 5
Dependent Claim
