Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
61 words
A gaseous fuel cell comprising a solid doped hydronium beta-alumina electrolyte which is positioned between and in direct electrical contact with a pair of gas permeable, electronically conductive electrodes, and means for supplying a hydrogen containing fuel gas containing water vapor to one of said electrodes and means for supplying an oxygen oxidant gas to the other end of said electrodes.
Claim 2
Dependent Claim
61 words
A gaseous fuel cell comprising a solid doped hydronium beta-alumina electrolyte which is positioned between and in direct electrical contact with a pair of gas permeable, electronically conductive electrodes, and means for supplying a hydrogen containing fuel gas containing water vapor to one of said electrodes and means for supplying an oxygen oxidant gas to the other end of said electrodes.
Claim 3
Dependent Claim
21 words
A gaseous fuel cell as in claim 1, in which the fuel gas is hydrogen and, the oxidant gas is oxygen.
Claim 4
Dependent Claim
78 words
A gaseous fuel cell comprising a fuel gas chamber separated from an oxidant chamber by a solid doped hydronium beta-alumina electrolyte, a gas permeable, electronically conductive electrode in contact with the fuel gas and electrolyte, another gas permeable, electronically conductive electrode in contact with the oxidant gas and electrolyte, a supply of a hydrogen containing fuel gas containing water vapor for the fuel gas chamber, and a supply of an oxygen oxidant gas for the oxidant gas chamber.
Claim 5
Dependent Claim
78 words
A gaseous fuel cell comprising a fuel gas chamber separated from an oxidant chamber by a solid doped hydronium beta-alumina electrolyte, a gas permeable, electronically conductive electrode in contact with the fuel gas and electrolyte, another gas permeable, electronically conductive electrode in contact with the oxidant gas and electrolyte, a supply of a hydrogen containing fuel gas containing water vapor for the fuel gas chamber, and a supply of an oxygen oxidant gas for the oxidant gas chamber.
Claim 6
Dependent Claim
21 words
A gaseous fuel cell as in claim 3, in which the fuel gas is hydrogen and, the oxidant gas is oxygen.
