A method for delivering a gas, comprising: providing a conduit which supplies natural gas to a geographic location; mixing a gas to be delivered with the natural gas for delivery to the geographic location; and providing a proton exchange membrane fuel cell at the geographic location, and wherein the gas which is distributed is hydrogen and which is consumed by the proton exchange membrane fuel cell to produce electricity. 3. A method for delivering a gas, comprising: providing a conduit which supplies natural gas to a geographic location; mixing a gas to be delivered with the natural gas for delivery to the geographic location; providing a proton exchange membrane fuel cell at the geographic location, and wherein the gas which is distributed is hydrogen and which is consumed as a fuel gas by the proton exchange membrane fuel cell; and providing a natural gas filtering assembly at the geographic location and which substantially prohibits the delivery of natural gas to the proton exchange membrane fuel cell at the geographic location. 4. A method as claimed in claim 3, and further comprising: providing an accumulator coupled in fluid flowing relation relative to the conduit at the geographic location, and which stores the gas delivered to the geographic location and which is mixed with the natural gas. 5. A method for delivering a gas, comprising: providing a conduit which supplies natural gas to a geographic location; and mixing a gas to be delivered with the natural gas for delivery to the geographic location; and wherein the conduit delivers a volume of natural gas, and wherein the gas which is mixed with the natural gas is hydrogen, and wherein the volume of the hydrogen is less than 50% of the volume of the natural gas. 6. A method for delivering a gas, comprising: providing a conduit which supplies natural gas to a geographic location; mixing a gas to be delivered with the natural gas for delivery to the geographic location; providing a fuel cell at a remote geographic location and which, during operation, consumes the gas which is mixed with the natural gas; providing a second miscible gas which is mixed with the source of natural gas; and providing a chemical reactor which is coupled in fluid flowing relation relative to the fuel cell and which is operable to convert the second miscible gas into a fuel gas which can be consumed by the fuel cell. 7. A method for delivering a gas to a geographic location, comprising: providing a source of natural gas; providing a conduit coupled in fluid flowing relation relative to the source of natural gas, and which delivers a volume of natural gas to the geographic location; providing a source of a gas to be delivered to the geographic location; mixing the source of the gas to be delivered with the natural gas for delivery at the geographic location; providing a first device at the geographic location, and which is coupled in fluid flowing relation relative to the conduit, and which consumes the natural gas delivered to the geographic location; and providing a second device at the geographic location, and which is coupled in fluid flowing relation relative to the conduit and which consumes the gas which is mixed with the natural gas, and which is delivered to the geographic location. 8. A method as claimed in claim 7, and wherein the conduit is coupled in fluid flowing relation relative to a natural gas network which services a wide geographic area.9. A method as claimed in claim 7, and wherein the s ource of the gas which is mixed with the natural gas has a volume of less than about 50% of the volume of the natural gas.10. A method as claimed in claim 7, and further comprising: providing an accumulator coupled in fluid flowing relation relative to the conduit, and which stores a volume of the gas which is delivered to the geographic location, and which is consumed by the second device. 11. A method as claimed in claim 7, and further comprising: providing a filtering assembly coupled in fluid flowing relation relative to the conduit, and which substantially prohibits the delivery of the natural gas to the second device. 12. A method as claimed in claim 7, and further comprising: providing an accumulator coupled in fluid flowing relation relative to the conduit, and which stores a volume of the gas which is delivered to the geographic location, and which is consumed by the second device; and providing a filtering assembly coupled in fluid flowing relation relative to the conduit, and which substantially prohibits the delivery of the natural gas to the accumulator. 13. A method as claimed in claim 7, and wherein the second device comprises an ion exchange membrane, and the gas to be delivered is a fuel gas which is consumed by the ion exchange membrane, and wherein both the fuel gas and the natural gas is delivered to the ion exchange membrane.14. A method as claimed in claim 7, and wherein the second device comprises an ion exchange membrane, and the gas to be delivered is a fuel gas which is consumed by the ion exchange membrane, and wherein only the fuel gas is delivered to the ion exchange membrane.15.
