A membrane assembly to be joined to a reactor chamber of a hydrogen generator, which comprises a membrane; and a membrane support comprising a sintered porous metal. A reactor assembly comprising a reaction chamber containing a porous metal substrate, two membrane assemblies, a fuel supply, a reaction fuel supply line, and a tail gas supply line and a reaction product line. Methods associated with the hydrogen generator, membrane assembly and reactor assembly.

대표청구항 ▼

We claim: 1. A method to generate hydrogen from a reaction fuel, the method comprising: providing a hydrogen membrane reactor having a combustion chamber centrally disposed in fluid connection with and in heat exchange relationship between a pair of reaction chambers wherein the reaction chambers each communicate with a membrane assembly on either side of the centrally disposed combustion chamber, each membrane assembly having at least a first and second membrane and a porous membrane support, wherein the first membrane is positioned on a first surface of the membrane support and the second membrane is positioned on a second surface of the membrane support; transporting a reaction fuel to each reaction chamber through a first supply line; transporting air to the combustion chamber through an air supply line; transporting combustion fuel to the combustion chamber through a combustion fuel supply line; reacting the combustion fuel in the combustion chamber to provide heat and combustion by-products; reacting the reaction fuel with water in the reaction chamber to produce hydrogen and tail gases; and removing the hydrogen from the reaction chamber through the membrane supports of the membrane assemblies via a reaction product line. 2. A method to generate hydrogen from a first reaction fuel, the method comprising: providing a membrane assembly to be joined to a reaction chamber of a hydrogen generator having a hydrogen plenum to form a leak tight reactor sub-assembly on each side of a central combustion chamber, wherein each of the membrane assemblies comprises a first and a second membrane; and a membrane support, wherein the first membrane is positioned on a first surface of the membrane support, the second membrane is positioned on a second surface of the membrane support, and wherein the membrane support is connected to the hydrogen plenum; reacting the first reaction fuel in the reactor chambers to provide a reaction product comprising hydrogen and tail gases; and separating the hydrogen from the tail gases in the reaction product through the membrane assemblies. 3. The method of claim 2, further comprising: replacing the first reaction fuel in the reactor chamber with a second reaction fuel, whereby replacing the first reaction fuel with the second reaction fuel results in an uninterrupted hydrogen production. 4. A method to generate hydrogen from a reaction fuel comprising: providing a pair of membrane assemblies on opposite sides of a generally elongated reaction chamber of a hydrogen generator having a hydrogen plenum, wherein each of the membrane assemblies comprises a first membrane, a second membrane; and a membrane support structure therebetween having a plurality of spaces therein, and wherein the spaces within the membrane support are connected to the hydrogen plenum; reacting the reaction fuel in the reactor chamber to provide a reaction product comprising hydrogen and tail gases; separating the hydrogen from the tail gases in the reaction product through the membrane assemblies; and routing the tail gases from the reaction product to a combustion chamber in thermal communication with the reaction chamber. 5. The method of claim 2 wherein said fuel is a non-alcohol fuel. 6. The method of claim 5 wherein said reacting the first reaction fuel is carried out in an operating temperature range of from about 575 C to about 650 C. 7. The method of claim 1 further comprising routing the tail gases into the combustion chamber. 8. The method of claim 5 further comprising routing the tail gases into the combustion chamber. 9. The method of claim 4 wherein said fuel is a non-alcohol fuel. 10. The method of claim 7 wherein said fuel is a non-alcohol fuel.
