Definitions
- the present invention relates to a hydrogen generation apparatus that generates a hydrogen-containing gas by reacting a hydrocarbon compound and water, a method for manufacturing the same, and a fuel cell system using the same, and more particularly to a water evaporation section.
- a power generation device composed of a fuel cell is a reformed gas containing hydrogen, carbon dioxide, carbon monoxide, and unreacted methane and steam by a steam reforming reaction using a hydrocarbon compound and steam as raw materials. Is generated. Next, carbon monoxide that is harmful to the fuel cell is removed by a carbon monoxide reduction unit such as a transformation unit or a selective oxidation unit to generate fuel gas. Then, power is generated by a fuel cell using the obtained fuel gas.
- the steam required for the steam reforming reaction is obtained by evaporating water in the evaporation section provided upstream of the reforming section.
- the heat of combustion exhaust gas obtained by burning unused fuel gas discharged from the fuel cell in the combustion section is usually used as a heat source required for evaporation.
- FIG. 6 is a cross-sectional view showing a configuration of a conventional hydrogen generator.
- the conventional hydrogen generator includes a heating source 2 composed of a burner (hereinafter referred to as “burner”), a reforming catalyst 3, a shift catalyst 4, a selective oxidation catalyst 5, an evaporator 8 and the like.
- the heat insulation material 14 to insulate is provided at least. At this time, hydrocarbons and water as raw materials are supplied from the raw material supply port 7, and the combustion gas of the burner 2 is exhausted from the exhaust port 6. Further, the entire hydrogen generator is insulated by the heat insulating material 14.
- the reforming catalyst 3 containing ruthenium as a main component causes the mixed gas of the raw material and steam to react with hydrogen, carbon dioxide, carbon monoxide, and a reformed gas containing unreacted methane and steam. Further, the carbon monoxide contained in the reformed gas reacts with the water vapor in the reformed gas by the shift catalyst 4, and the concentration is reduced to about 1% or less. Further, the reformed gas is mixed with the air supplied from the air supply port 12, and the carbon monoxide is selectively burned and removed by the selective oxidation catalyst 5 to generate fuel gas.
- the generated fuel gas is supplied from the fuel gas outlet 13 to the fuel cell.
- the water vapor supplied to the reforming catalyst 3 is obtained by heating water with the combustion gas combusted by the burner 2 in the evaporation section 8.
- the evaporation part 8 is comprised from the inner cylinder 9, the outer cylinder 10, and the helical rod 11 pinched
- the raw material and water supplied from the raw material supply port 7 are heated by the combustion gas generated in the burner 2 while flowing down the spiral space 8B separated by the spiral rod 11.
- Fig.7 (a) is sectional drawing which shows an example of the conventional evaporation part.
- FIG. 2B is a cross-sectional view showing another example of a conventional evaporation unit.
- FIG. 3C is a cross-sectional view showing still another example of a conventional evaporation unit.
- the evaporator 8 shown in FIG. 7A is obtained by providing a concave spiral rib 15 inside the outer cylinder 10 and intimately combining it with the inner cylinder 9. At this time, the water to be evaporated flows down the spiral space between the inner cylinder 9 and the outer cylinder 10.
- the evaporation section 8 shown in FIG. 7 (b) is obtained by providing a convex spiral rib 16 on the outer side of the inner cylinder 9 and intimately combining it with the outer cylinder 10. At this time, the water to be evaporated flows down in a spiral space between the inner cylinder 9 and the outer cylinder 10 as described above.
- the evaporation part 8 shown in FIG.7 (c) is what the pipe
- Patent Document 1 since the evaporation section shown in Patent Document 1 is configured to flow water in a spiral shape in order to secure a heat transfer area necessary for evaporation, the inner cylinder 9 and the spiral rod 11, and the outer cylinder 10 and the spiral rod. 11 must be brought into close contact with each other. This is because if there is a gap between them, non-evaporated water flows down through the gap and a part of the water is supplied to the reforming catalyst 3 without being evaporated. As a result, the water flowing down to the reforming catalyst 3 partially lowers the temperature of the reforming catalyst 3, and the hydrogen generation capability is significantly reduced.
- the rapid change in the temperature of the reforming catalyst 3 causes cracking or pulverization of the reforming catalyst 3, which has a problem of adversely affecting the life of the hydrogen generator.
- the evaporator 8 is heated by the high-temperature combustion gas from the downstream side toward the upstream side, the downstream side is at a higher temperature than the upstream side. Therefore, the water that flows down through the gap between the spiral rod 11 and the inner cylinder 9 or the outer cylinder 10 is rapidly heated and instantaneously boiled in order to flow down to a higher temperature downstream side in a short time. Produce. Then, when explosive bumping occurs, the gas in the hydrogen generator is instantaneously pushed out from the fuel gas outlet 13 to the fuel cell.
- any reaction of the reformed gas sent to the fuel cell instantaneously by the reforming catalyst, the shift catalyst, and the selective oxidation catalyst becomes insufficient.
- the reformed gas has a small amount of hydrogen and a high carbon monoxide concentration. Therefore, the fuel cell has a problem that power generation is stopped due to hydrogen shortage or carbon monoxide poisoning.
- the ribs 15 and 16 are formed by extrusion, so that the extrusion height is limited.
- the tip of the rib is required unless the height of the extruded rib is about 2 mm or less. Since the wall thickness of the material becomes thinner, cracks occur. Therefore, the flow path width of the space between the inner cylinder 9 and the outer cylinder 10 through which the evaporating water flows is about 2 mm or less. As a result, since the flow path width is narrow and the pressure loss during evaporation increases, there is a problem that the energy for pushing the raw material supplied together with water at a high pressure increases.
- the flow path width of the evaporating water and the pressure loss of the evaporating part are design factors, and it is desirable that they can be arbitrarily designed.
- the diameter of the pipe 17 that can be wound is inevitably determined depending on the diameter of the inner cylinder 9.
- the diameter of the pipe 17 that can be wound is about 10 mm or less.
- the inner diameter of the pipe 17 is about 8 mm, and the flow path that flows when water evaporates is narrow, so there is a problem that the pressure loss increases.
- This invention solves the said conventional subject, and it aims at implement
