A method of manufacturing a reinforcement layer comprises a preparatory step of preparing to-be-wound fiber, and a formation step of forming an uncured sheet layer including multiple layers of the to-be-wound fiber stacked on an outer circumferential surface. In the formation step, the to-be-wound fiber is wound on the outer circumferential surface in such a manner that, regarding an outer layer of the uncured sheet layer and an inner layer of the uncured sheet layer closer to the outer circumferential surface than the outer layer and adjacent to the outer layer in a stacking direction of the to-be-wound fiber, two end portions of the outer layer are located between two end portions of the inner layer in an axis direction extending along a center axis of a winding target member.

Method of manufacturing reinforcement layer

There is provided a manufacturing method of a tank including a liner. The manufacturing method comprises (A) a process of winding fibers in a sheet-like form impregnated with a resin on a mandrel having a higher rigidity than rigidity of the liner and heating and curing the wound fibers in the sheet-like form to form a sheet layer; (B) a process of pulling out the mandrel from the sheet layer; and (C) fitting the liner into the sheet layer, after the process (B).

The present invention is directed to a fuel reformer device that produces a hydrogen rich gas from a hydrocarbon and steam. The steam reforming reaction that produces the hydrogen rich gas from the hydrocarbon and steam is endothermic. A known technique supplies heat required for the steam reforming reaction by an exothermic oxidation reaction proceeding in parallel with the steam reforming reaction. This known technique may, however, cause an excessive temperature rise in an area of the vigorous oxidation reaction in the fuel reformer device. A reformer unitincluding a Cu&#x2014;Zn catalyst receives a supply of a crude fuel gas containing the air flown through a second fuel supply conduit. The crude fuel gas is subjected to the steam reforming reaction and the oxidation reaction proceeding inside the reformer unit. A resulting hydrogen rich gaseous fuel is discharged to a third fuel supply conduit. The reformer unitincludes an upper stream reaction unitand a lower stream reaction unit. Both the reaction unitsandhave honeycomb structures, wherein the total sectional area of the flow path in the upper stream reaction unitis made smaller than the total sectional area of the flow path in the lower stream reaction unit. This arrangement causes the gas flowing through the reformer unitto have the higher flow velocity on the upstream side than on the downstream side. The higher flow velocity on the upstream side extends the area of the vigorous oxidation reaction to the lower stream portion and enables the heat generated on the upstream side to be effectively transmitted to the lower stream portion. This arrangement thus effectively prevents an excessive temperature rise on the upstream side.

Fuel reformer device

A control apparatus for a reformer and a method of controlling the reformer are provided. The reformer gasifies a reformate fuel by a reforming reaction, supplies the obtained reformate gas to an energy converter to convert the reformate gas into energy of another form, and heats the reformate fuel by burning emission containing unreacted flammable gas produced in the energy converter. The control apparatus comprises a reforming amount assessing device for assessing the amount of the reformate fuel to be gasified, and an emission amount assessing device for assessing the amount of emission to be supplied into the reformer on the basis of the assessed amount of reformate fuel. When using the unreacted hydrogen gas generated in a fuel cell for heating the reformate fuel, the unreacted hydrogen gas and combustion aid gas can be controlled so that the reformate fuel is heated properly.

Control apparatus for reformer and method of controlling reformer using control apparatus

A fuel reformer suited for mounting on a vehicle is provided. A raw material gas containing methanol and water is vaporized at a vaporization section The vaporized gas flows horizontally to a reforming section with monolithic catalyst The reforming section is divided into two sides, a front side and a rear side with an interconnecting pipe bent at 180 degrees, for connecting the front and rear sides. By making the material gas flow horizontally, even when the reformer is mounted to a vehicle which has a larger space in its horizontal direction than in its vertical direction, especially a small passenger car, the contact time period between gas and catalyst can be extended. By bending the reforming section by 180 degrees, the size of the reformer can be reduced so that the reformer is suited for mounting on a vehicle having limited space. Because the vaporization section and the CO reducing section can be placed adjacent to each other, by using heat generated at the CO reducing section, the heat loss during pre-heating of the methanol and water can be reduced.

Fuel reformer for mounting on a vehicle

A carbon monoxide reducing device supplies oxygen to a reformate gas obtained through a reforming reaction so as to oxidize carbon monoxide contained in the reformate gas by means of the oxygen and thereby reduces a concentration of carbon monoxide contained in the reformate gas. This carbon monoxide reducing device is equipped with an oxygen supply amount controller designed to oxidize CO. The oxygen supply amount controller controls an amount of oxygen supplied to oxidize carbon monoxide contained in the reformate gas based on an amount of supply of fuel contributing to the reforming reaction. Thereby, the amount of oxygen for oxidizing carbon monoxide contained in the reformate gas is adjusted appropriately, and a high-quality reformate gas can be obtained.

Carbon monoxide reducing device for reducing carbon monoxide in a reformate gas

The structure of the present invention enables all catalysts packed in a cooling layer to be kept in an active temperature range, thereby sufficiently reducing the concentration of carbon monoxide included in a hydrogen-rich gas. A supply of water is fed through a water inlet pipe 40 to a selective CO oxidizing unit 34 of a reformer 30. The heat of vaporization of the supplied water directly cools down selective CO oxidizing catalysts 50 stored in the selective CO oxidizing unit 34. This enhances the cooling efficiency and enables all the selective CO oxidizing catalysts 50 stored in the selective CO oxidizing unit 34 to be maintained in the active temperature range, thus sufficiently reducing the concentration of carbon monoxide included in a resulting gaseous fuel.
