摘要： 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 unit 34 including a Cu—Zn catalyst receives a supply of a crude fuel gas containing the air flown through a second fuel supply conduit 64. The crude fuel gas is subjected to the steam reforming reaction and the oxidation reaction proceeding inside the reformer unit 34. A resulting hydrogen rich gaseous fuel is discharged to a third fuel supply conduit 65. The reformer unit 34 includes an upper stream reaction unit 80 and a lower stream reaction unit 81. Both the reaction units 80 and 81 have honeycomb structures, wherein the total sectional area of the flow path in the upper stream reaction unit 80 is made smaller than the total sectional area of the flow path in the lower stream reaction unit 81. This arrangement causes the gas flowing through the reformer unit 34 to 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.

摘要翻译： 本发明涉及一种从烃和蒸汽产生富氢气体的燃料重整装置。 从烃和蒸汽产生富氢气体的蒸汽重整反应是吸热的。 已知的技术通过与蒸汽重整反应并行进行的放热氧化反应来提供蒸汽重整反应所需的热量。 然而，这种已知技术可能导致燃料重整装置中剧烈氧化反应区域中的过度温度升高。 包含Cu-Zn催化剂的重整单元34接收含有通过第二燃料供应管道64流动的空气的粗燃料气体的供应。 原料燃料气体进行蒸汽重整反应，氧化反应在重整单元34内进行。 得到的富氢气体燃料被排放到第三燃料供应导管65。 重整单元34包括上游反应单元80和下游反应单元81。 反应单元80和81均具有蜂窝结构，其中上游反应单元80中的流路的总截面积小于下游反应单元81中的流路的总截面积。 这种布置使得流过重整单元34的气体在上游侧具有比在下游侧更高的流速。 上游侧的较高的流速将剧烈的氧化反应的面积扩大到下游部分，并使上游侧产生的热能够有效地传递到下游部分。 因此，能够有效地防止上游侧的温度上升过高。

摘要： The invention improves operability in forming a catalyst electrode, and improves performance of a fuel cell. A catalyst-loaded carbon is dispersed in a mixed solution of an azeotropic solvent and ion exchanged water. An electrolyte solution is added to the dispersed solution. A solvent, such as ethanol or the like, is added to adjust the viscosity and the water content of the solution, thereby providing an electrode catalyst solution. The use of the obtained solution as an ink for forming a catalyst layer through printing improves printing characteristic and drying characteristic.

摘要： A separator for an electrochemical fuel cell provides a path for a fuel gas or an oxidative gas to an electrode and functions as a wall of a unit cell of the electrochemical fuel cell. The separator comprises a conductive metal plate, a conductive coating membrane, and a tight coating membrane. The conductive coating membrane coats the conductive metal plate where the separator contacts the electrode. The tight coating membrane coats the conductive metal plate where the conductive coating membrane does not coat the conductive metal plate. A conductivity of the conductive coating membrane is higher than the tight coating membrane, and the tight coating membrane has a tighter adhesion to the conductive metal plate than the conductive coating membrane. The conductive coating membrane comprises carbon, a precious metal, or an alloy of nickel and chromium. The tight coating membrane comprises a close-grained resin. In the electrochemical fuel cell including the separator, the electric resistance between the separator and the electrode can be restrained low, and a rust problem caused by coming-off of the conductive coating membrane from the conductive metal plate can be avoided with high reliability.

摘要： When at least either one of the output voltage and internal resistance of a plurality of stacked unit cells and the humidity of oxidizing gas being discharged has deviated from the tolerance, the supply conditions of oxidizing gas to the polyelectrolytic fuel cell are changed. Specifically, when output voltage had decreased, when internal resistance has increased, or when the humidity of discharge gas has increased, the flow rate of oxidizing gas is increased, or its pressure increases, or the humidity of oxidizing gas is reduced. As a result, moisture inside the cell is removed and flooding and the resulting falls in output voltage are prevented. In addition, the generation of hydrogen gas in the passages for oxidizing gas is contained.

摘要： An improved fuel cell makes uniform partial gas pressure of a fuel gas flowing through a gas passage formed between an electrode and a separator of a fuel cell, activating an electrode reaction in a whole region of the electrode surface along the gas passage. The inlet and outlet for the fuel gas are disposed on a diagonal line of the separator to define a gas passage such that fuel gas smoothly flows even though portions of the passage away from the diagonal line. This may reduce the separator size and improve the volumetric efficiency of the fuel cell and the diffusibility of fuel gas as well as the drainage of water produced by the electrode reaction.
