摘要： A paste-like ink is prepared by dissolving camphor in an alcoholic solvent and dispersing fine carbon particles with a catalyst carried thereon in the solvent (step S100). A sheet-like electrode-forming member is formed on an electrolyte membrane by screen printing the paste-like ink thus obtained (step S102). The electrode-forming member is dried at 80° C. for one hour, in order to deposit camphor included in the electrode-forming member as a pore-forming agent (step S104). The electrode-forming member and the electrolyte membrane are joined with each other by hot pressing (step S106). The joint body of the electrode-forming member and the electrolyte membrane is dried under vacuum at 80° C. for three hours, in order to sublimate and remove camphor depositing in the electrode-forming member (step S108). This gives an electricity-generating layer that is a joint body of an electrode having a plurality of pores and the electrolyte membrane. The manufacturing process of the invention thus gives a joint body of an electrode having sufficient gas permeability and electrical conductivity and an electrolyte membrane.

摘要： In an apparatus A in which electrode powder 10 is allowed to adhere via the electrostatic force to an electrolyte membrane that serves as a substrate 2 so as to form a catalyst layer, a screen 5 is held in a state of non-contact with the substrate 2, and a voltage is applied therebetween. The electrode powder 10 is allowed to adhere to an elastic feed roller 7, and the feed roller 7 is allowed to rotate in contact with the screen 5 by pressure. The electrode powder 10 is dispersed toward the substrate 2 so as to stably adhere thereto via both the electrostatic force and the extruding force of the elastic body.Variation of thickness and collapse of the outline are extremely reduced on the catalyst layer to be transferred and formed on the substrate (electrolyte membrane) via the electrostatic force using a conventionally used mesh-like screen so as to obtain a membrane electrode assembly with a high product manufacturing accuracy.

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： In a catalyst electrode 23, a plurality of catalyst clusters 30 and a plurality of electrolyte clusters 32 are connected and entwined with each other. Each catalyst cluster 30 is formed by aggregation of a plurality of carbon particles 36 with a catalyst 34 carried thereon, and the surface of the catalyst cluster 30 is coated with an electrolyte layer 38. Each electrolyte cluster 32 is formed by aggregation of an electrolyte. A supply of ions is fed to the catalyst 34 for the electrochemical reaction via the electrolyte layer 38. The electrolyte clusters 32, on the other hand, ensure the pathway of ions moving from an electrolyte film 21 towards a gas diffusion electrode 25. This arrangement of the present invention does not require the thick electrolyte layer 38 for ensuring the sufficient transmission of ions but enables a sufficient amount of gas (oxygen) to be fed to the catalyst 34.

摘要： A key-phrase detection and verification method that can be advantageously used to realize understanding of flexible (i.e., unconstrained) speech. A "multiple pass" procedure is applied to a spoken utterance comprising a sequence of words (i.e., a "sentence"). First, a plurality of key-phrases are detected (i.e., recognized) based on a set of phrase sub-grammars which may, for example, be specific to the state of the dialogue. These key-phrases are then verified by assigning confidence measures thereto and comparing these confidence measures to a threshold, resulting in a set of verified key-phrase candidates. Next, the verified key-phrase candidates are connected into sentence hypotheses based upon the confidence measures and predetermined (e.g., task-specific) semantic information. And, finally, one or more of these sentence hypotheses are verified to produce a verified sentence hypothesis and, from that, a resultant understanding of the spoken utterance.
