Abstract: PROBLEM TO BE SOLVED: To make reaction rate sufficiently large and to miniaturize a desulfurization tower and a regeneration tower by performing both sulfurization reaction and regeneration reaction by gas-liquid reaction. SOLUTION: The dry desulfurization device is equipped with a spray device 7 of molten salt, in which at least a part of salt is melted to produce molten salt and this molten salt is mixed into a crude gas, and with a desulfurization chamber 2 in which molten salt and crude gas are introduced and brought into contact with each other and at least a part of molten salt is allowed to react with sulfur-containing gas in crude gas and a compound containing sulfur is produced and sulfur content in crude gas is removed. Since desulfurization reaction and gas-liquid reaction are performed, its reaction rate is made sufficiently large and as a result, the device is miniaturized.

Abstract: PROBLEM TO BE SOLVED: To retard the deposition of carbon, make temperature distribution uniform, and make power generation possible for a long time even if fuel having the reforming temperature lower than Boudouard's reaction temperature is used. SOLUTION: A fuel cell has means 1 for supplying fuel to be reformed at 450 deg.C or lower, means 2 for gasifying and reforming the fuel, temperature control means 3 for quickly increasing the reformed hydrogen containing gas from 450 deg.C to 600 deg.C and supplying it with this temperature kept, and power generating means 4 for generating power by reacting temperature controlled fuel with an oxidizing agent separately supplied. The power generating means 4 has at least a fuel electrode 5 to which the temperature controlled fuel is supplied and an oxidizing agent electrode 7 facing the fuel electrode 5 through an electrolyte layer 6 to constitute a unit cell, and a plurality of unit cells may be stacked to constitute a stacked body. Fuel is selected from methanol, ethanol, dimethyl ether, and propane.

Abstract: PURPOSE:To make the temperature distribution in the plane direction of a unit cell even, so as to reduce the resistance and increase the efficiency, by letting flow an oxidizer gas and a coolant in the opposite directions, in a fuel cell. CONSTITUTION:To cooling plates 14a to 14e, a coolant flows in the direction (the reverse direction) opposite to the flow of an oxidizer shown as Q in unit cell laminate blocks 15a to 15d. By letting flow the coolant and the oxidizer in the opposite directions, both gases absorb the heat from the different directions respectively, and as a result, the temperature distribution in the plane direction of the unit cell is made even. The passage of the coolant is made opposite to the flow of the oxidizer, and at the same time, the thermal conductivity of the coolant is suppressed low in the level to generate no thermal conduction between the oxidizer and the coolant.

Abstract: PURPOSE:To form a collector plate having legs disposed densely, having a large leg height, and having a small aperture part surface on a surface to be tightly applied to an electrode from a single plate by bending a thin metal plate into a wavy form for the collector plate. CONSTITUTION:A collector plate 20 is formed by applying bend work to a metal thin plate to be formed in a wavy form. where a width (a) at a peak part of each crest of the wavy form is set to be larger than a width (b) at a foot part. A surface where an electrode gets in contact is formed flat, and a number of small holes 23 are provided in it. When the electrode gets in contact with the collector plate 20, each trough part becomes an aperture part to the electrode, where the width (a) can be kept large in spite of the narrow aperture part because a>b at the peak part. Contact resistance can thus be reduced. In this form, the collector plate 20 can be set high relatively freely. Where the whole height of the collector plate 20 is set at 2.5mm-4mm, with a passage length set at 1m, pressure loss is 30mmAg/300mmAq. This pressure loss gives the optimum system efficiency of a cell.

Abstract: PURPOSE:To provide a fuel cell of a high reliability at a low cost by eliminating requirements imposed on a separator constituent member about high accuracy of fabrication, CONSTITUTION:A spring member 14 is inserted between an edge plate 13 of a separator 1 and a separator plate 10 to accomplish a soft structure, and thereby eventual dimensional error between the electromotive part when they are stacked and the edge plate 13 of separator 1 can easily be absorbed by deformation of the spring member 14, which eliminates requirement about high accuracy of fabrication. The rigidity of the edge is lowered by forming the spring member 14 from a plurality of projecting pieces which are supported by the separator 1 in cantilever form. which makes it easier to absorb the dimensional error perfectly. High fabrication accuracy is no more required of the separator 1 by extending the edge plate 13 so as to overlap in the plane direction on electrodes 8, 9 in the adjacent separator 1 and current collectors 6, 7. Thus the costs cure suppressed, and the sealing performance is enhanced.

Abstract: PURPOSE:To intend uniformity of inactive gas temperature, with which temperature distribution of a laminated structure can be uniformed in a lamination direction as well as in a in-face direction, by stirring inactive gas filled in a container while being circulated with a bulkhead put between the laminated structure and the wall of the container. CONSTITUTION:Heat of reaction transmitted to the outside face of a laminated structure 3 is transmitted in part to inactive gas 25, which is heated to go up through an inside flow path 35 and to create current (A). On the other hand, in an outside flow path 37, the inactive gas 25 is down in temperature while transmitting heat to the heat insulating wall 23 thereof to create downward current (B). The downward current (B) inflows following the upward current (A) as indicated by an arrow line (C), while the upward current (A) inflows following the downward current (B) as indicated by an arrow line (D), so that the natural convection of the inactive gas 25 is performed around a bulkhead 31 to stir atmospheric gas. It is thus possible to intend uniformity of the temperature of the inactive gas 25 with which temperature distribution of the laminated structure 3 is also uniformed in up-and-down lamination directions.

Abstract: PURPOSE:To provide uniform temp. distribution and enhance the efficiency by setting the coefficient of heat transfer from an oxidating agent gas to a flow path therefore so that heat transfer will scarcely be generated between oxidating gases each other of adjoining unitary cells. CONSTITUTION:In the strata structure 11 of a fuel cell 11, unitary cell laminate blocks 15a-15e are furnished between five cooling plates 14a-14e. The flow path 18 in these cooling plates face the flow of oxidating agent and is suppressed low in a degree so as not to generate heat transfer between the oxidating agent and cooling agent. In the cooling plates 14a-14e the cooling agent in the stream indicated by arrow c flows in the direction facing the oxidating agent in the stream as Q in blocks 15a-15e. The temp. distribution on the strata structure 11 in the plane direction can be suppressed uniform by suppressing low the coefficient of heat transfer of the flow path 18 to the cooling agent or oxidating agent in such a degree as not to generate heat transfer between the oxidating and cooling agents.

Abstract: PURPOSE:To cool all devices in uniform temperature distribution by setting the sectional areas of the cooling passages to correspond to the heat generation distribution of the respective devices. CONSTITUTION:The sectional areas of cooling passages 6 which are provided along the holes 2 for containing the devices 3 of the block 1 are set to correspond to the heat generation distribution of the devices 3. For example, when the devices 3 have heat generation sources at the upper position, the sectional area of the upper part of the passage 6 is set larger than that of the lower part. Then, the heat sink amount to the coolant in the passage 6 from the upper part of the device 3 becomes larger than that from the lower part, and the entire devices can be cooled so that the uniform temperature distribution is obtained over the entire devices.
