摘要:
A bypass plate and an intermediate plate are interposed between a stack body and a negative electrode terminal of a fuel cell stack. An oxygen-containing gas passage extends through the bypass plate and the stack body. The intermediate plate has a small opening. The opening has a cross sectional area smaller than a cross sectional area of the oxygen-containing gas supply passage. The opening is formed by an extension extending into the oxygen-containing gas supply passage. The extension removes water in the oxygen-containing gas, and discharges the water into a bypass flow passage.

A fuel cell of the invention has unified a processing circuit processing a cell voltage output signal of a fuel cell stack and a connector connecting an circuit unit with terminals provided extending from separators of the fuel cell, thereby having abolished connection points (in which harnesses are attached and detached) of an electrical circuit unit with the connector. So, for connection, reliability can be improved, and downsizing is possible. Moreover, with a casing enclosing the connector and electrical circuit unit, the fuel cell can be made compact and the processing circuit can be surely protected thanks to being shielded from surroundings, thereby handling as a unit being able to be facilitated.

A fuel cell stack includes a plurality of unit cells each including a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly. The unit cells are stacked into a stack body, and the stack body is placed in a casing. Fluorocarbon resin sheets are provided between four sides of the stack body in parallel with the stacking direction of the stacked body and side plates of the casing, respectively. The fluorocarbon resin sheets fill gaps between stack body and inner surfaces of the casing.

A novel phosphatic/potash compound fertilizer and a method of producing the same are provided for improving the solubility of phosphate components contained in an incinerated ash residue of chicken droppings for efficient utilization of the ash residue, with the alkalis of the lime component origin being neutralized. Thus, at least one powder selected from among a basic potassium compound powder and a water-granulated blast furnace slag powder is admixed with an incinerated ash residue of chicken droppings, a mineral acid is added to the mixture and reactions are allowed to proceed to maintain the reaction system at a high temperature by utilizing the heat of neutralization generated by the reaction between the basic potassium compound and/or water-granulated blast furnace slag powder and the mineral acid thereby convert hardly soluble phosphatic components contained in the incinerated chicken dropping ash residue to effective components improved in solubility, while maintaining the reaction mixture at about neutrality or weak acidity.

A display unit has a metal fitting that has a minimum-required shape and size for maintaining the physical strength and electrical performance of the display unit. Parts other than the metal fitting are formed of a resin chassis frame. The resin chassis frame, lighter and thinner than a metal chassis, is adopted, because an insulating space can be eliminated while maintaining the safety and durability.

(Object) To prevent the chromaticity from changing due to the gradation in a display system for improving the blurring in an animated image where one frame is formed of two fields having different brightness.(Means for Achieving Object) According to a driving method for improving the properties of an animated image by dividing one frame into a bright field having high brightness and a dark field having low brightness where an image is displayed in the case where the gradation of the image is 190 or greater, a change in the chromaticity is great in the dark field. In order to solve this problem, the gradation properties for blue are corrected only in the dark field. The gradation properties of one color which is greatly effective on the chromaticity are changed only for the necessary gradation, and therefore, the chromaticity properties can be improved while preventing the gradation-brightness properties from being affected.
