    摘要: A method for coating a sealant (39) on a separator (40) for a fuel cell. The separator has a sealing groove (118) formed therein, and widths of the sealing groove at a coating-start portion (39a) and a coating-end portion (39b) of the sealant are made greater than widths of remaining portions of the sealing groove. The sealant coating-start portion and the coating-end portion are made to intersect at a place where the width of the sealing groove is large. Adhesion between the coating-start portion and the coating-end portion is improved, and also, degrees of freedom of a sealant coated position increase, and sealability of a cell for a fuel cell is improved.

    摘要: A hydrostatic guide system including a guide table, a transfer table, a floating amount sensor attached to the transfer table, and a control unit. The transfer table has an inner portion, in which a magnetic attraction unit including a yoke and an electromagnet is embedded, and an outer shell portion, which covers the side surface and the upper surface of the inner portion. After the inner portion houses the yoke and the electromagnet, a gap around the yoke and the electromagnet is filled with a material having appropriate strength, so that the inner portion is integrated with the outer shell portion, and the transfer surface is flattened as whole. A surrounding groove is provided around the transfer table, and pressurized fluid supplied into the groove is jetted out to the guide table.

    摘要: The present invention is intended to provide a process for producing an electrolyte membrane-bonded electrode having excellent power generation property when constitutes an electrode assembly, and a varnish composition for an electrolyte, by the use of which an electrolyte membrane-electrode bonded structure capable of retaining excellent power generation property is obtained. A process for producing a first electrolyte membrane-bonded electrode comprises applying, onto an electrode, a water-containing dispersion containing a perfluorosulfonic acid polymer, an organic solvent A and water and having a perfluorosulfonic acid polymer content of 0.5 to 20% by weight and then applying, onto the resulting film, a solution of sulfonated polyarylene in an organic solvent B, to form an electrolyte membrane. A process for producing a second electrolyte membrane-bonded electrode comprises applying, onto an electrode, a solution or dispersion containing a proton-conductive polymer, an organic solvent B and water and having a water content of 25 to 50% by weight and then applying, onto the resulting film, a solution or dispersion containing a proton-conductive polymer, an organic solvent B and water and having a water content of less than 25% by weight, to form an electrolyte membrane. A process for producing a third electrolyte membrane-bonded electrode comprises applying, onto an electrode, a varnish composition 6 obtained by dissolving a sulfonated polymer in a solvent containing an organic solvent C, an organic solvent D and water to form an electrolyte membrane, said organic solvent C being a good solvent for the sulfonated polymer and having a higher boiling point than that of other solvent components, said organic solvent D having a boiling point of not lower than 50° C. and being not a good solvent for the sulfonated polymer when used alone but causing a solubility region of the sulfonated polymer to appear when mixed with the organic solvent C and/or the water. The varnish composition 6 of the invention is a varnish composition obtained by dissolving the sulfonated polymer in a solvent containing an organic solvent C, an organic solvent D and water.
