Abstract: A conveying apparatus for a separator for a fuel cell includes: a conveying portion configured to hold an intermediate part of the separator and lift the separator; and restricting portions configured to restrict the opposite ends of the separator to warp the intermediate part of the separator in the lifting direction when the conveying portion lifts the separator. The restricting portions are configured to release the opposite ends when the intermediate part of the separator warps in the lifting direction with a target curvature amount.

Abstract: An electrode structure 15 is received in a joint portion of frames 13, 14. A first gas diffusion layer 19 and a first gas passage forming member 21 are arranged on a first surface of the electrode structure 15. A second gas diffusion layer 20 and a second gas passage forming member 22 are formed on a second surface of the electrode structure 15. A separator 23 is joined with a surface of the frame 13 and a surface of the gas passage forming member 21. A separator 24 is joined with a surface of the frame 14 and a surface of the gas passage forming member 22. A water passage 28 is formed between a flat plate 25 of the gas passage forming member 22 and the separator 24. The water passage 28 has a depth set to a value smaller than depth of a gas passage T2 of the gas passage forming member 22. Generated water is introduced from the gas passage T2 of the gas passage forming member 22 to the water passage 28 through capillary action via communication holes 29.

Abstract: A fuel cell includes a gas channel-forming member that forms a channel for supplying a reactant gas to a plane of an electrode. A basic structure of the gas channel-forming member is a corrugated plate portion in which ridge portions and trough portions continuously alternate with each other. In the gas channel-forming member, a plurality of corrugated plate portions are interconnected. Specifically, two adjacent corrugated plate portions are interconnected so that the trough portions of one of the two connect to the ridge portions of the other corrugated plate portion. The gas channel-forming member is disposed so that the direction of alignment of the connection planes S formed by the interconnection between the trough portions and the ridge portions is parallel to the plane of the electrode. This structure improves the diffusion efficiency of the reactant gas in the gas channel.

Abstract: A separator 10 includes a separator body 11 and a collector 12. The separator body 11 prevents mixed flow of fuel gas and oxidizer gas. The collector 12 is formed from a metal lath MR in which the angle between the direction of formation of strand portions (through-hole formation portions) for forming through holes in a meshy, step-like arrangement and the direction of formation of bond portions (connection portions) for connecting the strand portions to one another is about 60 degrees. By virtue of this, the thickness of the collector 12 can be increased through reduction in pitch P. Thus, a good gas supply performance is ensured through reduction in pressure loss of introduced gas, and water generated in an MEA 30 can be well drained by capillary action which arises in the through holes.

Abstract: Making use of the feature that a high polymer is difficult to fiberize when used at below the glass transition point, a pressure-feed device (22) and part of an upstream pipe (26) are covered by a temperature regulation device (128) and the heat exchange in the temperature regulation device (128) maintains the temperature of a paste (PA) containing a water-repellent substance having a glass transition point and that passes through the pressure-feed device (22) to below the glass transition point of the water-repellent substance while coating the paste (PA) from a coating device (24).
