    • A separator includes a separator body 11 and a collector 12. The separator body 11 prevents a mixed flow of fuel gas and oxidizer gas. The collector 12 is formed from a metal lath RM in which through holes each having an opening shape assuming the form of a hexagon are formed in a meshy, step-like arrangement. This establishes a substantially linear contact mode between the collector 12 and each of the separator body 11 and a carbon cloth CC superposed on an MEA 30. This contact mode increases a contact area between the carbon cloth CC and gas and allows a necessary and sufficient contact area between the carbon cloth CC and the separator body 11. Thus, gas can be supplied efficiently, and generated electricity can be collected efficiently to thereby improve electricity generation efficiency of a fuel cell.
    • 分离器包括分离器主体11和收集器12.分离器主体11防止燃料气体和氧化剂气体的混合流动。 集电体12由金属板条RM形成,其中各孔具有呈六边形形状的开口形状,形成为网状的阶梯状布置。 这在集电器12与分离器主体11和叠加在MEA 30上的碳布CC之间建立了基本上线性的接触模式。该接触模式增加了碳布CC和气体之间的接触面积,并允许必要和充分的接触 炭布CC与分离器主体11之间的区域。因此,可以有效地提供气体,并且可以有效地收集发电,从而提高燃料电池的发电效率。

    • 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. The generated water in the water passage 28 is moved to a downstream side of the water passage 28 by pressure caused by oxidization gas. This prevents corrosion of the cathode side electrode catalyst layer and improves durability of the anode side gas passage forming member. As a result, a fuel cell capable of preventing decrease of power generation is provided.

    • An electrode structure 15 is accommodated in a joint portion of frames 13 and 14. A first gas diffusion layer 19 and a first gas passage forming member 21 are laid on a first surface of the electrode structure 15, and a second gas diffusion layer 20 and a second gas passage forming member 22 are laid on a second surface of the electrode structure 15. A separator 23 is joined to surfaces of the frame 13 and the gas passage forming member 21, and a separator 24 is joined to surfaces of the frame 14 and the gas passage forming member 22. A porous layer 26 having continuous pores is located between the gas passage forming member 22 and the separator 24. A drainage promoting member 30 formed of a porous material having continuous pores is provided to communicate with a downstream end of a second gas passage T2 of the second gas passage forming member 22 and to communicate with a downstream end of the continuous pores of the porous layer 26. Generated water that has been drawn into the porous layer 26 from the second gas passage T2 by capillary action flows downstream by surface tension of water, and is then drawn into the drainage promoting member 30. The water drawn in by the drainage promoting member 30 is discharged into a discharging passage by fluid pressure of oxidation off-gas that flows from the second gas passage T2 into the continuous pores of the drainage promoting member 30. Accordingly, a fuel battery is provided in which generated water is prevented from remaining in the second gas passage T2 of the cathode side second gas passage forming member 22, and it is possible to prevent the power generation performance from being lowered by insufficient supply of oxidation gas to the electrode structure 15.

    • A collector 12 which serves as a gas diffusion layer for a fuel cell; i.e., a metal lath MR, is formed by a method consisting of a first step and a second step. In the first step, while an upper blade UH is positioned at a first machining position along the width direction of a stainless steel sheet S, generally hexagonal through holes are formed in the stainless steel sheet S at two positions which are biased from each other by a machining pitch. In the second step, while the upper blade UH is positioned at a second machining position along the width direction of the stainless steel sheet S, generally hexagonal through holes are formed in the stainless steel sheet S at two positions which are biased from each other by the machining pitch. The first step and the second step are alternated repeatedly, thereby forming the metal lath MR having a uniform shape and a predetermined thickness.
