　燃料電池用セルシール部材は、積層方向に隣り合う一対のセルアセンブリの間に介装されている。燃料電池用セルシール部材は、一対のセルアセンブリ間を弾性的に封止している。近年の燃料電池の小型化の要請により、燃料電池用セルシール部材の薄型化が検討されているが、薄型化すると、燃料電池組立時などに、燃料電池用セルシール部材が捩れたり絡んだりしやすくなる。すなわち、燃料電池用セルシール部材が変形しやすくなる。したがって、燃料電池用セルシール部材は、燃料電池において実際に使用される形状、つまりシール形状を維持したまま、搬送される方が好ましい。 The fuel cell cell seal member is interposed between a pair of cell assemblies adjacent in the stacking direction. The cell seal member for a fuel cell elastically seals between the pair of cell assemblies. In recent years, due to the demand for miniaturization of fuel cells, reduction of the thickness of fuel cell cell seal members has been studied. . That is, the fuel cell cell seal member is easily deformed. Therefore, it is preferable that the cell seal member for a fuel cell is conveyed while maintaining the shape actually used in the fuel cell, that is, the seal shape.
　この点、特許文献１には、燃料電池の金属製のセパレータを収容するための、セパレータ用トレイが開示されている。金属製のセパレータは硬質である。このため、搬送時においては、セパレータの振動やがたつきを抑制する必要がある。すなわち、セパレータを拘束する必要がある。この点、特許文献１のセパレータ用トレイには、支持部材（クッション材）が配置されている。セパレータは、上下両側から一対の支持部材に挟持された状態で、上下一対のセパレータ用トレイの間に収容される。このように、特許文献１のセパレータ用トレイの場合、上下一対の支持部材で拘束した状態で、セパレータを搬送している。 In this regard, Patent Document 1 discloses a separator tray for housing a fuel cell metal separator. Metal separators are hard. For this reason, it is necessary to suppress the vibration and rattling of the separator during conveyance. That is, it is necessary to restrain the separator. In this regard, a support member (cushion material) is disposed in the separator tray of Patent Document 1. The separator is accommodated between the pair of upper and lower separator trays while being sandwiched between the pair of support members from both the upper and lower sides. Thus, in the case of the separator tray of Patent Document 1, the separator is transported in a state of being restrained by a pair of upper and lower support members.

　仮に、特許文献１のセパレータ用トレイを燃料電池用セルシール部材に転用する場合、燃料電池用セルシール部材が、上下両側から拘束されることになる。このため、搬送中の燃料電池用セルシール部材に、継続的に上下両側から荷重が加わることになる。しかしながら、所望の性能を確保する観点からは、搬送中に、燃料電池用セルシール部材に荷重が加わらない方が好ましい。 Temporarily, when diverting the separator tray of Patent Document 1 to a fuel cell cell seal member, the fuel cell cell seal member is restrained from both the upper and lower sides. For this reason, a load is continuously applied to the cell seal member for a fuel cell being conveyed from both the upper and lower sides. However, from the viewpoint of ensuring desired performance, it is preferable that no load is applied to the fuel cell cell seal member during transportation.
　そこで、本発明は、燃料電池用セルシール部材に荷重が加わりにくく、燃料電池用セルシール部材が変形しにくいシール部材収納用トレイを提供することを目的とする。 Therefore, an object of the present invention is to provide a seal member storage tray in which a load is not easily applied to the fuel cell cell seal member and the fuel cell cell seal member is not easily deformed.
　上記課題を解決するため、本発明のシール部材収納用トレイは、エラストマー製かつ枠状の燃料電池用セルシール部材が収容されるシール部材収納用トレイであって、複数の前記シール部材収納用トレイが上下方向に積層されたトレイ積層体において、任意の前記シール部材収納用トレイを下側トレイ、前記下側トレイの上側に積み重ねられる別の前記シール部材収納用トレイを上側トレイとして、前記下側トレイと前記上側トレイとの間には、前記上側トレイとの間で隙間が確保された状態で前記燃料電池用セルシール部材を収容可能な、枠状の収容部が区画されることを特徴とする。 In order to solve the above-described problems, a seal member storage tray of the present invention is a seal member storage tray in which an elastomeric and frame-shaped cell seal member for a fuel cell is stored, and the plurality of seal member storage trays include In the tray stack stacked in the vertical direction, the lower tray is defined by using any of the seal member storage trays as a lower tray and another seal member storage tray stacked on the upper side of the lower tray as an upper tray. Between the upper tray and the upper tray, a frame-shaped storage portion is defined that can store the cell seal member for the fuel cell in a state where a gap is secured between the upper tray and the upper tray.
　上述したように、金属製で硬質のセパレータの場合、搬送時における振動やがたつきを抑制するため、セパレータを拘束する必要がある。この点、本発明のシール部材収納用トレイの収容対象物である燃料電池用セルシール部材は、柔軟なエラストマー製である。このため、金属製のセパレータと比較して、拘束の必要性が小さい。本発明のシール部材収納用トレイによると、収容部に収容された燃料電池用セルシール部材と、上側トレイと、の間に隙間が確保されている。このため、燃料電池用セルシール部材に荷重が加わりにくい。 As described above, in the case of a hard separator made of metal, it is necessary to restrain the separator in order to suppress vibration and rattling during transportation. In this regard, the cell seal member for a fuel cell, which is an object to be stored in the seal member storage tray of the present invention, is made of a flexible elastomer. For this reason, the necessity of restraint is small compared with a metal separator. According to the seal member storage tray of the present invention, a gap is secured between the fuel cell cell seal member housed in the housing portion and the upper tray. For this reason, it is difficult to apply a load to the cell seal member for the fuel cell.
　また、収容部は、燃料電池用セルシール部材と同様に、枠状を呈している。このため、燃料電池用セルシール部材が変形しにくい。したがって、本発明のシール部材収納用トレイによると、搬送時に、燃料電池用セルシール部材が、燃料電池において実際に使用される形状、つまりシール形状を維持しやすい。また、複数のシール部材収納用トレイ、つまり複数の燃料電池用セルシール部材を、トレイ積層体の状態で、まとめて搬送することができる。このため、搬送効率が高い。 Also, the housing portion has a frame shape, similar to the cell seal member for fuel cells. For this reason, the cell seal member for fuel cells is not easily deformed. Therefore, according to the seal member storage tray of the present invention, the cell seal member for the fuel cell can easily maintain the shape actually used in the fuel cell, that is, the seal shape, at the time of conveyance. In addition, a plurality of seal member storage trays, that is, a plurality of fuel cell cell seal members, can be transported together in a tray stack. For this reason, conveyance efficiency is high.

　以下、本発明のシール部材収納用トレイの実施の形態について説明する。なお、「シール部材収納用トレイ」を、適宜、「収納用トレイ」と略称する。同様に、「燃料電池用セルシール部材」を、適宜、「セルシール部材」と略称する。 Hereinafter, embodiments of the tray for storing a seal member of the present invention will be described. The “seal member storage tray” is abbreviated as “storage tray” as appropriate. Similarly, the “cell seal member for fuel cell” is appropriately abbreviated as “cell seal member”.
　＜セルシール部材の配置＞
　まず、本実施形態の収納用トレイの収容対象物かつ搬送対象物である、セルシール部材の配置について説明する。図１に、セルシール部材が配置された燃料電池の上下方向断面図を示す。図１に示すように、燃料電池９は、上下一対の端板９０と、複数のセルシール部材２と、複数のセルアセンブリ９１と、を備えている。 <Arrangement of cell seal member>
First, the arrangement of the cell seal member, which is an object to be accommodated and an object to be conveyed in the storage tray of the present embodiment, will be described. FIG. 1 is a vertical sectional view of a fuel cell in which a cell seal member is disposed. As shown in FIG. 1, the fuel cell 9 includes a pair of upper and lower end plates 90, a plurality of cell seal members 2, and a plurality of cell assemblies 91.
　セルアセンブリ９１は、電極部材９２と、上下一対のセパレータ９３と、セル内シール部材９４と、を備えている。セル内シール部材９４は、電極部材９２を、水平方向外側から囲んでいる。上下一対のセパレータ９３は、セル内シール部材９４および電極部材９２の、上下両側に配置されている。電極部材９２は、ＭＥＡ（Ｍｅｍｂｒａｎｅ　Ｅｌｅｃｔｒｏｄｅ　Ａｓｓｅｍｂｌｙ）９２０と、上下一対の多孔質層９２１と、を備えている。 The cell assembly 91 includes an electrode member 92, a pair of upper and lower separators 93, and an in-cell seal member 94. The in-cell seal member 94 surrounds the electrode member 92 from the outside in the horizontal direction. The pair of upper and lower separators 93 are disposed on both upper and lower sides of the in-cell seal member 94 and the electrode member 92. The electrode member 92 includes a MEA (Membrane Electrode Assembly) 920 and a pair of upper and lower porous layers 921.
　セルシール部材２とセルアセンブリ９１とは、上下方向に交互に積層されている。このため、任意のセルシール部材２は、上下方向に隣り合う一対のセルアセンブリ９１（具体的にはセパレータ９３）間に、介装されている。また、セルシール部材２は柔軟である。このため、任意のセルシール部材２は、上下方向に隣り合う一対のセルアセンブリ９１に、弾接している。すなわち、セルシール部材２は、上下方向に隣り合う一対のセルアセンブリ９１間を封止する部材である。上下一対の端板９０は、セルシール部材２とセルアセンブリ９１との積層体を、上下両側から挟持している。 The cell seal member 2 and the cell assembly 91 are alternately stacked in the vertical direction. For this reason, the arbitrary cell seal member 2 is interposed between a pair of cell assemblies 91 (specifically, separators 93) adjacent in the vertical direction. Moreover, the cell seal member 2 is flexible. Therefore, the arbitrary cell seal member 2 is in elastic contact with a pair of cell assemblies 91 adjacent in the vertical direction. That is, the cell seal member 2 is a member that seals between a pair of cell assemblies 91 adjacent in the vertical direction. The pair of upper and lower end plates 90 sandwich the laminated body of the cell seal member 2 and the cell assembly 91 from both the upper and lower sides.
　＜セルシール部材の構成＞
　次に、本実施形態の収納用トレイの収容対象物かつ搬送対象物である、セルシール部材の構成について説明する。図２に、セパレータの上面に配置されたセルシール部材の上面図（図１のＩＩ部分の上面図）を示す。図２に示すように、セルシール部材２は、エチレン－プロピレン－ジエンゴム（ＥＰＤＭ）をゴム成分とするゴムの架橋物製である。当該ゴムは、本発明の「エラストマー」の概念に含まれる。図２にハッチングで示すように、セルシール部材２は、単体成形品（一体物）であって、無端環状かつ四角形枠状を呈している。セルシール部材２は、シール本体２０と、上下一対のシールリップ２１（図２に一点鎖線で示す）と、を備えている。シール本体２０は、無端環状かつ四角形枠状（詳しくは、左右両辺（短辺）内側に三つずつ小さな四角形枠部を有する四角形枠状）を呈している。シールリップ２１は、シール本体２０の上下両面に形成されている。上側のシールリップ２１は、図１に示す上側のセパレータ９３に弾接している。下側のシールリップ２１は、図１、図２に示す下側のセパレータ９３に弾接している。 <Configuration of cell seal member>
Next, the configuration of the cell seal member, which is an object to be accommodated and an object to be conveyed in the storage tray according to this embodiment, will be described. FIG. 2 shows a top view of the cell seal member disposed on the top surface of the separator (a top view of a portion II in FIG. 1). As shown in FIG. 2, the cell seal member 2 is made of a rubber cross-linked product containing ethylene-propylene-diene rubber (EPDM) as a rubber component. The rubber is included in the concept of “elastomer” of the present invention. As shown by hatching in FIG. 2, the cell seal member 2 is a single-piece molded product (integrated product) and has an endless annular and rectangular frame shape. The cell seal member 2 includes a seal body 20 and a pair of upper and lower seal lips 21 (indicated by a dashed line in FIG. 2). The seal body 20 has an endless annular and quadrangular frame shape (specifically, a quadrangular frame shape having three small quadrangular frame portions inside the left and right sides (short sides)). The seal lip 21 is formed on both upper and lower surfaces of the seal body 20. The upper seal lip 21 is in elastic contact with the upper separator 93 shown in FIG. The lower seal lip 21 is in elastic contact with the lower separator 93 shown in FIGS.
　＜収納用トレイの構成＞
　次に、本実施形態の収納用トレイの構成について説明する。図３に、本実施形態の複数の収納用トレイの積層体であるトレイ積層体の上面図を示す。図４に、図３のＩＶ－ＩＶ方向断面図を示す。図５に、図４の枠Ｖ内の拡大図を示す。 <Configuration of storage tray>
Next, the configuration of the storage tray of this embodiment will be described. In FIG. 3, the top view of the tray laminated body which is a laminated body of the several storage tray of this embodiment is shown. FIG. 4 shows a cross-sectional view in the IV-IV direction of FIG. FIG. 5 shows an enlarged view in the frame V of FIG.
　図３～図５に示すように、収納用トレイ４は、帯電防止材料製であって、基部４０と、上側凹部４１Ｕと、下側凹部４１Ｄと、位置決め部４２と、複数の貫通孔４３と、複数の連結部４４と、を備えている。 As shown in FIGS. 3 to 5, the storage tray 4 is made of an antistatic material, and includes a base 40, an upper recess 41U, a lower recess 41D, a positioning portion 42, and a plurality of through holes 43. And a plurality of connecting portions 44.
　基部４０は、四角形状を呈している。上側凹部４１Ｕは、基部４０の上面に凹設されている。上側凹部４１Ｕは、セルシール部材２の下側部分と型対称の無端環状かつ四角形枠状を呈している。図５に示すように、上側凹部４１Ｕは、本体収容部４１０Ｕと、リップ収容部４１１Ｕと、を備えている。下側凹部４１Ｄは、基部４０の下面に凹設されている。下側凹部４１Ｄは、セルシール部材２の上側部分同様の無端環状かつ四角形枠状を呈している。図４、図５に示すように、上側から見て、上側凹部４１Ｕと下側凹部４１Ｄとは、上下方向に重複している。 The base 40 has a rectangular shape. The upper concave portion 41U is recessed in the upper surface of the base portion 40. The upper concave portion 41U has an endless annular and quadrangular frame shape that is type-symmetric with the lower portion of the cell seal member 2. As shown in FIG. 5, the upper concave portion 41U includes a main body housing portion 410U and a lip housing portion 411U. The lower recess 41 </ b> D is recessed on the lower surface of the base 40. The lower concave portion 41D has an endless annular and rectangular frame shape similar to the upper portion of the cell seal member 2. As shown in FIGS. 4 and 5, the upper concave portion 41 </ b> U and the lower concave portion 41 </ b> D overlap in the vertical direction when viewed from the upper side.
　図３、図４に示すように、位置決め部４２は、基部４０の外周部４００の水平方向外側に配置されている。位置決め部４２は、無端環状かつ四角形枠状を呈している。位置決め部４２は、上側かつ水平方向内側から下側かつ水平方向外側に向かって降りる階段状を呈している。 As shown in FIGS. 3 and 4, the positioning portion 42 is disposed on the outer side in the horizontal direction of the outer peripheral portion 400 of the base portion 40. The positioning part 42 has an endless annular and rectangular frame shape. The positioning part 42 has a stepped shape descending from the upper side and the horizontal inner side to the lower side and the horizontal outer side.
　図３に示すように、複数の連結部４４は、外周部４００と位置決め部４２とを水平方向に連結している。複数の貫通孔４３は、外周部４００と位置決め部４２との間に、連結部４４に仕切られた状態で、配置されている。すなわち、複数の貫通孔４３は、外周部４００と位置決め部４２とを、点線状かつ四角形枠状に、水平方向に仕切っている。 As shown in FIG. 3, the plurality of connecting portions 44 connect the outer peripheral portion 400 and the positioning portion 42 in the horizontal direction. The plurality of through holes 43 are arranged between the outer peripheral portion 400 and the positioning portion 42 in a state of being partitioned by the connecting portion 44. That is, the plurality of through holes 43 partition the outer peripheral portion 400 and the positioning portion 42 in the horizontal direction in a dotted line shape and a rectangular frame shape.
　＜トレイ積層体の構成＞
　次に、本実施形態の収納用トレイの積層体であるトレイ積層体の構成について説明する。図４に示すように、トレイ積層体Ｓにおいては、後述する収容部にセルシール部材２が収容された状態で、複数（本実施形態では６段）の収納用トレイ４が上下方向に積層されている。 <Configuration of tray laminate>
Next, the structure of the tray laminated body which is the laminated body of the storage tray of this embodiment is demonstrated. As shown in FIG. 4, in the tray stack S, a plurality (six in this embodiment) of storage trays 4 are stacked in the vertical direction in a state where the cell seal member 2 is stored in a storage portion described later. Yes.
　ここで、図４に示すように、任意（本実施形態では上から４段目）の収納用トレイ４を下側トレイ４Ｄとする。また、下側トレイ４Ｄの上側に積み重ねられる別（本実施形態では上から３段目）の収納用トレイ４を、上側トレイ４Ｕとする。 Here, as shown in FIG. 4, an arbitrary (fourth stage from the top in this embodiment) storage tray 4 is a lower tray 4D. Further, another storage tray 4 (third stage from the top in the present embodiment) stacked on the upper side of the lower tray 4D is referred to as an upper tray 4U.
　なお、下側トレイ４Ｄ、上側トレイ４Ｕの概念は、上下方向に隣り合う任意の一対の収納用トレイ４同士の、相対的な位置関係を示すものである。例えば、上から４段目の収納用トレイ４は、上から５段目の収納用トレイ４から見れば、上側トレイ４Ｕに相当する。同様に、上から３段目の収納用トレイ４は、上から２段目の収納用トレイ４から見れば、下側トレイ４Ｄに相当する。 The concept of the lower tray 4D and the upper tray 4U indicates a relative positional relationship between any pair of storage trays 4 adjacent in the vertical direction. For example, the fourth storage tray 4 from the top corresponds to the upper tray 4U when viewed from the fifth storage tray 4 from the top. Similarly, the third storage tray 4 from the top corresponds to the lower tray 4D when viewed from the second storage tray 4 from the top.
　図４に点線円で示すように、下側トレイ４Ｄと上側トレイ４Ｕとの間には、係合部Ｂが配置されている。係合部Ｂは、無端環状かつ四角形枠状を呈している。係合部Ｂは、下側トレイ４Ｄの位置決め部４２と、上側トレイ４Ｕの位置決め部４２と、が互いに係合することにより形成されている。詳しくは、下側トレイ４Ｄの位置決め部４２の上側の垂直面（水平方向外向き）と、上側トレイ４Ｕの位置決め部４２の下側の垂直面（水平方向内向き）と、が水平方向から互いに係合することにより、係合部Ｂが形成されている。係合部Ｂは、下側トレイ４Ｄと上側トレイ４Ｕとの相対的な水平方向のずれを抑制している。一方、係合部Ｂは、下側トレイ４Ｄと上側トレイ４Ｕとの相対的な上下方向の移動を許容している。このため、下側トレイ４Ｄと上側トレイ４Ｕとは上下方向に分離可能である。したがって、トレイ積層体Ｓは、上下方向に分解可能である。 As shown by a dotted circle in FIG. 4, the engaging portion B is disposed between the lower tray 4D and the upper tray 4U. The engaging part B has an endless annular and rectangular frame shape. The engaging portion B is formed by the positioning portion 42 of the lower tray 4D and the positioning portion 42 of the upper tray 4U engaging each other. Specifically, the upper vertical surface (horizontal outward) of the positioning portion 42 of the lower tray 4D and the lower vertical surface (horizontal inward) of the positioning portion 42 of the upper tray 4U are mutually viewed from the horizontal direction. The engaging part B is formed by engaging. The engaging portion B suppresses a relative horizontal shift between the lower tray 4D and the upper tray 4U. On the other hand, the engaging part B allows the relative vertical movement of the lower tray 4D and the upper tray 4U. Therefore, the lower tray 4D and the upper tray 4U can be separated in the vertical direction. Therefore, the tray stack S can be disassembled in the vertical direction.
　図４に示すように、下側トレイ４Ｄの貫通孔４３と、上側トレイ４Ｕの貫通孔４３と、は上下方向に連なっている。下側トレイ４Ｄの上面と、上側トレイ４Ｕの下面と、の間には、上下方向の隙間Ｃが区画されている。隙間Ｃは、貫通孔４３の水平方向外側、貫通孔４３と収容部Ａとの間、収容部Ａの水平方向内側の合計三箇所に配置されている。 As shown in FIG. 4, the through hole 43 of the lower tray 4D and the through hole 43 of the upper tray 4U are continuous in the vertical direction. A vertical gap C is defined between the upper surface of the lower tray 4D and the lower surface of the upper tray 4U. The gaps C are arranged at a total of three locations on the outer side in the horizontal direction of the through hole 43, between the through hole 43 and the housing part A, and on the inner side in the horizontal direction of the housing part A.
　図４、図５に示すように、下側トレイ４Ｄの上側凹部４１Ｕと、上側トレイ４Ｕの下側凹部４１Ｄと、の間には、収容部Ａが区画されている。収容部Ａは、無端環状かつ四角形枠状を呈している。収容部Ａには、セルシール部材２が収容されている。詳しくは、セルシール部材２の下側部分（シール本体２０の下側部分、下側のシールリップ２１）は、下側トレイ４Ｄの上側凹部４１Ｕに収容されている。シール本体２０の下側部分は、本体収容部４１０Ｕに収容されている。下側のシールリップ２１は、リップ収容部４１１Ｕに収容されている。また、セルシール部材２の上側部分（シール本体２０の上側部分、上側のシールリップ２１）は、上側トレイ４Ｕの下側凹部４１Ｄに収容されている。 As shown in FIGS. 4 and 5, the accommodating portion A is defined between the upper concave portion 41U of the lower tray 4D and the lower concave portion 41D of the upper tray 4U. The accommodating part A has an endless annular and rectangular frame shape. The cell seal member 2 is accommodated in the accommodating portion A. Specifically, the lower portion of the cell seal member 2 (the lower portion of the seal body 20, the lower seal lip 21) is accommodated in the upper concave portion 41U of the lower tray 4D. The lower part of the seal body 20 is housed in the body housing portion 410U. The lower seal lip 21 is accommodated in the lip accommodating portion 411U. The upper portion of the cell seal member 2 (the upper portion of the seal body 20 and the upper seal lip 21) is accommodated in the lower recess 41D of the upper tray 4U.
　図５に示すように、下側トレイ４Ｄの上側凹部４１Ｕの底面から、上側トレイ４Ｕの下側凹部４１Ｄの底面までの上下方向長さ（収容部Ａの上下方向長さ）Ｅは、セルシール部材２の横断面（セルシール部材２の延在方向に対して直交する方向の断面）における上下方向厚みＦよりも、大きい。このため、セルシール部材２の上面と、上側トレイ４Ｕの下側凹部４１Ｄの底面と、の間には隙間が確保されている。したがって、上側のシールリップ２１は、上側トレイ４Ｕに接触していない。 As shown in FIG. 5, the vertical length (the vertical length of the accommodating portion A) E from the bottom surface of the upper concave portion 41U of the lower tray 4D to the bottom surface of the lower concave portion 41D of the upper tray 4U is a cell seal member. It is larger than the vertical thickness F in the cross section of 2 (the cross section in the direction orthogonal to the extending direction of the cell seal member 2). For this reason, a gap is secured between the upper surface of the cell seal member 2 and the bottom surface of the lower recess 41D of the upper tray 4U. Therefore, the upper seal lip 21 is not in contact with the upper tray 4U.
　＜セルシール部材の搬送方法＞
　次に、本実施形態のセルシール部材の搬送方法について説明する。本実施形態のセルシール部材の搬送方法は、トレイ積層工程と、積層体搬送工程と、を有している。 <Conveying method of cell seal member>
Next, the conveyance method of the cell seal member of this embodiment is demonstrated. The transport method for the cell seal member of the present embodiment includes a tray stacking step and a stacked body transporting step.
　［トレイ積層工程］
　図６に、本実施形態のセルシール部材の搬送方法のトレイ積層工程前段の模式図を示す。図７に、同トレイ積層工程後段の模式図を示す。本工程においては、図３～図５に示すトレイ積層体Ｓを作成する。本工程は、配置ステップと、積層ステップと、を有している。 [Tray stacking process]
In FIG. 6, the schematic diagram of the tray lamination process pre-stage of the conveyance method of the cell seal member of this embodiment is shown. FIG. 7 shows a schematic diagram of the latter stage of the tray stacking step. In this step, the tray stack S shown in FIGS. 3 to 5 is created. This process has an arrangement step and a lamination step.
　図６に示すように、配置ステップにおいては、最上段の収納用トレイ４を除く、全ての収納用トレイ４の上側凹部４１Ｕに、セルシール部材２を配置する。まず、射出成形されたセルシール部材２を、金型（図略）から収納用トレイ４の上側凹部４１Ｕまで、搬送装置８により、搬送する。次に、セルシール部材２を、収納用トレイ４の上側凹部４１Ｕに、配置する。なお、搬送、配置の際、セルシール部材２の上面は、搬送装置８の吸着ノズル８０により、吸着される。 As shown in FIG. 6, in the arrangement step, the cell seal members 2 are arranged in the upper concave portions 41U of all the storage trays 4 except the uppermost storage tray 4. First, the injection-molded cell seal member 2 is transported by the transport device 8 from a mold (not shown) to the upper concave portion 41U of the storage tray 4. Next, the cell seal member 2 is disposed in the upper concave portion 41 </ b> U of the storage tray 4. Note that the upper surface of the cell seal member 2 is sucked by the suction nozzle 80 of the transport device 8 during transport and placement.
　図７に示すように、積層ステップにおいては、全ての収納用トレイ４を、上下方向に積層させる。すなわち、図４に示すように、下側トレイ４Ｄと上側トレイ４Ｕとの間に、収容部Ａ、係合部Ｂ、隙間Ｃを形成する。また、全ての収納用トレイ４の貫通孔４３を、上下方向に連結させる。このようにして、図４に示すように、所定の段数（例えば６段）のトレイ積層体Ｓを作成する。 As shown in FIG. 7, in the stacking step, all the storage trays 4 are stacked in the vertical direction. That is, as shown in FIG. 4, the accommodating part A, the engaging part B, and the clearance C are formed between the lower tray 4D and the upper tray 4U. Further, the through holes 43 of all the storage trays 4 are connected in the vertical direction. In this way, as shown in FIG. 4, a tray stack S having a predetermined number of stages (for example, six stages) is created.
　［積層体搬送工程］
　本工程においては、例えば車両、電車、船舶、飛行機などにより、トレイ積層体Ｓを搬送する。すなわち、複数の収納用トレイ４（つまり複数のセルシール部材２）を、トレイ積層体Ｓの状態で、まとめて搬送する。 [Laminated body transport process]
In this step, the tray stack S is conveyed by, for example, a vehicle, a train, a ship, an airplane, or the like. That is, a plurality of storage trays 4 (that is, a plurality of cell seal members 2) are transported together in the state of the tray stack S.
　＜作用効果＞
　次に、本実施形態の収納用トレイの作用効果について説明する。図５に示すように、収容部Ａに収容されたセルシール部材２と、上側トレイ４Ｕと、の間には隙間が確保されている。このため、トレイ積層工程、積層体搬送工程において、セルシール部材２に荷重が加わりにくい。 <Effect>
Next, the function and effect of the storage tray of this embodiment will be described. As shown in FIG. 5, a gap is secured between the cell seal member 2 accommodated in the accommodating portion A and the upper tray 4U. For this reason, it is difficult to apply a load to the cell seal member 2 in the tray stacking process and the stacked body transporting process.
　また、図３に示すように、上側凹部４１Ｕ（つまり収容部Ａ）は、セルシール部材２と型対称の無端環状かつ四角形枠状を呈している。このため、トレイ積層工程、積層体搬送工程において、セルシール部材２が、捩れたり絡んだりしにくい。すなわち、セルシール部材２が変形しにくい。したがって、セルシール部材２が、燃料電池９において実際に使用される形状、つまりシール形状を維持しやすい。 Further, as shown in FIG. 3, the upper concave portion 41U (that is, the accommodating portion A) has an endless annular and quadrangular frame shape that is type-symmetric with the cell seal member 2. For this reason, the cell seal member 2 is not easily twisted or entangled in the tray stacking process and the stacked body transporting process. That is, the cell seal member 2 is not easily deformed. Therefore, the cell seal member 2 can easily maintain the shape actually used in the fuel cell 9, that is, the seal shape.
　また、図４に示すように、積層体搬送工程において、複数（上記実施形態では６段）の収納用トレイ４、つまり複数（上記実施形態では５枚）のセルシール部材２を、トレイ積層体Ｓの状態で、まとめて搬送することができる。このため、搬送効率が高い。 In addition, as shown in FIG. 4, in the stacked body transporting step, a plurality of (six in the above embodiment) storage trays 4, that is, a plurality of (in the above embodiment, five) cell seal members 2 are connected to the tray stacked body S. In this state, they can be transported together. For this reason, conveyance efficiency is high.
　また、図５に示すように、収容部Ａは、下側トレイ４Ｄの上側凹部４１Ｕと、上側トレイ４Ｕの下側凹部４１Ｄと、の間に区画されている。このため、下側トレイ４Ｄに上側トレイ４Ｕを積層させることにより、収容部Ａを形成することができる。 Further, as shown in FIG. 5, the accommodating portion A is partitioned between the upper concave portion 41U of the lower tray 4D and the lower concave portion 41D of the upper tray 4U. For this reason, the accommodating part A can be formed by stacking the upper tray 4U on the lower tray 4D.
　また、図５に示すように、上下方向長さＥ、上下方向厚みＦは、セルシール部材２の横断面における水平方向幅Ｗ（収容部Ａの水平方向幅）よりも、小さい。このため、収容部Ａにおいて、セルシール部材２は、変形しにくい。 Further, as shown in FIG. 5, the vertical length E and the vertical thickness F are smaller than the horizontal width W (horizontal width of the accommodating portion A) in the cross section of the cell seal member 2. For this reason, in the accommodating part A, the cell seal member 2 is not easily deformed.
　また、図４に示すように、積層体搬送工程において、セルシール部材２が配置されていない最上段の収納用トレイ４は、トレイ積層体Ｓの蓋として機能する。このため、トレイ積層体Ｓの内部に、上側から塵埃が侵入するのを、抑制することができる。 Further, as shown in FIG. 4, the uppermost storage tray 4 on which the cell seal member 2 is not disposed functions as a lid of the tray stack S in the stack transport process. For this reason, it can suppress that a dust penetrate | invades into the inside of the tray laminated body S from an upper side.
　また、図３に示すように、基部４０の外周部４００の水平方向外側には、位置決め部４２が配置されている。図４に示すように、下側トレイ４Ｄと上側トレイ４Ｕとの間には、下側トレイ４Ｄの位置決め部４２と、上側トレイ４Ｕの位置決め部４２と、が互いに係合することにより、係合部Ｂが設定されている。係合部Ｂは、下側トレイ４Ｄと上側トレイ４Ｕとの相対的な水平方向のずれを抑制している。このため、搬送時に、トレイ積層体Ｓが分解しにくい。一方、係合部Ｂは、下側トレイ４Ｄと上側トレイ４Ｕとの相対的な上下方向の移動を許容している。このため、トレイ積層工程においては、下側トレイ４Ｄに上側トレイ４Ｕを簡単に積み重ねることができる。 Further, as shown in FIG. 3, a positioning portion 42 is disposed outside the outer peripheral portion 400 of the base portion 40 in the horizontal direction. As shown in FIG. 4, the positioning unit 42 of the lower tray 4D and the positioning unit 42 of the upper tray 4U are engaged with each other between the lower tray 4D and the upper tray 4U. Part B is set. The engaging portion B suppresses a relative horizontal shift between the lower tray 4D and the upper tray 4U. For this reason, at the time of conveyance, the tray stack S is not easily decomposed. On the other hand, the engaging part B allows the relative vertical movement of the lower tray 4D and the upper tray 4U. For this reason, in the tray stacking step, the upper tray 4U can be easily stacked on the lower tray 4D.
　また、図４に示すように、下側トレイ４Ｄと上側トレイ４Ｕとの間には、上下方向の隙間Ｃが確保されている。すなわち、下側トレイ４Ｄの位置決め部４２と、上側トレイ４Ｕの位置決め部４２と、は当接しているものの、それ以外の部位では、下側トレイ４Ｄと上側トレイ４Ｕとは当接していない。このため、搬送時に、下側トレイ４Ｄと上側トレイ４Ｕとが摺接しにくい。したがって、下側トレイ４Ｄと上側トレイ４Ｕとの間から塵埃（例えば、摩耗粉、摩耗片、バリ、カスなど）が発生しにくい。 Further, as shown in FIG. 4, a vertical gap C is secured between the lower tray 4D and the upper tray 4U. That is, the positioning portion 42 of the lower tray 4D and the positioning portion 42 of the upper tray 4U are in contact with each other, but the lower tray 4D and the upper tray 4U are not in contact with other portions. For this reason, it is difficult for the lower tray 4D and the upper tray 4U to come into sliding contact during conveyance. Accordingly, dust (for example, wear powder, wear pieces, burrs, debris, etc.) is not easily generated from between the lower tray 4D and the upper tray 4U.
　ただし、図４に示すように、係合部Ｂにおいては、下側トレイ４Ｄの位置決め部４２と、上側トレイ４Ｕの位置決め部４２と、が当接している。このため、位置決め部４２同士の摺接により、係合部Ｂから塵埃が発生することも考えられる。この点、位置決め部４２と基部４０の外周部４００との間、つまり係合部Ｂと収容部Ａとの間には、貫通孔４３が配置されている。このため、係合部Ｂで発生した塵埃を、貫通孔４３に落下させることができる。したがって、係合部Ｂで発生した塵埃が収容部Ａに到達するのを、抑制することができる。 However, as shown in FIG. 4, in the engaging portion B, the positioning portion 42 of the lower tray 4D and the positioning portion 42 of the upper tray 4U are in contact with each other. For this reason, it is also conceivable that dust is generated from the engaging portion B due to the sliding contact between the positioning portions 42. In this respect, a through hole 43 is disposed between the positioning portion 42 and the outer peripheral portion 400 of the base portion 40, that is, between the engaging portion B and the accommodating portion A. For this reason, dust generated in the engaging portion B can be dropped into the through hole 43. Therefore, it is possible to suppress the dust generated in the engaging portion B from reaching the housing portion A.
　また、収納用トレイ４は、帯電防止材料製である。このため、塵埃が収納用トレイ４に付着しにくい。この点においても、係合部Ｂで発生した塵埃が収容部Ａに到達するのを、抑制することができる。 The storage tray 4 is made of an antistatic material. For this reason, it is difficult for dust to adhere to the storage tray 4. Also in this point, it is possible to suppress the dust generated in the engaging portion B from reaching the housing portion A.
　また、隙間Ｃのため、下側トレイ４Ｄの上側凹部４１Ｕの開口縁と、上側トレイ４Ｕの下側凹部４１Ｄの開口縁と、は当接していない。このため、セルシール部材２のシール本体２０の内周面や外周面が、開口縁間に挟み込まれるおそれが小さい。 Also, because of the gap C, the opening edge of the upper recess 41U of the lower tray 4D and the opening edge of the lower recess 41D of the upper tray 4U are not in contact. For this reason, there is little possibility that the inner peripheral surface and outer peripheral surface of the seal main body 20 of the cell seal member 2 are sandwiched between the opening edges.
　また、図６に示すように、トレイ積層工程において、吸着ノズル８０の下面は、セルシール部材２の上面よりも、大きい。このため、搬送の際、吸着ノズル８０の下面は、セルシール部材２の上面から、水平方向にはみ出している。 Further, as shown in FIG. 6, the lower surface of the suction nozzle 80 is larger than the upper surface of the cell seal member 2 in the tray stacking process. For this reason, the lower surface of the suction nozzle 80 protrudes from the upper surface of the cell seal member 2 in the horizontal direction during conveyance.
　ここで、仮に、上側凹部４１Ｕの上下方向長さＧが、セルシール部材２の上下方向厚みＦよりも、大きい場合を想定する。この場合、セルシール部材２を上側凹部４１Ｕに配置する際、セルシール部材２の下面が上側凹部４１Ｕの底面に当接するよりも早く、吸着ノズル８０の下面が収納用トレイ４の基部４０の上面に当接してしまう。このため、宙吊り状態のセルシール部材２を、上側凹部４１Ｕの底面に、落下させることになる。したがって、収納用トレイ４に対するセルシール部材２の位置決め精度が低下してしまう。 Here, it is assumed that the vertical length G of the upper concave portion 41U is larger than the vertical thickness F of the cell seal member 2. In this case, when the cell seal member 2 is disposed in the upper recess 41U, the lower surface of the suction nozzle 80 contacts the upper surface of the base 40 of the storage tray 4 faster than the lower surface of the cell seal member 2 contacts the bottom surface of the upper recess 41U. It touches. For this reason, the suspended cell seal member 2 is dropped onto the bottom surface of the upper concave portion 41U. Therefore, the positioning accuracy of the cell seal member 2 with respect to the storage tray 4 is lowered.
　この点、本実施形態の収納用トレイ４の場合、上側凹部４１Ｕの上下方向長さＧが、セルシール部材２の上下方向厚みＦよりも、小さい。このため、セルシール部材２を上側凹部４１Ｕに配置する際、吸着ノズル８０の下面が収納用トレイ４の基部４０の上面に当接するよりも早く、セルシール部材２の下面が上側凹部４１Ｕの底面に当接する。したがって、セルシール部材２を、しっかりと上側凹部４１Ｕに配置することができる。よって、収納用トレイ４に対するセルシール部材２の位置決め精度が高くなる。 In this regard, in the case of the storage tray 4 of the present embodiment, the vertical length G of the upper concave portion 41U is smaller than the vertical thickness F of the cell seal member 2. For this reason, when the cell seal member 2 is disposed in the upper recess 41U, the lower surface of the cell seal member 2 contacts the bottom surface of the upper recess 41U faster than the lower surface of the suction nozzle 80 contacts the upper surface of the base 40 of the storage tray 4. Touch. Therefore, the cell seal member 2 can be firmly disposed in the upper concave portion 41U. Therefore, the positioning accuracy of the cell seal member 2 with respect to the storage tray 4 is increased.
　また、セルシール部材２は、芯材なしのゴムの単体成形品（一体物）である。このため、柔軟性が高い。また、図５に示すように、セルシール部材２の横断面における水平方向幅Ｗは、上下方向厚みＦよりも、大きい。すなわち、横断面のアスペクト比（Ｗ／Ｆ）は、１より大きい。つまり、セルシール部材２は薄型、軽量である。このような柔軟、薄型、軽量なセルシール部材２であっても、本実施形態の収納用トレイ４によると、トレイ積層工程、積層体搬送工程において、セルシール部材２に荷重が加わりにくい。また、セルシール部材２が変形しにくい。 Further, the cell seal member 2 is a single-piece molded product (integral product) of rubber without a core material. For this reason, flexibility is high. As shown in FIG. 5, the horizontal width W in the cross section of the cell seal member 2 is larger than the vertical thickness F. That is, the aspect ratio (W / F) of the cross section is greater than 1. That is, the cell seal member 2 is thin and lightweight. Even with such a flexible, thin, and lightweight cell seal member 2, according to the storage tray 4 of the present embodiment, it is difficult for a load to be applied to the cell seal member 2 in the tray stacking process and the stacked body transporting process. Further, the cell seal member 2 is not easily deformed.
　＜その他＞
　以上、本発明のシール部材収納用トレイの実施の形態について説明した。しかしながら、実施の形態は上記形態に特に限定されるものではない。当業者が行いうる種々の変形的形態、改良的形態で実施することも可能である。 <Others>
The embodiment of the seal member storage tray of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.
　図８に、その他の実施形態の複数の収納用トレイの積層体であるトレイ積層体の上下方向部分断面図を示す。なお、図４と対応する部位については、同じ符号で示す。 FIG. 8 shows a partial sectional view in the vertical direction of a tray laminate that is a laminate of a plurality of storage trays according to another embodiment. In addition, about the site | part corresponding to FIG. 4, it shows with the same code | symbol.
　図８に示すように、収納用トレイ４に上側凹部４１Ｕだけを配置してもよい。そして、下側トレイ４Ｄの上側凹部４１Ｕと、上側トレイ４Ｕの基部４０の下面と、により収容部Ａを区画してもよい。 As shown in FIG. 8, only the upper recess 41U may be arranged in the storage tray 4. Then, the accommodating portion A may be partitioned by the upper concave portion 41U of the lower tray 4D and the lower surface of the base portion 40 of the upper tray 4U.
　また、図８に示すように、積層体搬送工程においてトレイ積層体Ｓを搬送後、トレイ積層体Ｓを上下反転させてもよい。こうすると、収納用トレイ４（旧上側トレイ４Ｕ）の基部４０の上面（旧下面）に、セルシール部材２が載置されている状態になる。このため、簡単にセルシール部材２を取り出すことができる。なお、セルシール部材２のシール本体２０の下面（図８に示す状態に対して、上下反転状態における下面）には、シールリップ２１が配置されていない。シール本体２０の下面は、図２に示すセパレータ９３の上面に接着される。 Further, as shown in FIG. 8, after transporting the tray stack S in the stack transport step, the tray stack S may be turned upside down. As a result, the cell seal member 2 is placed on the upper surface (old lower surface) of the base 40 of the storage tray 4 (old upper tray 4U). For this reason, the cell seal member 2 can be easily taken out. Note that the seal lip 21 is not disposed on the lower surface of the seal body 20 of the cell seal member 2 (the lower surface in the upside down state with respect to the state shown in FIG. 8). The lower surface of the seal body 20 is bonded to the upper surface of the separator 93 shown in FIG.
　図６、図７に示すトレイ積層工程における、セルシール部材２を収納用トレイ４の上側凹部４１Ｕに配置する配置ステップと、収納用トレイ４を積層させる積層ステップと、の前後関係は特に限定しない。配置ステップと積層ステップとを同時並行的に実行してもよい。すなわち、まず、最下段の収納用トレイ４の上側凹部４１Ｕにセルシール部材２を配置し、次に、その上から別の収納用トレイ４を積層させ、続いて、下から二段目の収納用トレイ４の上側凹部４１Ｕにセルシール部材２を配置し、さらに、その上から別の収納用トレイ４を積層させてもよい（以下同様）。 In the tray stacking process shown in FIG. 6 and FIG. 7, the front-rear relationship between the placement step of placing the cell seal member 2 in the upper concave portion 41U of the storage tray 4 and the stacking step of stacking the storage tray 4 is not particularly limited. The placement step and the stacking step may be performed simultaneously. That is, first, the cell seal member 2 is disposed in the upper concave portion 41U of the lowermost storage tray 4, and then another storage tray 4 is stacked from above, followed by the second storage from the bottom. The cell seal member 2 may be disposed in the upper concave portion 41U of the tray 4, and another storage tray 4 may be stacked thereon (the same applies hereinafter).
　図２に示すセルシール部材２のシール本体２０の枠部の形状、位置、配置数は特に限定しない。図３に示す収納用トレイ４の用途は特に限定しない。例えば、セルシール部材２の搬送用、仮置き用、保存用、検査用であってもよい。 The shape, position, and arrangement number of the frame portion of the seal body 20 of the cell seal member 2 shown in FIG. 2 are not particularly limited. The use of the storage tray 4 shown in FIG. 3 is not particularly limited. For example, the cell seal member 2 may be used for transportation, temporary placement, storage, or inspection.
　図３に示す単一の収納用トレイ４に、水平方向に複数のセルシール部材２を並置してもよい。こうすると、さらに多数の収納用トレイ４、つまりセルシール部材２を、トレイ積層体Ｓの状態で、まとめて搬送することができる。このため、搬送効率が高い。 A plurality of cell seal members 2 may be juxtaposed in the horizontal direction on a single storage tray 4 shown in FIG. In this way, a larger number of storage trays 4, that is, the cell seal members 2, can be transported together in the state of the tray stack S. For this reason, conveyance efficiency is high.
　図４に示すトレイ積層体Ｓにおける収納用トレイ４の段数（配置数）は特に限定しない。また、トレイ積層体Ｓに収容されるセルシール部材２の配置数も特に限定しない。 The number of storage trays 4 in the tray stack S shown in FIG. Further, the number of cell seal members 2 accommodated in the tray stack S is not particularly limited.
　セルシール部材２の材質は特に限定しない。ゴム成分の他に、架橋剤、架橋助剤、接着成分などを含んでいてもよい。好適なゴム成分としては、ＥＰＤＭの他、シリコーンゴム（ＶＭＱ）、フッ素ゴム（ＦＫＭ）、ブチルゴム（ＩＩＲ）、エチレン－プロピレンゴム（ＥＰＭ）、アクリロニトリル－ブタジエンゴム（ＮＢＲ）、水素添加アクリロニトリル－ブタジエンゴム（Ｈ－ＮＢＲ）、スチレン－ブタジエンゴム（ＳＢＲ）、ブタジエンゴム（ＢＲ）などが挙げられる。 The material of the cell seal member 2 is not particularly limited. In addition to the rubber component, a crosslinking agent, a crosslinking aid, an adhesive component, and the like may be included. Suitable rubber components include EPDM, silicone rubber (VMQ), fluorine rubber (FKM), butyl rubber (IIR), ethylene-propylene rubber (EPM), acrylonitrile-butadiene rubber (NBR), hydrogenated acrylonitrile-butadiene rubber.
