【課題を解決するための手段】上記課題を解決するために、本発明によればりん酸電解質を有する単電池を積層してなる電池積層体の側面に取付けられ、電池積層体から排出される反応ガスが集流される室を形成するマニホールド側板と、この側板に取付けられるノズルとからなり、内面に耐食性及び絶縁性を有する被覆層を設けたりん酸型燃料電池の反応ガス用マニホールドにおいて、一方の端部にフランジを備え、両端面に開口する流路孔を有し、耐食性及び絶縁性を有するブッシュをフランジとマニホールド側板の被覆層との間に間隙を持たせて前記ノズルに装着するものとする。 Means for Solving the Problems] To solve the above problem, mounted on the side of the cell stack formed by stacking single cells with phosphate electrolyte according to the present invention, is discharged from the cell stack a manifold plate of the reaction gas to form a current flowed chamber consists of a nozzle attached to the side plates, in the reaction gas manifold of the corrosion resistance and phosphoric acid fuel cell provided with a coating layer having an insulating property on the inner surface, whereas that end provided with a flange having a flow passage holes opening to both end surfaces, the bushing having corrosion resistance and insulating property by providing a gap between the covering layer of the flange and the manifold plate is attached to the nozzle to.

【0009】前記ブッシュはノズルに装着可能な装着部と、この装着部から段をなして太くなり、この段面を取付座とする取付部と、取付座から離れた取付部の個所から突出するフランジと、装着部と取付部の端面に開口する流路孔とからなり、耐食性及び絶縁性を有して構成し、このブッシュを、その取付座をマニホールド側板の被覆層に接し、装着部をノズルに装着してマニホールドに取付けるものとする。 [0009] and the bush can be mounted portion mounted on the nozzle, thickens and forms a stepped from the mounting portion, the mounting portion for the step surface and the mounting seat, protruding from the location of the mounting portion away from the mounting seat and the flange consists of a opening to the flow passage bore in the end face of the mounting portion and the mounting portion, and configured to have a corrosion resistance and insulating properties, this bush in contact with the mounting seat for the coating layer of the manifold plate, the mounting portion and attached to the nozzle shall be attached to the manifold.

【0010】また、前記ブッシュの取付座に流路孔を囲む環状の溝を設け、この溝に挿入される耐食性及び絶縁性を有するガスケットを介してブッシュを、その取付座をマニホールド側板の被覆層に接し、その装着部をノズルに装着してマニホールドに取付けるものとする。 Further, the annular groove surrounding the passage hole in the mounting seat of the bushing is provided, the bush via a gasket having corrosion resistance and insulating property is inserted into the groove, the covering layer of the manifold plate and the mounting seat in contact shall be attached to the manifold by mounting the mounting portion on the nozzle.

【0011】 [0011]

【作用】一方の端部にフランジを備え、両端面に開口する流路孔を有し、耐食性及び絶縁性を有するブッシュをノズルに装着する際、フランジとマニホールド側板の耐食性及び絶縁性を有する被覆層との間に間隙を持たせる。 [Action] comprises a flange at one end, has a flow path holes opening on both end surfaces, when mounting the bushing having corrosion resistance and insulating properties in a nozzle, the coating having corrosion resistance and insulating flange and the manifold plate to have a gap between the layers. この際、ブッシュをノズルに装着する装着部と、この装着部から段をなして太くなり、この段面を取付座とする取付部と、取付座から離れた個所から突出するフランジと、装着部と取付部との端面に開口する流路孔とからなり、耐食性及び絶縁性を有して構成し、このブッシュをその取付部の取付座をマニホールド側板に設けられた耐食性及び絶縁性を有する被覆層に接し、その装着部をノズルに装着してマニホールドに取付けることにより、フランジが取付座から離れた個所から突出しているので、フランジとマニホールド側板の被覆層との間は間隙を有している。 In this case, a mounting portion for mounting the bushing to the nozzle, thickens and forms a stepped from the mounting portion, the mounting portion for the step surface and the mounting seat, a flange projecting from a location remote from the mounting seat, the mounting portion and consists of a opening to the flow passage bore in the end face of the mounting portion, and configured to have a corrosion resistance and insulation properties, the bushing coatings with corrosion resistance and insulating property is provided a mounting seat for the mounting portion in the manifold plate contact with the layer, by mounting the manifold by mounting the mounting portion on the nozzle, since a flange is protruded from the location away from the mounting seat, between the covering layer of the flange and the manifold plate have a gap .

【0012】ところで、電池積層体の各単電池から排出される反応ガスはマニホールド側板で形成される室に集流された後ノズルを通って外部に排出される。 By the way, the reaction gas discharged from the unit cells of the cell stack is discharged to the outside through the nozzle after the shed collecting in chamber formed in the manifold plate. この際ブッシュのフランジとマニホールド側板の被覆層との間の間隙はデッドスペースとなり、反応ガスが流れ込まなくなる。 The gap between the coating layer of the flange and the manifold plate of this time bushing becomes dead space, the reaction gas can not flow into. したがって排出される反応ガス中のりん酸ミスト等が付着しないので、ノズル取付角部付近に被覆層の欠陥があっても絶縁性,耐食性の低下を起さない。 Hence phosphate mist in the reaction gas discharged does not adhere, insulation even when defects of the coating layer in the vicinity of the nozzle mounting angle portion, without causing deterioration of corrosion resistance. したがってマニホールド内面に設ける被覆層はその平坦部で欠陥の生じない必要最小限度の厚さでよくなる。 Thus the coating layer provided on the manifold inner surface, the better a thickness of necessary minimum as not to generate defect in the flat portion.

【0013】またノズルがマニホールド側板の最下部に取付けられる場合には、ブッシュの取付座に設けられた環状の溝に耐食性及び絶縁性を有するガスケットを挿入して前述のようにブッシュをその取付座をマニホールド側板の被覆層に接し、装着部をノズルに装着してマニホールドに取付けることより、りん酸ミストや水のドレンが最下部のブッシュのフランジとマニホールド側板の被覆層との間の間隙に流れ込んでもガスケットによりノズル取付角部付近には流れ込まないので、ノズル取付角部付近に被覆層の欠陥があっても絶縁性,耐食性の低下を起さない。 [0013] When the nozzle is attached to the bottom of the manifold plate, the mounting seat of the bushing as described above by inserting the gasket having a corrosion resistance and insulating property annular groove provided in the mounting seat of the bushing the contact with the coating layer of the manifold plate, from attaching to the manifold by mounting the mounting portion on the nozzle, flows into the gap between the drain phosphate mist or water to the coating layer of the flange and the manifold plate of the bottom of the bushing But since no flow into the vicinity of the nozzle mounting angle section by a gasket, insulating resistance even if there is a defect of the coating layer in the vicinity of the nozzle mounting angle portion, without causing deterioration of corrosion resistance.
