Description

このようなシール対象物としては、積層型燃料電池の構成部品である多孔質カーボン電極板、高分子固体電解質膜、セパレータ、冷却板、モジュール、マニホールド等が挙げられ、好ましくは多孔質カーボン電極に適用される。そして、電極面方向では、材料の座屈強度以下の接触面圧でシールすることが可能となる。また、加硫性シール材料がシール対象物のシール部の空隙部分に入り込んだ状態で加硫が行われているので、物理的に完全なる接着が行われており、従来のシールが接触面圧でシールしなければならなかったために生じた電極の座屈破壊やシール材の厚肉化の問題もなく、燃料電池ユニットの製造が容易となる。 Examples of such sealing objects include porous carbon electrode plates, polymer solid electrolyte membranes, separators, cooling plates, modules, manifolds, and the like, which are constituent parts of stacked fuel cells. Applied. In the electrode surface direction, sealing can be performed with a contact surface pressure equal to or lower than the buckling strength of the material. In addition, since vulcanization is performed in a state where the vulcanizable sealing material enters the gap portion of the seal portion of the object to be sealed, physical perfect adhesion is performed, and the conventional seal has a contact surface pressure. Thus, there is no problem of electrode buckling breakage and thickening of the sealing material, which are caused by having to be sealed, and the manufacture of the fuel cell unit is facilitated.

加硫性シール材料は、空隙部を有するシール対象物と一体化、好ましくは加硫一体化してガスケットを形成させる。 The vulcanizable sealing material is integrated with a sealing object having a void portion, preferably vulcanized and integrated to form a gasket.

Claims (2)

加硫性シール材料を含浸させた延伸多孔質PTFEシートと多孔質カーボンシートとを加硫一体化させた積層型燃料電池用シール材。 A laminated fuel cell sealing material in which an expanded porous PTFE sheet impregnated with a vulcanizable sealing material and a porous carbon sheet are vulcanized and integrated. 空隙部を有するシール対象物にシール材料を所定のシール材厚みになるようにコーティングした後、または空隙部を有するシール対象物をインサートした金型内に加硫性シール材料を注入した後、圧縮成形、トランスファー成形または射出成形することにより加硫一体化させることを特徴とする積層型燃料電池用ガスケットの製造法。 Compression is applied after coating the sealing material with a predetermined sealant thickness on the object to be sealed having voids, or after injecting the vulcanizable sealing material into a mold in which the object to be sealed having voids is inserted. A method for producing a gasket for a laminated fuel cell, wherein the vulcanization is integrated by molding, transfer molding or injection molding.
