Description

基材としては、それが燃料電池のセパレータである場合、カーボン、金属材等のヤング率(縦弾性係数；物体に単純な張力が働いたとき、その応力の強さを歪で割った値であり、一軸引張試験により測定)が10GPa以上となるが、ガスケットとして用いられるゴム材のヤング率は約1〜10MPa程度である。ゴム製のガスケットは、一般にシート状加硫ゴムまたはそこに任意形状のリップ部を形成させたものであり、そのゴム材料としては、例えばEPDM、フッ素ゴム等が用いられるが、耐酸性、耐不凍液性、低温特性等の点からはフッ素ゴムが好んで用いられる。 As a base material, when it is a separator of a fuel cell, Young's modulus (longitudinal elastic modulus; when a simple tension is applied to an object, the value of the stress divided by the strain Yes, measured by a uniaxial tensile test) is 10 GPa or more, but the Young's modulus of a rubber material used as a gasket is about 1 to 10 MPa. A rubber gasket is generally a sheet-like vulcanized rubber or a lip portion having an arbitrary shape formed thereon. As the rubber material, for example, EPDM, fluororubber, etc. are used. From the viewpoints of properties and low-temperature characteristics, fluororubber is preferably used.
