摘要： A membrane electrode assembly comprises an edge seal member, the edge seal member having a first compressive surface and an opposing second compressive surface wherein the first compressive surface comprises a seal protrusion and the opposing second compressive comprises an inner and outer seal protrusion. The seal protrusion on the first compressive surface is positioned asymmetrically in relation to the inner and outer seal protrusions on the second compressive surface such that the centerline of the seal protrusion on the first compressive surface is positioned between the centerline of the inner seal protrusion and the centerline of the outer seal protrusion on the second compressive surface. The seal protrusions may be shaped such that the base is wide and narrows toward a contacting end thereof, wherein the contacting end is in contact with a surface of a flow field plate. The geometry and positions of the seal protrusions can be adjusted to optimize the contact pressure on the edge seal member and contacting points thereof.
摘要翻译：膜电极组件包括边缘密封构件，边缘密封构件具有第一压缩表面和相对的第二压缩表面，其中第一压缩表面包括密封突起，并且相对的第二压缩包括内部和外部密封突出部。第一压缩表面上的密封突起相对于第二压缩表面上的内密封突起和外密封突起不对称地定位，使得第一压缩表面上的密封突起的中心线位于内密封突起的中心线和第二压缩表面上的外部密封突起的中心线。密封突起可以成形为使得基部朝向其接触端宽而窄，其中接触端与流场板的表面接触。可以调节密封突起的几何形状和位置，以优化边缘密封件及其接触点的接触压力。
