| 20120131793 | METHOD FOR MANUFACTURING A GASKET - A gasket for a bipolar battery comprises a structural part in the shape of a frame having an upper surface and a lower surface, and at least one channel to permit gas passage through the gasket. The structural part may be made from a first material having hydrophobic properties. The gasket further comprises at least a first sealing surface arranged in a closed loop projecting from the upper surface, and at least a second sealing surface arranged in a closed loop projecting from the lower surface. The first and the second sealing surfaces are provided on at least one sealing part, are made from a second material, and the first material of the structural part has a higher elastic modulus than an elastic modulus of the second material of the sealing parts. A bipolar battery and a method for manufacturing a gasket are also disclosed. | 05-31-2012 |
