Patent number: 10164285Abstract: A sub-assembly for an electrochemical stack, such as a PEM fuel cell stack, has a bipolar plate with sealing material extending from its upper face, around the edge of the bipolar plate, and onto its lower face. The bipolar plate is preferably a combination of an anode plate and a cathode plate defining an internal coolant flow field and bonded together by sealing material which also provides a seal around the coolant flow field. All of the sealing material in the sub-assembly may be one contiguous mass. To make the sub-assembly, anode and cathode plates are loaded into a mold. Liquid sealing material is injected into the mold and fills a gap between the edge of the plates, and portions of the outer faces of the plates, and the mold. In a stack, sub-assemblies are separated by MEAs which at least partially overlap the sealing material on their faces.Type: GrantFiled: October 1, 2014Date of Patent: December 25, 2018Assignee: HYDROGENICS CORPORATIONInventor: David Frank

Patent number: 10096860Abstract: This invention provides a method of manufacturing a nonaqueous electrolyte secondary batteries which includes placing an electrode assembly in a hermetically sealable battery case, injecting a nonaqueous electrolyte into the battery case after the battery case has been set in a pressure-reduced state, and sealing the battery case under atmospheric pressure conditions. Sealing of the battery case is carried out before a given amount of the injected electrolyte completely impregnates the interior of the electrode assembly. As a result, the remaining nonaqueous electrolyte impregnates the interior of the electrode assembly after sealing, thereby making the pressure of voids within the battery case lower than atmospheric pressure.Type: GrantFiled: October 21, 2014Date of Patent: October 9, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Tomohiko Ishida
