Patent number: 9065158Abstract: A cooling module for a battery pack assembly is disclosed. The cooling module includes a frame having a plurality of legs forming an opening through a central portion of the frame, at least one of the plurality of legs including a slot formed therethrough. A cooling fin is coupled to the frame. The cooling fin includes a corrugated plate interposed between a first plate and a second plate forming a plurality of fluid flow channels between the first plate and the second plate. The cooling modules are disposed in a stack having at least one battery cell disposed between adjacent cooling modules. The battery cell is in heat transfer communication with the cooling fin of at least one cooling module, wherein the cooling fin facilitates a transfer of heat energy between the battery cell and the flow channels formed in the cooling fin.Type: GrantFiled: May 28, 2010Date of Patent: June 23, 2015Assignee: GM Global Technology Operations LLCInventors: William L. Martz, Michael Duffield, Megan J. Quick, Stuart D. Barter, Glenn W. Skala, Steven J. Fogarassy, Eric J. Connor, Thaddeus J. Grey

Publication number: 20140306359Abstract: A fuel cell humidifier with a pleated separation layer between a wet side and a dry side is provided. The fuel cell humidifier includes an enclosure having a first inlet, first outlet, and a first gas flow region that allow flow of a first gas through the humidifier. The fuel cell humidifier also includes a second inlet and second outlet, and a second gas flow region that allow flow of a second gas through the humidifier. Characteristically, the first gas has a higher relative humidity than the second gas. A pleated diffusion medium separates the first flow region and the second flow region such that water from the first gas flows to the second gas thereby increasing the relative humidity of the second gas.Type: ApplicationFiled: April 15, 2013Publication date: October 16, 2014Applicant: GM Global Technology Operations LLCInventor: William L. Martz
