Patent number: 8153316Abstract: A stackable unitized fuel cell system includes a cooling capability. A unitized fuel cell system includes a unitized fuel cell assembly having a first flow field plate, a second flow field plate, and a membrane electrode assembly (MEA) provided between the first and second flow field plates. In one configuration, a cooling structure is separable with respect to the unitized fuel cell assembly. In another configuration, the cooling structure is integral to the unitized fuel cell assembly. A retention arrangement is provided on one or both of the unitized fuel cell assembly and cooling structure. The retention arrangement is configured to facilitate mating engagement between the unitized fuel cell assembly, the cooling structure, and adjacent unitized fuel cell systems of a fuel cell stack.Type: GrantFiled: November 15, 2002Date of Patent: April 10, 2012Assignee: 3M Innovative Properties CompanyInventors: Daniel M.

Patent number: 8012284Abstract: Fabrication methods for making a gas diffusion layer incorporating a gasket (GIG) fuel cell subassemblies via roll-to-roll processes are described. A material processable by one or both of heat and pressure having spaced apart apertures is transported to a bonding station. A first gasket layer having gas diffusion layers arranged in relation to spaced apart apertures of a first gasket layer is transported to the bonding station. The heat/pressure processable material is aligned with the first gasket layer and the gas diffusion layers. At the bonding station, the heat/pressure processable material is bonded to the first gasket layer and the gas diffusion layers. After bonding, the heat/pressure processable material forms a second gasket layer that attaches the gas diffusion layers to the first gasket layer.Type: GrantFiled: December 15, 2006Date of Patent: September 6, 2011Assignee: 3M Innovative Properties CompanyInventors: Mark K. Debe, Andrew J. L. Steinbach, Jimmy M. Le, Stephan J. Obradovich, Eric J. Iverson
