Patent number: 8828620Abstract: Fabricating roll-good fuel cell material involves laminating first and second bonding material webs having spaced apart windows to first and second surfaces of a fuel cell membrane web. First and second active regions of the membrane web are positioned within the respective bonding material windows. Third and fourth gasket material webs having spaced apart windows are respectively laminated to the bonding material on the first and second membrane web surfaces. The bonding material windows align with the respective gasket material windows so that at least some of the bonding material extends within the respective gasket material windows. Fluid transport layer (FTL) material portions cut from fifth and sixth FTL material webs are laminated to the respective first and second active regions. The FTL material portions are positioned within respective gasket material windows and contact the bonding material extending within the respective gasket material windows.Type: GrantFiled: August 30, 2012Date of Patent: September 9, 2014Assignee: 3M Innovative Properties CompanyInventors: David Robert Mekala, Donald George Peterson, Dennis Earl Ferguson, Duane Douglas Fansler

Patent number: 8124169Abstract: An antimicrobial coating system, a film-forming composition, and an antimicrobial film. In some embodiments, the antimicrobial coating system can include a film-forming composition comprising a polymer having an effective molecular weight, and an effective amount of an antimicrobial agent dispersed within the polymer. The film-forming composition can form a water-insoluble, biocidal antimicrobial film when applied to a surface.Type: GrantFiled: December 14, 2006Date of Patent: February 28, 2012Assignee: 3M Innovative Properties CompanyInventors: Caroline M. Ylitalo, Gerald R. A. Hofmann, Mitchell T. Johnson, Linda K. M. Olson, Duane Douglas Fansler
