Patent number: 8114554Abstract: An arrangement for a direct methanol fuel cell includes a fuel cartridge that supplies a source of fuel to the direct methanol fuel cell. The fuel cartridge has a surface area enhanced planar vaporization membrane residing in the fuel cartridge. The arrangement also includes a fuel reservoir that receives fuel from the fuel cartridge, the fuel reservoir arranged to deliver fuel to the fuel cell. The fuel reservoir also including a surface area enhanced planar vaporization membrane residing in the fuel reservoir. The combination of the surface area enhanced planar vaporization membranes residing in the fuel cartridge and reservoir provides a dual stage vaporization of fuel to the fuel cell. Other features included are passive or active arrangements to increase the temperature of the fuel or reduce pressure in the fuel container to enhance rate of vaporization.Type: GrantFiled: September 16, 2003Date of Patent: February 14, 2012Assignee: The Gillette Company—South BostonInventors: Javit A. Drake, Andrew G. Gilicinski, Gordon G. Guay, Leslie Pinnell

Patent number: 7531271Abstract: A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell and defining a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises a single plastic frame or two separate plastic frames housing the anode and cathode material. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.Type: GrantFiled: August 9, 2004Date of Patent: May 12, 2009Assignee: The Gillette CompanyInventors: Jonathan M. Boulton, Stuart M. Davis, George Cintra, Leslie Pinnell, Charles E. O'Brien
