Patent number: 9046309Abstract: A membrane cartridge is manufactured by repeatedly folding and joining two strips of membrane to form a cross-pleated cartridge with a stack of openings or fluid passageways configured in an alternating cross-flow arrangement. The cartridge can be modified for other flow configurations including co-flow and counter-flow arrangements. Methods for manufacturing such cross-pleated membrane cartridges, as well as apparatus used in the manufacturing process are described. Cross-pleated membrane cartridges comprising water-permeable membranes can be used in a variety of applications, including in heat and water vapor exchangers. In particular they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams being directed into and out of buildings.Type: GrantFiled: August 5, 2014Date of Patent: June 2, 2015Assignee: DPoint Technologies Inc.Inventors: Greg Montie, James Franklin Dean, Curtis Mullen, Robert Hill

Patent number: 7838169Abstract: A fuel cell cathode flow field has multiple channels each with a cross-sectional area that varies along the length of the channel such that oxygen availability at every lengthwise position along the channel is kept substantially constant for a given channel length and air stoichiometry ratio. Each channel comprises a flat floor with substantially constant depth and a pair of side walls extending upwardly from the floor; the side walls each taper inwards from channel inlet to outlet with a convex curve relative to the channel centreline. Achieving substantially uniform oxygen availability throughout the flow field results in substantially uniform current density throughout the flow field, which is desirable for efficient fuel cell operation and improved performance.Type: GrantFiled: December 29, 2005Date of Patent: November 23, 2010Assignee: Power Disc Development Corporation Ltd.Inventors: Greg Montie, Rodney Bruce Redlich, David Earl Leger

Publication number: 20080085437Abstract: A heat and humidity exchanger comprises a pleated membrane cartridge disposed in a housing. The cartridge comprises a pleated water-permeable membrane via which heat and humidity can be transferred between two fluid streams. A flow field element is disposed within some or all of the folds of the pleated membrane, for directing the stream over the inner surfaces of the folds. The flow field path defined by the flow field element enhances flow distribution across one or both membrane surfaces, controlling the relative flow paths of the two streams on opposite sides of the membrane and reducing the pressure drop across the heat and humidity exchanger. The flow field elements provide improved water transfer and allow for a more compact device. The flow field elements can also assist in supporting the pleated membrane and controlling the pleat spacing within the pleated membrane cartridge. The heat and humidity exchanger is particularly suitable for fuel cell and energy recovery ventilator (ERV) applications.Type: ApplicationFiled: September 28, 2007Publication date: April 10, 2008Inventors: James Dean, Chad Comeault, David Kadylak, Greg Montie
