Patent number: 7348092Abstract: A sealing technique is provided for forming complex and multiple seal configurations for fuel cells and other electrochemical cells. To provide a seal, for sealing chambers for oxidant, fuel and/or coolant, a groove network is provided extending through the various elements of the fuel cell assembly. A source of seal material is then connected to an external filling port and injected into the groove network, and the seal material is then cured to form the seal. There is thus formed a “seal in place”, that is robust and can accommodate variations in tolerances and dimensions, and that can be bonded, where possible, to individual elements of the fuel cell assembly. This avoids the difficulty, labor intensive cost and complexity of manually assembling many individual gaskets into complex groove shapes and the like. The seal material can be selected to be comparable with a wide variety of gases, liquid coolants and the like.Type: GrantFiled: November 14, 2003Date of Patent: March 25, 2008Assignee: Hydrogenics CorporationInventors: David G. Frank, Joseph Cargnelli, Lawrence Eugene Frisch, William Gordon Bradford, Myron Timothy Maxson, Brian Jeffery Swanton, Howard Stimson Travis

Patent number: 6936081Abstract: A system and reactor stack for generating hydrogen from a hydride solution in presence of a catalyst. The reactor stack includes a number of reactor plates and separator plates alternate with one another, to define reaction chambers alternating with coolant chambers. Each reactor plate has a first face defining a solution flow field and an opposing second face defining a coolant flow field. Each solution flow field comprises a common reaction chamber and a plurality of channels opening into the common reaction chamber. The catalyst is provided in the common reaction chamber. Each reaction chamber is configured to receive the hydride solution and to bring at least a portion of the hydride solution in contact with the catalyst. Each reaction chamber is in fluid communication with an adjacent reaction chamber and each coolant chamber is in fluid communication with an adjacent coolant chamber.Type: GrantFiled: December 17, 2001Date of Patent: August 30, 2005Assignee: Hydrogenics CorporationInventors: Ali Rusta-Sallehy, Xuesong Chen, David G.
