Patent number: 8652709Abstract: Methods of sealing a bipolar plate supported solid oxide fuel cell with a sealed anode compartment are provided. The solid oxide fuel cell includes a cathode, an electrolyte, and an anode, which are supported on a metallic bipolar plate assembly including gas flow fields and the gas impermeable bipolar plate. The electrolyte and anode are sealed into an anode compartment with a metal perimeter seal. An improved method of sealing is provided by extending the metal seal around the entire perimeter of the cell between an electrolyte and the bipolar plate to form the anode compartment. During a single-step high temperature sintering process the metal seal bonds to the edges of the electrolyte and anode layers, the metal foam flow field and the bipolar plate to form a gastight containment.Type: GrantFiled: November 11, 2009Date of Patent: February 18, 2014Assignee: UChicago Argonne, LLCInventors: John David Carter, Joong-Myeon Bae, Terry Alan Cruse, James Michael Ralph, Deborah J.
