Method of sealing a bipolar plate supported solid oxide fuel cell with a sealed anode compartment

Title: Method of sealing a bipolar plate supported solid oxide fuel cell with a sealed anode compartment

Abstract

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.

Method and apparatus for controlling mass flow rate of recycled anode tail gas in solid oxide fuel cell system

Patent Absmeier, John P.; Kelly, Sean M.; Geiger, Gail E.

In an SOFC stack system, a reformer supplies reformate to the stack. An anode tail gas portion is recycled into the reformer. An inline flowmeter indicates an apparent recycle flow rate. A map of anode tail gas composition as a function of fuel utilization efficiency U, reformer oxygen/carbon ratio O:C, and recycle percentage R is generated on a laboratory test bed at various recycle rates and fuel utilization rates. Compositions are sent through a flowmeter and a Coriolus mass flowmeter provide a Coriolus flow and sensor voltage function across the various compositions and flow rates to create an average curvemore »« less

Solid oxide fuel cell having a glass composite seal

Patent De Rose, Anthony J.; Mukerjee, Subhasish; Haltiner, Jr., Karl Jacob

A solid oxide fuel cell stack having a plurality of cassettes and a glass composite seal disposed between the sealing surfaces of adjacent cassettes, thereby joining the cassettes and providing a hermetic seal therebetween. The glass composite seal includes an alkaline earth aluminosilicate (AEAS) glass disposed about a viscous glass such that the AEAS glass retains the viscous glass in a predetermined position between the first and second sealing surfaces. The AEAS glass provides geometric stability to the glass composite seal to maintain the proper distance between the adjacent cassettes while the viscous glass provides for a compliant and self-healingmore »« less
