Abstract
Official abstract text for this publication.
A fuel cell system conduit assembly includes a dielectric tube having a first end and a second end, a metallic first flange press-fit to the first end of the dielectric tube, a metallic second flange press-fit to the second end of the dielectric tube, a first snap ring disposed between the first flange and the dielectric tube, and a second snap ring disposed between the second flange and the dielectric tube.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel cell system conduit assembly, comprising: a dielectric tube having a first end and a second end; a metallic first flange press-fit to the first end of the dielectric tube; a metallic second flange press-fit to the second end of the dielectric tube; a first snap ring disposed between the first flange and the dielectric tube; and a second snap ring disposed between the second flange and the dielectric tube. 2. The conduit assembly of claim 1 , further comprising: a first washer and a first seal disposed between the first flange and the first end of the dielectric tube and formed of a glass or a glass-ceramic material; and a second washer and a second seal disposed between the second flange and the second end of the dielectric tube and formed of a glass or a glass-ceramic material. 3. The conduit assembly of claim 1 , wherein: the first snap ring is disposed in a groove formed in the dielectric tube and a groove the first flange; and the second snap ring is disposed in a groove formed in the dielectric tube and a groove formed in the second flange. 4. The conduit assembly of claim 3 , wherein: the first snap ring is configured to maintain a compressive force between the first flange and the first end of the dielectric tube; and the second snap ring is configured to maintain a compressive force between the second flange and the second end of the dielectric tube. 5. The conduit assembly of claim 1 , further comprising first and second transition tubes respectively fluidly connected to the first and second flanges. 6. The conduit assembly of claim 5 , wherein the first and second flanges comprise support rings that respectively extend away from the dielectric tube and receive the first and second transition tubes, respectively. 7. The conduit assembly of claim 5 , further comprising first and second bellows respectively connected to the first and second transition tubes. 8. The conduit assembly of claim 1 , wherein the first snap ring is a partial ring and the second snap ring is a partial ring. 9. The conduit assembly of claim 1 , wherein the conduit assembly is incorporated into a fuel conduit which is fluidly connected to a fuel cell column. 10. The conduit assembly of claim 1 , wherein the first and second flanges comprise stainless steel or a nickel chromium alloy. 11. The conduit assembly of claim 1 , wherein the dielectric tube comprises a ceramic material. 12. The conduit assembly of claim 11 , wherein the ceramic material comprises, alumina, zirconia toughened alumina, or silicon nitride. 13. The conduit assembly of claim 11 , wherein the dielectric tube is not directly welded or brazed to any other component of the conduit assembly. 14. A fuel cell system, comprising: a fuel cell column comprising a fuel manifold; and a conduit assembly of claim 1 fluidly connected to the fuel manifold.
