Appl. No.:

12/379299

Inventors:

Martin Perry - Sunnyvale CA, US
Swaminathan Venkataraman - Cupertino CA, US

Assignee:

Bloom Energy Corporation - Sunnyvale CA

International Classification:

H01M 8/00

US Classification:

429408, 429423, 429434

Abstract:

A fuel cell system includes at least one fuel cell stack, a fuel inlet conduit, and a fuel heat exchanger containing a fuel reformation catalyst. The fuel heat exchanger is connected to the fuel inlet conduit and to at least one fuel cell system exhaust conduit which in operation provides a high temperature exhaust stream to the fuel heat exchanger. The fuel heat exchanger is thermally integrated with an anode tail gas oxidizer (ATO) exhaust conduit such that in operation an ATO exhaust stream in the ATO exhaust conduit heats a fuel inlet stream passing through the heat exchanger.
