Abstract:
A thermal energy management system 10 for solid oxide fuel cells includes a monolithic small cell extrusion type heat exchanger 12 coupled to an SOFC stack 14. In operation, a flow of air having a selected temperature is passed through the heat exchanger cells 18 and thermal energy flowing into and out of said SOFC stack 14 is managed primarily by radiation coupling between said SOFC stack 14 and said heat exchanger 12. The system 10 further provides management of the temperature distribution around the SOFC 14 to meet outer skin temperature design targets and to control the inlet gas temperatures for the SOFC 14. The system 10 provides a compact, efficient method for SOFC thermal energy management particularly well suited for transportation applications.
Abstract:
Fuel reformers 100,200 and methods for using fuel reformers 100,200 are disclosed herein. In one embodiment, the fuel reformer 100,200 can comprise: an oxidant inlet, a mixing zone 38 capable of receiving the oxidant and vaporized fuel to form a fuel mixture 58, a reforming zone 40 disposed downstream of and in fluid communication with the mixing zone 38, wherein the reforming zone 40 is capable of converting the fuel mixture 58 into a gas stream 60, and a passive heat exchanger 24 disposed in thermal communication with the gas stream 60 and capable of heating the fuel prior to introduction to the mixing zone 38.
