ABSTRACT:
The present invention provides structures and methods that utilize fuel reformation to assist in thermal management of a channel-less SOFC at the device cell and/or stack assembly level. At the device level, passive and/or active control of unreformed fuel, or a mixture of reformed and unreformed fuel, is used to inject fuel in a distributed manner along the anode chamber of the channel-less SOFC. The injected fuel can be controlled in its composition, pressure, velocities, and/or flow rates. Additionally, present invention provides thermal management across a plurality of fuel cells in a stack assembly by actively controlling fuel composition, pressure, velocities, and/or flow rates provided to fuel inlets of the fuel cells.
