A fuel cell system anode tail gas oxidizer (ATO) includes an inner ATO wall, an outer ATO wall, and a first catalyst ring disposed in a chamber formed between the inner ATO wall and the outer ATO wall. The first catalyst ring includes an inner wall, an outer wall, and a matrix disposed between the inner wall and the outer wall and loaded with an oxidation catalyst.

Fuel cell system including catalyst ring anode tail gas oxidizer

A fuel cell system includes a fuel cell stack configured to generate electricity, an anode exhaust and a cathode exhaust, an anode tail gas oxidizer (ATO) configured to oxidize the anode exhaust using the cathode exhaust, and a low-temperature oxidizer (LTO) configured to catalyze oxidation of carbon monoxide (CO) in the cathode exhaust output from the ATO.

Solid oxide fuel cell system containing low temperature oxidizer and method of operating same with reduced carbon monoxide output

A fuel cell column includes a stack of alternating fuel cells and interconnects, where the interconnects separate adjacent fuel cells in the stack and contain fuel and air channels which are configured to provide respective fuel and air to the fuel cells. a manifold plate containing a bottom inlet hole and a bottom outlet hole located in a bottom surface of the manifold plate, top outlet holes and top inlet holes formed in opposing sides of a top surface of the manifold plate, outlet channels fluidly connecting the top outlet holes to the bottom inlet hole, and inlet channels fluidly connecting the top inlet holes to the bottom outlet hole, and a mitigation structure configured to reduce stress applied to the stack due to at least one of a shape mismatch or coefficient of thermal expansion mismatch between the stack and the manifold plate.
