Single chamber solid oxide fuel cell architecture for high temperature operation

摘要

The present invention provides a solid oxide fuel cell system comprising at least one fuel cell and at least one gas flow channel to deliver a reactant mixture. The fuel cell comprises at least one chamber to house at least one anode, at least one cathode, and at least one electrolyte, and the fuel cell is adapted to receive a reactant mixture comprising reactants mixed prior to delivery to the fuel cell. The one or more gas flow channels for delivering the reactant mixture have characteristic dimensions that are less than a quench distance of the reactant mixture at an operating temperature within the solid oxide fuel cell system.
