NOVELTY - A solid oxide fuel cell comprises a catalyst that promotes reforming dispersed within or upon a support structure of anode such that the catalyst has a first concentration at a first position and a second concentration at a second position, where the first position is closer to an anode flow channel entrance than the second position and the first concentration is lower than the second concentration.    USE - For automobile (claimed).    ADVANTAGE - The fuel cell has controlled internal reforming kinetic rates such that the fuel cells are subjected to lower amounts of internal stress.    DETAILED DESCRIPTION - A solid oxide fuel cell comprises a cathode (12); electrolyte layer (14) adjacent to the cathode; and anode (16) adjacent to the electrolyte layer. The anode comprises a support structure (24) defining at least a portion of an anode flow channel (22). The anode flow channel has an anode flow channel entrance (36) for the introduction of fuel to the solid oxide fuel cell and an anode flow channel exit. A catalyst that promotes reforming is dispersed within or upon the support structure such that the catalyst has a first concentration at a first position and a second concentration at a second position, where the first position is closer to the entrance than the second position and the first concentration is lower than the second concentration.    INDEPENDENT CLAIMS are also included for:    (A) automobile at least partially powered by the inventive solid oxide fuel cell; and    (B) controlling kinetic rates for internal reforming of fuel in solid oxide fuel cells having a cathode having a cathode flow channel and a cathode flow channel entrance and an anode having an anode flow channel and an anode flow channel entrance, comprising flowing fuel through the anode flow channel such that the fuel contacts a surface of the anode flow channel, the surface of the anode flow channel having a catalyst that promotes reforming dispersed within or upon the surface with a concentration profile such that the rate of the reforming reaction increase monotonically with distance from the anode flow channel entrance.    DESCRIPTION OF DRAWING(S) - The figure is an exploded view of a solid oxide fuel cell in which the anode, cathode, and electrolyte layer are arranged in parallel sheets.
