The present invention provides a solid oxide fuel cell in which kinetic
rates for internal reforming are controlled. The solid oxide fuel cell
comprises a cathode, an electrolyte layer adjacent to the cathode, and an
anode adjacent to the electrolyte layer. The anode used in the cell of
the invention includes a support structure which defines at least a
portion of an anode flow channel and a catalyst that promotes reforming.
The anode flow channel has an anode flow channel entrance for the
introduction of fuel to the solid oxide fuel cell and an anode flow
channel exit for removing unreacted fuel and/or by-products. The catalyst
is dispersed within or upon the support structure such that the rate of
reforming increases at increasing distances from the anode flow channel
entrance. The present invention also provides a method of controlling
internal reforming kinetic rates in a solid oxide fuel cell.
