10. A solid oxide fuel cell comprising a first electrode, an electrolyte and a second electrode, the first electrode comprising a first layer on the electrolyte to optimize the electrochemical activity at the electrolyte and a second layer on the first layer to provide electronic conduction perpendicular to the layers of the fuel cell, the cross-sectional area of the second layer in contact with the first layer being different at different positions such that electronic conduction perpendicular to the layers of the fuel cell is different at different positions in the second layer.
