Abstract
A solid oxide fuel cell module () comprises a plurality of fuel cells (). Each fuel cell () comprises a first electrode (), an electrolyte () and a second electrode (). A plurality of interconnectors () are arranged to electrically connect the fuel cells () in electrical series. Each interconnector () electrically connects a first electrode () of one fuel cell () to a second electrode () of an adjacent fuel cell (). The first electrode () comprises a first layer (A) on the electrolyte (to optimize the electrochemical activity at the electrolyte () and a second layer (B) on the first layer (A) to provide electronic conduction perpendicular to the layers () of the fuel cell (). The second layer (B) is arranged such that electronic conduction perpendicular to the layers ()) of the fuel cell () is different at different positions in the second layer (B).
