A solid oxide fuel cell component () comprises a plurality of solid oxide fuel cells () arranged in spaced apart relationship, and in electrical series, on a surface of the porous gas permeable support structure (). Each solid oxide fuel cell () comprises a dense gas tight electrolyte member (), a porous gas permeable first electrode () and a porous gas permeable second electrode (). Each electrolyte () is arranged in contact with a corresponding one of the first electrodes (), each second electrode () is arranged in contact with a corresponding one of the electrolytes (). Each of the first electrodes () is arranged in contact with the surface of the support structure (). The interconnectors (), the peripheral seal layer () and the electrolytes () are arranged to encapsulate all of the first electrodes () except for the surfaces of the first electrodes () in contact with the surface of the support structure () to prevent leakage of reactant from the first electrodes ().

Solid oxide fuel cell component and a method of manufacturing a solid oxide fuel cell component

A solid oxide fuel cell () comprises an anode electrode (), a cathode electrode () and an electrolyte () between the anode electrode () and the cathode electrode (). A gaseous fuel is supplied to an anode chamber () partially defined by the anode electrode () and a gaseous oxidant is supplied to a cathode chamber () partially defined by the cathode electrode (). The electrolyte () comprises a first dense non-porous layer (), a second porous layer () on the first dense non-porous layer () and a third dense non-porous layer () on the second porous layer (). The anode electrode () is arranged on the first dense non-porous layer () and the cathode electrode () is arranged on the third dense non-porous layer (). The second porous layer () acts as a buffer between the first dense non-porous layer () and the third dense non-porous layer () to prevent defects propagating between the layers () and to prevent fuel and oxidant leaking through the electrolyte ().
