Abstract:
1. A solid oxide fuel cell component comprising: a porous gas permeable support structure having a surface; at least first, second and third solid oxide fuel cells being arranged in spaced apart relationship on the surface of the porous gas permeable support structure, such that the first cell is adjacent to the second cell, the second cell is adjacent to the third cell, and the cells are arranged in electrical series; the first, second and third cells each comprising a dense non-porous gas tight electrolyte member, a porous gas permeable anode, and a porous gas permeable cathode; the anode of the first cell being connected to the cathode of the adjacent second cell by a first dense non-porous and gas tight interconnector; the first interconnector having a bottom surface contacting the surface of the support, a first side surface contacting the anode of the first cell, a top surface, and a second side surface spaced apart from the anode of the second cell; the anode of the first cell contacting a portion of the top surface of the first interconnector and the cathode of the second cell contacting another portion of the top surface of the first interconnector; the anode of the second cell being connected to the cathode of the adjacent third cell by a second dense non-porous and gas tight interconnector; the second interconnector having a bottom surface contacting the surface of the support, a first side surface contacting the anode of the second cell, a top surface, and a second side surface spaced apart from the anode of the third cell; the anode of the second cell contacting a portion of the top surface of the second interconnector and the cathode of the third cell contacting another portion of the top surface of the second interconnector; and the electrolyte member of the second cell being arranged between the anode and cathode of the second cell, a first end of the electrolyte member of the second cell contacting the surface of the support between the second side surface of the first interconnector and a side surface of the anode of the second cell, a second end of the electrolyte member of the second cell contacting the top surface of the second interconnector between the anode of the second cell and the cathode of the third cell, and the electrolyte member of the second cell is spaced apart from the cathode of the third cell by a portion of the top surface of the second interconnector.
