Abstract
A solid oxide fuel cell having a plurality of individual cells. A solid oxide fuel cell has an anode and a cathode with electrolyte disposed therebetween, and the anode, cathode and interconnect elements are comprised of substantially one material.
Claims20
A solid oxide fuel cell having a plurality of individual cells using a conventional interconnect material with each of said cells comprising:
- an anode consisting essentially of said conventional interconnect material;
- a cathode consisting essentially of said conventional interconnect material with electrolyte disposed between said anode and cathode, said anode and cathode being thin enough to provide short conduction paths and low voltage losses;
- and
- an interconnect element consisting essentially of said conventional interconnect material coupled to said anode and said cathode with said interconnect element.
1 more element
A solid oxide fuel cell having a plurality of individual cells with said individual cells comprising:
- an anode and a cathode;
- a gas flow channel described by at least a first interconnect material element;
- and
- a fuel flow channel described at least in part by a second interconnect element and said first interconnect material element, said second interconnect material element and said anode and said cathode consisting essentially of the same interconnect material with said anode and said cathode being dimensioned to provide good electrical properties.
1 more element
A solid oxide fuel cell having a plurality of individual cells with each of said cells comprising;
- electrodes having an electrolyte disposed there between;
- and
- interconnect material elements between said electrodes with said electrodes and said interconnect material elements consisting essentially of the same elemental constituents and said electrodes being dimensioned to provide good electrical properties.
