Abstract
The present teachings relate to solid oxide fuel cells with internal reforming capability. The solid oxide fuel cell generally includes a cathode, an electrolyte, an anode, and a catalyst layer in contact with the anode. The catalyst layer can include a support membrane and a reforming catalyst layer associated with the support membrane. In some embodiments, the reforming catalyst can include one or more partial oxidation reforming catalysts. The present teachings also provide methods of making and operating the solid oxide fuel cells described above.
Claims20
A fuel cell comprising:
- a cathode;
- an electrolyte;
- an anode;
- and
- a catalyst layer in contact with the anode, wherein the catalyst layer comprises a partial oxidation reforming catalyst associated with a support membrane.
A fuel cell comprising:
- a cathode;
- an electrolyte;
- an anode;
- and
- a catalyst layer in contact with the anode, wherein the catalyst layer comprises a reforming catalyst associated with a support membrane, the support membrane comprising one or more metal oxides selected from aluminum oxide, zirconium oxide, titanium oxide, lanthanum strontium oxide, cerium oxide, molybdenum oxide, zinc oxide, and calcium titanium oxide.
A method of making an internally reforming fuel cell, the method comprising:
- depositing a support slurry onto at least a portion of an anode of a fuel cell, wherein the support slurry comprises a support material and a solvent;
- drying the support slurry to form a support membrane;
- and
- associating a partial oxidation reforming catalyst with the support membrane.
