Abstract
Official abstract text for this publication.
A porous solid oxide fuel cell (PSOFC) system for electricity and syngas co-generation. The system has a porous layer, a porous electrolyte layer with catalyst, a porous anode layer, and a porous catalyst layer. A fuel air/O 2 mixture is introduced from through the porous cathode layer so that it next passes through the porous electrolyte layer with catalyst, then the porous anode layer, and finally the porous catalyst layer. Syngas exits the porous catalyst layer with electricity being produced across the anode and cathode layers.
First claim
Opening claim text (preview).
What is claimed is: 1. A porous solid oxide fuel cell, comprising: a porous cathode layer; a porous electrolyte and catalyst layer adjoining the porous cathode layer; a porous anode layer adjoining the porous electrolyte and catalyst layer; and a porous catalyst layer adjoining the porous anode layer. 2. The fuel cell of claim 1 , wherein the porous cathode layer, the porous anode layer, the porous electrolyte and catalyst layer and the porous catalyst layer are formed into a tube. 3. The fuel cell of claim 2 , wherein the porous cathode layer is the outermost layer of the tube. 4. The fuel cell of claim 3 , wherein an end of the tube is closed. 5. The fuel cell of claim 2 , wherein the porous cathode layer is the innermost layer of the tube. 6. The fuel cell of claim 5 , wherein an end of the tube is closed. 7. The fuel cell of claim 1 , wherein each of the porous cathode layer, the porous cathode layer, the porous electrolyte and catalyst layer and the porous catalyst layer extend along parallel planes. 8. A method of co-generating electricity and syngas, comprising the steps of: providing a porous solid oxide fuel cell having a porous cathode layer, a porous electrolyte and catalyst layer adjoining the porous cathode layer, a porous anode layer adjoining the porous electrolyte and catalyst layer, and a porous catalyst layer adjoining the porous anode layer; introducing a mixture of fuel and oxygen into the porous cathode layer; collecting syngas from the porous catalyst layer; and collecting electricity across the porous cathode and porous anode layers. 9. The method of claim 8 , wherein the porous cathode layer, the porous cathode layer, the porous electrolyte and catalyst layer and the porous catalyst layer are formed into a tube. 10. The method of claim 9 , wherein the porous cathode layer is the outermost layer of the tube. 11. The method of claim 9 , wherein the wherein the porous cathode layer is the innermost layer of the tube. 12. The method of claim 9 , wherein the step of providing a porous solid oxide fuel cell comprises providing a series of stacked porous solid oxide fuel cells. 13. The method of claim 8 , wherein the step of introducing a mixture of fuel and oxygen into the porous cathode layer comprising injecting the mixture of fuel and oxygen into the tube and the step of collecting syngas from the porous catalyst layer comprises collecting syngas from around the outside of the tube. 14. The method of claim 8 , wherein the step of introducing a mixture of fuel and oxygen into the porous cathode layer comprising introducing the mixture of fuel and oxygen into the outside of the tube and the step of collecting syngas from the porous catalyst layer comprises collecting syngas from inside of the tube.
