SELECTIVELY ROTATED FLOW FIELD FOR THERMAL MANAGEMENT IN A FUEL CELL STACK
Solid oxide fuel cells comprise an electrolyte sandwiched between a cathode and an anode. Oxygen reacts with electrons at the cathode to form oxygen ions, which are conducted through the ion-conducting ceramic electrolyte to the anode. At the anode, oxygen ions combine with available fuel (e.g., hydrogen and carbon monoxide) to form products (e.g.: water and carbon dioxide) thereby liberating electrons to produce electrical power. The technology can equally be run in reverse to form fuel gases and oxygen when supplied with appropriate reactants (e.g., water and carbon dioxide) and electrical power. In this case the technology is termed a solid oxide electrolysis cell. SOFC development has seen a multitude of approaches (anode, cathode or electrolyte supported, monolithic ceramic vs metallic interconnects, planar vs tubular and variants thereof). The prime challenge to commercialize the technology has been the simultaneous achievement of marketable price, reasonable performance, and useful lifetime. These drivers are closely related.

FuelCell Energy also filed patent for a fuel cell system with an ejector for recycling exhaust
The fuel cell module has an anode section that outputs an anode exhaust stream, which is then split into an anode recycle stream and a system outlet stream. The ejector has a low pressure inlet that receives a suction stream and a motive inlet that receives a motive stream, both of which are portions of the anode recycle stream. The ejector outputs an ejector output stream, which is then used as an input stream for the anode section.

Abstract: A method of manufacturing a proton-conducting fuel cell includes assembling a green anode-electrolyte half-cell by forming an anode substrate layer having an upper surface and a lower surface, forming an anode functional layer on the upper surface of the anode substrate layer, forming an electrolyte layer on an upper surface of the anode functional layer, and forming a stress balancing layer on the lower surface of the anode substrate layer. The method further includes positioning the green anode-electrolyte half-cell on kiln furniture inside a sintering kiln and sintering the green anode-electrolyte half-cell using SSRS to an anode-electrolyte half-cell.
