NanoDynamics™ Inc. has been granted a U.S. patent on solid oxide fuel cell (SOFC) structures. U.S. patent number 6,998,187, "Solid Oxide Fuel Cells with Novel Internal Geometry," describes ways of manufacturing compact durable SOFCs with high efficiency. "Manufacturing fuel cells for optimal space utilization, robust construction and ease of manifolding is key to their success in portable power applications," said Caine Finnerty, Ph.D., technical director - Fuel Cells and the primary inventor of this technology. "This patent describes some of the technology we have used over the past three years to increase the output of our cells by a factor of five, making them highly competitive in this rapidly developing field. Optimizing the internal geometry of the cell has helped to reduce losses associated with current collection and fuel utilization while providing some novel opportunities for gas introduction and system design."
