  • Solid oxide fuel cell systems with hot zones and two-stage tail gas combustors
    Patent number: 8197976
    Abstract: A solid oxide fuel cell system including a main plate, an inner cylinder attached to the main plate, an intermediate cylinder attached to the main plate such that the intermediate cylinder contains a cathode air stream, and an outer cylinder attached to the main plate. An exhaust annular gap is formed between the intermediate and outer cylinders such that hot exhaust gases flow through the exhaust annular gap and heat is transferred from the hot exhaust gases to the cathode air stream. The solid oxide fuel cell system may also include a two-stage tail gas combustor.
    Type: Grant

  • Method of measuring extent of cure of binder in products
    Patent number: 7991504
    Abstract: A method for determining the extent of cure of binder in a product comprising heating a sample of the product to vaporize free moisture in the sample and expel vaporized free moisture from the sample, measuring cure moisture content of the product, measuring binder content of the product, calculating a product ratio of cure moisture content to binder content, and comparing the product ratio of cure moisture content to binder content to a predetermined desirable ratio of cure moisture content to binder content.
