20100119917 | Seal compositions, methods, and structures for planar solid oxide fuel cells - A seal composition includes a first alkaline earth metal oxide, a second alkaline earth metal oxide which is different from the first alkaline earth metal oxide, aluminum oxide, and silica in an amount such that molar percent of silica in the composition is at least five molar percent greater than two times a combined molar percent of the first alkaline earth metal oxide and the second alkaline earth metal oxide. The composition is substantially free of boron oxide and phosphorus oxide. The seal composition forms a glass ceramic seal which includes silica containing glass cores located in a crystalline matrix comprising barium aluminosilicate, and calcium aluminosilicate crystals located in the glass cores. | 05-13-2010 |
20100119918 | SEALING STRUCTURE FOR FUEL CELL - An inner sealing member and an outer sealing member are provided in juxtaposition in the outer peripheral portion of a reaction gas manifold. Preferably, the inner sealing member, disposed closest to the reaction gas manifold, is composed of an acid-resistant material, and the outer sealing member is composed of a material whose performance is not significantly degraded at low temperature. Ethylene propylene rubber or fluorine rubber can be used as the inner sealing member. Silicone rubber can be used as the outer sealing member. | 05-13-2010 |
