20130157173 | ADHESIVE SEAL MEMBER FOR FUEL CELL - An adhesive seal member for a fuel cell of the present invention includes a cross-linked product of a rubber composition containing components (A) to (E): (A) at least one rubber component selected from ethylene-propylene rubber and ethylene-propylene-diene rubber, (B) an organic peroxide having a one-hour half-life temperature of 130° C. or less, (C) a crosslinking aid, (D) at least one adhesive component selected from a resorcinol compound and a melamine compound, an aluminate coupling agent, and a silane coupling agent, and (E) a softener having a pour point of −40° C. or less. If the ethylene-propylene rubber or the ethylene-propylene-diene rubber in (A) the rubber component has an ethylene content of 53% by mass or less, the rubber composition may be devoid of (E) the softener having a pour point of −40° C. or less. | 06-20-2013 |
20130196253 | FUEL CELL STACK HAVING INTERLOCKING FEATURES TO ENHANCE ADHESION OF GLASS SEAL TO SEALING SURFACES - A solid oxide fuel cell (SOFC) stack having a glass seal sandwiched between the sealing surfaces of adjacent cassettes, in which at least one cassette includes means for interlocking the glass seal onto the sealing surface of the cassette for improved adhesion and durability of the glass seal. The at least one cassette includes a plurality of perforations configured to receive and lock onto a portion of the glass seal. At least one of the perforations includes a through-hole having an exterior opening on the sealing surface and an interior opening on the interior surface of the cassette. A portion of the glass seal is received in the perforation forming a glass column in the through-hole and a flared glass end on the interior surface surrounding the interior opening. The flared glass end cooperates with the glass column to interlock the glass seal onto the cassette's sealing surface. | 08-01-2013 |
