  • Publication number: 20180230171
    Abstract: Compounds and method of preparation of Si—X and Ge—X compounds (X=N, P, As and Sb) via dehydrogenative coupling between the corresponding unsubstituted silanes and amines (including ammonia) or phosphines catalyzed by metallic catalysts is described. This new approach is based on the catalytic dehydrogenative coupling of a Si—H and a X—H moiety to form a Si—X containing compound and hydrogen gas (X=N, P, As and Sb). The process can be catalyzed by transition metal heterogenous catalysts such as Ru(0) on carbon, Pd(0) on MgO) as well as transition metal organometallic complexes that act as homogeneous catalysts. The —Si—X products produced by dehydrogenative coupling are inherently halogen free. Said compounds can be useful for the deposition of thin films by chemical vapor deposition or atomic layer deposition of Si-containing films.

  • Patent number: 10003091
    Abstract: According to an example embodiment, a method of making a phosphoric acid fuel cell component includes situating at least one polymer film layer against a permeable component layer. The polymer film layer comprises a polymer that is chemically resistant to phosphoric acid. The polymer film layer is melted. The permeable component layer is impregnated with the melted polymer to thereby establish a region on the component layer that is impermeable to phosphoric acid. The impregnated region also provides a seal against reactant leakage from the component.

  • Patent number: 10003090
    Abstract: According to an example embodiment, a method of making a fuel cell component includes permeating at least a portion of a component layer with a polymer. The portion of the component layer is adjacent an edge of the component layer. Some of the polymer is allowed to extend beyond the edge to thereby establish a flap beyond the edge of the component layer. A fuel cell component includes a component layer having a portion adjacent an edge of the layer that is impregnated with a polymer material and a flap of the polymer material extending beyond the edge.

  • Publication number: 20180162883
    Abstract: Halogen free amine substituted trisilylamine and tridisilylamine compounds and a method of their preparation via dehydrogenative coupling between the corresponding unsubstituted trisilylames and amines catalyzed by transition metal catalysts is described. This new approach is based on the catalytic dehydrocoupling of a Si—H and a N—H moiety to form an Si—N containing compound and hydrogen gas. The process can be catalyzed by transition metal heterogenous catalysts such as Ru(0) on carbon, Pd(0) on MgO) as well as transition metal organometallic complexes that act as homogeneous catalysts. The —Si—N containing products are halide free. Such compounds can be useful for the deposition of thin films by chemical vapor deposition or atomic layer deposition of Si containing films.

    Abstract: According to an example embodiment, a fuel cell component manufacturing assembly includes a support member that is configured to be situated adjacent the fuel cell component to provide support for the component. The support member has a perimeter corresponding to a perimeter of the component. A platen member has a configuration corresponding to at least a portion of the support member for being received against a portion of the component. A temperature of the platen member is controllable to achieve a desired temperature of a material situated adjacent the platen member. The platen member has a surface area that is less than a surface area of the component such that only the portion of the component is subject to pressure resulting from a force urging the platen member and the support member together with the component between the support member and the platen member.
