A composite gas separation module includes a porous metal substrate; an intermediate layer that includes a powder having a Tamman temperature higher than the Tamman temperature of the porous metal substrate and wherein the intermediate layer overlies the porous metal substrate; and a dense hydrogen-selective membrane, wherein the dense hydrogen-selective membrane overlies the intermediate layer. The hybrid computer system includes an application server computer and at least two mainframe computers. In this way, the wire is subject to a minute downward suppressing force so that the wire can travel smoothly inside the arch-slide of the wire guide.
