An intramedullary nail (20) defining a bore (34) is inserted into a medullary canal (26) of a bone (24). A threaded fastener (22) has a compression portion (48) presenting a compression portion diameter (DCP) and a threaded portion (50) presenting a threaded portion diameter (DTP). The fastener (22) extends through a near cortex hole (40) and/or a far cortex hole (42), and the threaded portion (22) threadedly engages the bore (34). A compression transmission device (54) is disposed between a head (44) of the fastener (22) and the intramedullary nail (20) for transmitting the compressional load of the threaded fastener …

A current producing cell has anode flow plates 22 and cathode flow plates 20. Each of the flow plates 20, 22 defines a membrane face 26, a collector face 24, and a center axis C perpendicular to the membrane face 26 and the collector face 24. Each of the collector faces 24 define a plurality of cooling channels 74, 76, 78 and a plurality of transport channels 62, 64. The cooling channels 74, 76, 78 of the cathode flow plates 20 extend radially relative to the center axis C thereof to overlap the transport channels 62, 64 of the anode …
