An example energy dissipation device for controlling a fuel cell fluid includes a conduit extending in longitudinal direction between a first opening and a second opening. A flow control insert is configured to be received within the conduit. The flow control insert is configured to cause a fuel cell fluid to flow helically relative to the longitudinal direction.

Energy dissipation device for controlling flow of a fuel cell fluid

In a fuel cell stack, an inlet fuel distributor () comprises a plurality of fuel distributing passageways (--) of substantially equal length and equal flow cross section to uniformly distribute fuel cell inlet fuel from a fuel supply conduit () to a fuel inlet manifold (). The conduits may be either channels (-) formed within a plate () or tubes (-). The channels may have single exits () or double exits () into the fuel inlet manifold.

Small volume, fuel cell inlet fuel gas distributor having low pressure drop

An inlet fuel distributor (-) has a permeable baffle () between a fuel supply pipe () and a fuel inlet manifold () causing fuel to be uniformly distributed along the length of the fuel inlet manifold. A surface () may cause impinging fuel to turn and flow substantially omnidirectionally improving its uniformity. Recycle fuel may be provided () into the flow downstream of the fuel inlet distributor. During startup, fuel or inert gas within the inlet fuel distributor and the fuel inlet manifold may be vented through an exhaust valve () in response to a controller () so as to present a uniform fuel front to the inlets of the fuel flow fields ().
