An exemplary method of cooling a fuel cell includes directing coolant through a coolant supply channel near at least one reactant flow channel. The coolant supply channel extends from a coolant inlet spaced from a reactant inlet to a coolant outlet. The coolant supply channel includes a first portion starting at the coolant inlet and a second portion near the reactant inlet. The first portion facilitates coolant flow from the coolant inlet directly toward the second portion. The second portion includes a plurality of channel sections that collectively facilitate coolant flow in a plurality of directions along the second portion near the reactant inlet. The coolant supply channel includes a third portion between the second portion and the coolant outlet.

An exemplary fuel cell device includes a cell stack assembly having a plurality of fuel cells. A vapor barrier tape is wrapped around at least a portion of an exterior of the cell stack assembly. An exemplary method of managing moisture within a fuel cell stack assembly includes covering at least a portion of an exterior of the cell stack assembly with a vapor barrier tape to thereby maintain moisture within the cell stack assembly.

An exemplary fuel cell component includes a plate having a plurality of channels. At least a first one of the channels is configured differently than others of the channels so that the first channel provides a first cooling capacity to a selected portion of the plate. The others of the channels provide a second, lesser cooling capacity to at least one other portion of the plate.

Fuel cell component having selected cooling capacity distribution

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.
