摘要: An exemplary fuel cell component includes a generally planar body having a total area defined by a length and width of the body. A first portion of the total area is occupied by a first fuel cell features that renders the first portion unusable for at least one fuel cell function. A second portion of the total area is occupied by a second fuel cell feature that renders the second portion unusable for the fuel cell function. A third portion of the total area is considered an active area of the component that is useful for the fuel cell function. An aspect ratio of the length to the width of the generally planar body is dependent on a dimension of the first portion and a dimension of the second portion.

摘要: An exemplary flow field includes a plurality of flow channel portions. There are n inlet portions configured for introducing a fluid into the flow field. A plurality of first pass portions direct fluid flow in a first direction. A plurality of second pass portions direct fluid flow in a second direction that is generally parallel to and opposite to the first direction. A plurality of third pass portions direct fluid flow in the first direction. n outlet portions are configured to allow fluid to exit the flow field. n is an integer and a number of the portions in at least one plurality of pass portions is a non-integer multiple of n.

摘要: An exemplary method includes of operating a fuel cell at a first power output level that includes a plurality of operation parameters. Each operation parameter has a value to satisfy a first power demand. A change between the first power demand and a second power demand is determined. At least a first one of the operation parameters is maintained at a value corresponding to the first power output level or at an intermediate value while at least a second one of the operation parameters is changed to a value corresponding to a second power output level to satisfy the second power demand. The first operation parameter is delayed from changing to a value corresponding to the second power output level until a predetermined criterion is met.

摘要: 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.
