Abstract: The present invention relates to the field of battery cells, particularly to a pouch cell comprising a packaging seal, a heating element and a fault switch, wherein the fault switch will activate the heating element to generate heat to make the packaging seal delaminate when the inner space of the pouch cell reaches a predetermined pressure, such that the pouch cell vents. The mechanism and components of these venting concepts can be designed to be fully compatible with existing manufacturing methods and typical cell handling situations. The most favorable configuration has both vent device components outside the cell, with nothing passing through or even into the seal. Such a configuration has the advantage of having no impact on the seal integrity relative to a conventional pouch cell, is easy to manufacture, and has improved safety.

Abstract: A fuel cell stack assembly has a plurality of cells each having a fluid coolant conduit. A coolant feed manifold has a first inlet and a second inlet and is coupled to each fluid coolant conduit for distribution of fluid coolant within each cell. A pump is coupled for delivery of fluid coolant to the coolant feed manifold through the first and second inlets. A flow control assembly is configured to periodically modify the relative flow rates of fluid coolant through the first and second inlets so that stagnant regions in the coolant feed manifold are avoided. The flow control assembly may also be adapted to periodically interrupt the flow path between the pump and the manifold such that the fluid coolant is delivered to the manifold intermittently, thereby enabling low water flows below a minimum set point of the pump.
