Abstract:
1. A fuel cell system, comprising: a fuel cell stack; a thermal regulating assembly configured to selectively deliver a flow of a liquid heat exchange fluid having a temperature to the fuel cell stack, wherein the thermal regulating assembly comprises: a pump assembly configured to selectively propel a flow of the liquid heat exchange fluid within the fluid circuit; and a thermostatic distribution assembly configured to automatically apportion the flow of the return stream between a bypass stream that flows to the bypass conduit and a recycle stream that flows to the liquid reservoir, wherein the apportioning is directly responsive to a temperature of the return stream, and further wherein the apportioning is not directly responsive to a temperature of the liquid heat exchange fluid that is supplied to the fuel cell stack in the delivery conduit.
