Abstract: A method for operating a fuel cell system comprising a fuel cell assembly of a plurality of fuel cells configured to generate electrical power from a fuel flow and an oxidant flow to the plurality of fuel cells, the fuel cell assembly arranged in combination with a coolant storage module configured to supply the fuel cell assembly with a flow of coolant, the method performed when the temperature of the coolant in the coolant storage module is below a coolant temperature threshold and comprises; a first phase performed prior to activation of a coolant pump configured to deliver coolant from the coolant storage module to the fuel cell assembly and a second phase performed after activation of the coolant pump.

Abstract: Disclosed is a cooling module for use in a fuel cell system, the module includes a tank configured to receive a coolant therein, a coolant, a pump in fluid communication with the coolant in the tank and the fuel cell system, the pump being configured to transport the coolant to the fuel cell system, a heating element within the coolant in the tank, the heating element configured to heat the coolant, and at least one sensor in signal communication with a controller and in fluid communication with the tank. The sensor is configured to detect a change corresponding to the presence or absence of sufficient liquid coolant to initiate said pump, and the controller processes sensor data and is configured to actuate the pump.
