Abstract: A fuel cell system is provided which includes a mounting system for a manifold having a mounting plate. The fuel cell system also includes a fuel cell stack with a first end and a second end. The first end of the fuel cell stack includes at least one port in communication with the manifold. A clamping system is disposed on the second end of the fuel cell stack and is operable to engage the mounting plate of the manifold to couple the manifold to the fuel cell stack.

Abstract: A temperature control system and method for a fuel cell stack cooling system is disclosed. The temperature control system includes a coolant circulation line for circulating a coolant to and from a fuel cell stack. A coolant pump is provided in the coolant circulation line, and a pump ΔP sensor is provided in fluid communication with the coolant circulation line on inlet and outlet sides of the coolant pump. The pump ΔP sensor measures a change in pump pressure between the inlet and outlet sides of the coolant pump. A pump map is provided having correlated values of pump speed, change in pump pressure and coolant flow rate for correlating the coolant flow rate with the pump speed and the change in pump pressure to attain a desired coolant flow rate for optimum fuel stack cooling.

Abstract: An airflow control system and method for a fuel cell includes a compressor that supplies air to a storage chamber for storing the air. Fuel cell subsystems are connected to the air storage chamber. Each of the fuel cell subsystems includes a flow controller and flow sensor. A sensor measures air pressure in the storage chamber. A controller polls the flow controllers of the fuel cell subsystems for a minimum required air pressure for the fuel cell subsystems. The controller selects a highest minimum required air pressure. The controller controls the compressor to provide the highest minimum required pressure in the air storage chamber. The air storage chamber includes tubing, a manifold or both.
