Abstract: A fuel cell system includes a stacked assembly, a resonance determining unit, and a controller. The stacked assembly includes a plurality of unit cells stacked together. Each of the unit cells includes an electrolyte membrane, and a pair of electrodes between which the electrolyte membrane is sandwiched. The resonance determining unit is configured to determine whether vibration of the stacked assembly which occurs during running of a vehicle is within a resonance region of the stacked assembly. The controller is configured to change a natural frequency of the stacked assembly such that the vibration of the stacked assembly falls outside the resonance region, if the resonance determining unit determines that the vibration of the stacked assembly is within the resonance region.

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.

Abstract: A fuel cell system includes an air compressor that supplies oxidant gas to a fuel cell installed in a fuel cell vehicle, a measured rotational speed acquirer that acquires a measured value of rotational speed of the air compressor, and a controller that calculates a rotational speed command value of the air compressor based on required generated power of the fuel cell, calculates a torque command value of the air compressor based on the calculated rotational speed command value and current rotational speed of the air compressor, and controls rotational speed of the air compressor based on the calculated torque command value. The controller estimates the current rotational speed of the air compressor baaed on the measured value of the rotational speed acquired by the measured rotational speed acquirer and a history of the calculated torque command value, and calculates the torque command value by using the estimated rotational speed.
