Abstract: A fuel cell that includes specially configured bipolar plates that separate the reactant gas flow field in an active area of the fuel cell into a primary flow channels and a secondary channels. In one embodiment, the primary flow channels are in use over the entire operating range of the fuel cell and the secondary flow channels are only in use at high cell current outputs. At low power demands, the primary channels operate at a voltage below 0.8 volts and provides a gas current density of more than 0.2 A/cm2. The secondary flow channels have no gas supply and operate at mass transport limited conditions. Because of this design, voltage cycling is significantly reduced or eliminated, thus increasing the life of the fuel cell.

Abstract: A fuel cell system that employs a fuel cell stack and a supplemental power source, such as a battery or an ultra-capacitor. The power source provides supplemental power in addition to the output power of a fuel cell stack for high load demands. The fuel cell system includes a power management controller that controls the power output from the supplemental power source and the fuel cell stack as the demand on the fuel cell stack changes. During low load demands, where the voltage across the fuel cell stack may increase above a potential that could cause oxidation of platinum catalyst particles within the fuel cells in the stack, the power management controller causes the fuel cell stack to charge the power source so as to decrease the voltage output on the stack.

Abstract: A valve seat especially adapted for a high performance butterfly valve is characterized by flexing axially rather than stretching radially when the seat interfaces with a closure member. In the preferred form, a seat has a support member embedded therein to provide restorative forces which tend to urge the valve seat to a predetermined position in response to axial flexing.

Abstract: A method for reconditioning a fuel cell stack. The method includes periodically increasing the relative humidity level of the cathode input airflow to the stack to saturate the cell membrane electrode assemblies to be greater than the relative humidity levels during normal stack operating conditions. The method also includes providing hydrogen to the anode side of the fuel cell stack at system shut down while the membrane electrode assemblies are saturated without stack loads being applied so that the hydrogen crosses the cell membranes to the cathode side and reacts with oxygen to reduce stack contaminants.
