: METHOD AND APPARATUS FOR IMPROVING THE PERFORMANCE OF A FUEL CELL ELECTRIC POWER SYSTEM
Application 2299/KOLNP/2005 published 2007-03-30, filed 2005-11-17
Current pulsing improves the performance of fuel cells in a fuel cell stack based power system. Voltage clamping limits the voltage peaks that occur after a current pulse. In a hybrid power system, an electric storage device supplies the loads during current pulsing. The electric storage device may sink current to achieve the voltage clamping, and/or power system may employ other the voltage clamping circuits. (FIG.4)
