A fuel cell power system includes a fuel cell which has an optimal voltage; an energy storage device having a nominal voltage substantially similar to the optimal voltage of the fuel cell; and an electrical switch that, in operation, selectively electrically couples the fuel cell and the energy storage device to charge the energy storage device. A method includes providing a fuel cell having a nominal voltage; providing an energy storage device having a nominal voltage which is substantially similar to the nominal voltage of the fuel cell and electricall...
1. A fuel cell power system comprising: a fuel cell which, in operation, converts chemical energy into direct current electrical energy, the fuel cell being defined by a plurality of independently operable fuel cell sub-systems; a DC bus; a switching circuit electrically coupled with the fuel cell sub-systems and configured to independently selectively couple the fuel cell sub-systems to the DC bus; and an energy storage device electrically coupled with the DC bus and configured to be coupled to a load, and wherein the switching circuit select...
