FUEL CELL POWER SYSTEM, METHOD OF DISTRIBUTING POWER, AND METHOD OF OPERATING A FUEL CELL POWER SYSTEM.

摘要

A fuel cell power system (10), comprising a fuel cell (16) which generates D.C. voltage while operating; an ultracapacitor (14) which, in operation, is electrically coupled with a load (58) and has a voltage condition; and a circuit (22) which, in operation, electrically couples and decouples the fuel cell to the ultracapacitor based upon the voltage condition of the ultracapacitor.
