Abstract
This application relates to a control system and method for use in a hybrid power supply apparatus comprising a current generating device, such as a fuel cell, and an energy storage device, such as a battery. The invention ensures that the fuel cell operates in a quasi steady state mode irrespective of fluctuations in load power demands. By restricting the operation of the fuel cell to discrete steady modes with minimal state changes, the useful service life of the fuel cell is prolonged. The control scheme ensures that the current generating device will run in a near steady mode even in the presence of a dynamic load.
