Dual power source switching control

摘要

A system and method for controlling or otherwise effectively managing cell voltage degradation in the operation of a fuel cell device comprises inter alia a fuel cell (110) in parallel electrical connection with a secondary power source (145) and an automated controller (155) for switching between power supplied from the fuel cell (100) and the secondary power source (145). Disclosed features and specifications may be variously adapted or optionally modified to control or otherwise optimize the rate of cell voltage degradation in any fuel cell system. Exemplary embodiments of the present invention may be readily integrated with other existing fuel cell technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.
