FUEL CELL PROTECTION CIRCUITS

摘要

A fuel cell protection circuit comprises an overvoltage sensor 46 monitoring the fuel cell output voltage; a protective load 44; and a load connecting means 42 responsive to an overvoltage signal for connecting the protective load 44 to the fuel cell 22 when the fuel cell output voltage reaches a predetermined level to limit an overvoltage excursion of the fuel cell by providing a current path for the fuel cell output.
