HYBRID HYDROGEN FUEL CELL COMBUSTOR POWER SYSTEM

A fuel cell electrical power generation system is described herein. The system uses a combustor to increase the pressure and temperature of exhaust gases from a fuel cell stack of the system. The combustor uses hydrogen from a hydrogen supply to provide fuel to the combustor. The increased temperature/pressure of the exhaust gases post combustion are used to rotate a turbine, which in turn rotates a compressor of a turbocharger. The compressor compresses incoming air to increase the power output and/or the efficiency of the system. An ebooster can be used in low load conditions, such as during a startup or during at time in which the electrical loading on the fuel cells is relatively low.
