Abstract: 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.

Abstract: A fuel cell power plant (10) includes an oxidant stream controlled to enter a fuel cell (12) of the plant at a pressure of between about 0.058 pounds per square inch gas (‘psig’) and about 4.4 psig and the oxidant stream passes through the fuel cell (12) at an oxidant stoichiometry of between about 120% and about 180%, and preferably between about 150% and 170%. A macro-pore cathode gas diffusion layer (36) is secured between a cathode catalyst (16) and a cathode flow field (28). A porous coolant plate (44) is secured in fluid communication with and adjacent the cathode flow field (28). The gas diffusion layer (36) and coolant plate (44) facilitate removal of product water to eliminate flooding and to permit operation at low oxidant stoichiometry and high water balance temperature, thereby minimizing need for water capture and heat rejection apparatus.

Abstract: A control system for a fuel cell stack that controls the relative humidity of the cathode outlet gas during stack power transients to provide better cathode outlet gas relative humidity control by reducing the dynamic pressure range and thus the dynamic cathode outlet gas relative humidity range. In one embodiment, the control system uses a first narrower cathode pressure range based on stack current density during stack power transients to provide better cathode outlet gas relative humidity control, and uses a second wider cathode pressure range based on stack current density during low current density and steady-state current density to improve system efficiency by decreasing compressor parasitics.
