Abstract: A hybrid fuel cell plant includes a fuel cell and a fuel reformer that mixes a hydrocarbon fuel and steam together upstream of the fuel cell. The reformer partly or fully converts the hydrocarbon fuel and steam into a reformed fuel stream that includes hydrogen (H 2 ), carbon monoxide (CO) and carbon dioxide (C0 2 ). The fuel cell receives the reformed fuel stream at or above atmospheric pressure and also an air stream at or above atmospheric pressure that includes oxygen (0 2 ) and nitrogen (N 2 ) to generate a fuel cell hot exhaust stream that includes lean air, unoxidized CO and residual H 2 . The lean air stream has an 0 2 molar fraction less than that of the fuel cell inlet air. The hot exhaust stream is generated above atmospheric pressure when the reformed fuel and air stream are received by the fuel cell above atmospheric pressure. An internal or external combustion engine directly or indirectly generates power in response to the pressurized fuel cell hot exhaust stream to increase the efficiency of the fuel cell power plant. A Rankine cycle generates power in response to waste heat extracted from at least one of the fuel cell hot exhaust stream and hot exhaust gas generated by the combustion engine to further increase the efficiency of the hybrid fuel cell plant from 50% to above 70% efficiency.

Abstract: A controller, in electrical communication with the one or more of the injectors and a high-pressure fuel pump, generates a first signal responsive to which the valve in the injector opens or closes and a second signal responsive to which the high-pressure fuel pump increases or decreases the pressure level in the fuel accumulator. The system may also include one or more sensors to detect a pressure within the air manifold and to detect the pressure within the fuel accumulator The controller is programmed to calculate an in -cylinder gas pressure. When the engine is operating at a maximum engine load and the in -cylinder gas pressure readies or exceeds a maximum pressure limit, the controller transmits one or more signals to adjust the fuel injection timing and/or adjust the pressure in the fuel accumulator to maintain NOx and fuel consumption within acceptable limits. The engine is for a locomotive.
