Abstract: An injector of a fuel cell system operates when the output amount of a fuel cell is in a first output region, and a linear solenoid valve operates when the output amount of the fuel cell is in a second output region. When the output amount of the fuel cell is in a third output region that is included in the second output region, the linear solenoid valve opens at such a degree that fuel gas and fuel off-gas necessary to secure a hydrogen amount threshold that is a smallest hydrogen amount necessary for operation of the fuel cell are capable of being introduced from an ejector into the fuel cell.

Abstract: This method for detecting a hydrogen leak applies to a fuel cell system (10) comprising a fuel cell (12); a hydrogen supply system (30) comprising a reservoir (32) and the supply circuit (34) connecting the reservoir to the anode compartment (16) of the fuel cell and comprising an ejector (36) of Venturi type; a recirculation circuit (60) for recirculating unconsumed hydrogen between the anode compartment of the cell and the Venturi-type ejector (36), the recirculation being driven by the Venturi-effect ejector. The method comprises steps involving calculating the total flow rate of hydrogen consumed; calculating the flow rate of hydrogen admitted to the ejector; determining the leak rate as the difference between the flowrate of hydrogen admitted and the total flow rate of hydrogen consumed; and detecting a potential leak of hydrogen by comparing the leak rate against at least a threshold value, such that the method detects all of the hydrogen leaks that occur in the system downstream of the ejector.

Abstract: An electric vehicle includes a battery and one or more solid oxide fuel cells. A fuel line provides fuel to the solid oxide fuel cell from a first chamber of a fuel tank. An exhaust line returns exhaust fluid from the solid oxide fuel cell to a second chamber of the fuel tank. A refrigeration system is in thermal communication with the exhaust line to remove heat from and condense the exhaust fluid before the exhaust fluid enters the fuel tank.

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 disclosed in the present specification includes a fuel cell stack, a fuel pipe to supply fuel to the fuel cell stack, and a pressure sensor to measure pressure in the fuel pipe. The fuel pipe includes an outer pipe and an inner pipe inserted through the outer pipe. A gap between the outer pipe and the inner pipe is sealed at two locations in a longitudinal direction of the fuel pipe. A first through-hole is provided in an upper part of the outer pipe between the two locations, and a second through-hole is provided in a lower part of the inner pipe between the two locations. The pressure sensor is attached to the first through-hole.
