Abstract: A system and method for controlling the voltage on a high voltage bus in a fuel cell system in response to a failed high voltage battery. The method includes determining if the high voltage battery has failed, and disconnecting the battery from the high voltage bus in response to a failure. The method measures the voltage of the fuel cell stack by a DC boost circuit and converts the measured voltage to a voltage set-point value that sets the voltage on the high voltage bus, where the voltage set-point value changes as the measured voltage changes. A supervisory controller sets the media flow to the fuel cell stack and determines a minimum stack voltage limit value based on the stack maximum current draw that is used to determine a high voltage bus lower limit value.

Abstract: A fuel cell system or HVDC power source includes a fuel cell or DC power source having a high voltage direct current (HVDC) bus including y-capacitors, which connect the HVDC bus terminals to chassis or safety ground, and a fault current discharge compensation circuit interconnected with the HVDC bus. A monitoring circuit monitors a fault discharge current of the Y-cap circuit and generates a fault signal when the fault current occurs based on a rate of change of a voltage of the Y-cap circuit. A switching circuit redirects the majority of the fault discharge current.

The bipolar plates of the fuel cell stack are equipped with a specialized tab connector that engages with a corresponding electrical connector on the cell voltage unit. Either the tab connectors on the bipolar plates or the corresponding connectors on the cell voltage unit include flexible members to provide a suitable electrical friction engagement. The cell voltage unit is attached to the bipolar plates and does not require its own separate housing.

Abstract: A fuel cell system that employs a matched battery that matches the battery voltage to a fuel cell power bus voltage so as to eliminate the need for a DC/DC converter. The internal characteristics and parameters of the matched battery allow it to operate over the large load dependent voltage swing of the fuel cell, and prevent the battery state of charge from going below a damaging value. The battery type, number of battery cells and the battery internal impedance are selected to provide the desired matching. In one embodiment, the battery is a lithium ion battery. The system also includes a diode electrically coupled to the power bus line and a by-pass switch electrically coupled to the power bus line in parallel with the diode. The by-pass switch is selectively opened or closed to allow the fuel cell stack to recharge the battery and prevent the battery from being overcharged.

Abstract: A fuel cell assembly having a terminal plate that is isolated from fluid flows passing to the fuel cell stack through manifolds is provided. A corrosion resistant member is positioned between the fuel cell stack and the terminal plate and sealingly engages with the manifold. The sealing engagement between the manifold and the corrosion resistant member prevents fluid flowing through the manifold to the fuel cell stack from contacting the terminal plate. Thus, a fuel cell assembly according to the present invention can be operated while preventing a fluid flow through the manifold from contacting the terminal plate.

Abstract: A drive system for a compressor that delivers compressed air to a fuel cell system in a motor vehicle. The drive system includes an electric motor that drives the compressor. During normal operation of the fuel cell system, the motor is fed with electrical energy from the fuel cell system. During start-up of the fuel cell system, the electric motor receives electrical energy from a low voltage battery, where the electric motor can be operated at a voltage that is significantly higher than the output voltage of the low voltage battery. An expander can be connected to the compressor to drive the compressor with energy from cathode exhaust gases. Further, hydrogen recirculation can also be employed.

Abstract: A fuel cell system includes a fuel cell having conductive coolant flowing there through and a high voltage direct current (HVDC) bus interconnected with the fuel cell. An active isolation circuit includes coolant fault current sensors that detect a fault current (also called residual current) in the coolant and generates a fault signal when the fault current is detected. A switching circuit compensates and redirects the fault current based on the fault signal, providing active fault current limitation thereby.
