摘要： A voltage monitoring system for measuring the voltage of the fuel cells in a fuel cell stack that employs optical devices for providing an optical signal of the measured voltages, where one or more of the fuel cells power the optical devices. A surface mount device is electrically coupled to opposing plates in the stack, or opposing plates over a plurality of cells in the stack. The surface mount device includes a bonded contact and a spring contact to provide the electrical connection. A detector is positioned remote from the stack that receives the optical signals and converts them back to electrical signals indicative of the voltage.

摘要： A fuel cell system that employs a technique for reducing or significantly eliminating the MEA degradation that occurs as a result of the hydrogen-air front in the anode flow channels at system start-up. After system shut-down, any hydrogen remaining within the anode flow channels will be quickly reacted or diffused. At the next start-up, a switch is closed to provide a dead short across the positive and negative terminals of the fuel cell stack as hydrogen is being introduced into the anode flow channels. The existing air in the cathode flow channels reacts with the hydrogen being introduced across the membrane in the normal fuel cell reaction. However, the short prevents a voltage potential across the membrane.

摘要： A system for oxidizing contaminants on both the cathode and anode electrodes in a fuel cell stack by applying a suitable voltage potential across the electrodes that causes the oxidation. The system includes a battery and an electrical converter electrically coupled to the battery. The electrical converter is configured to assist in providing an oxidation potential to the fuel cell stack by converting electrical power from the battery at a time effective to oxidize contaminants on the cathode or anode electrodes in the stack. The electrical converter provides a positive potential to the fuel cell stack to oxidize contaminants on the cathode electrodes and provides a negative potential to the fuel cell stack to oxidize contaminants on the anode electrodes. If the battery is a high voltage battery, then the converter is a power converter and if the battery is a low voltage battery, then the converter is boost converter.

摘要： A control system for delivering a constant fuser temperature despite variations in the line voltage is effected by a control circuit which employs closed loop feedback control to control the rms voltage across the load. This is accomplished by a circuit and method which functionally provides a continuous solution to the equation which describes the relationship between the temperature of the fuser and the temperature of a desired control setpoint. Briefly, the solution of this equation is obtained by monitoring, i.e. sampling, the temperature of the fuser, subtracting the desired control temperature, and then integrating the difference over time. The resultant time integral is used to control the operating point of a pulse width modulated power controller. The integrator has a time constant sufficiently long and the power controller operates at a frequency sufficiently high so as to render lighting flicker imperceptible. The control circuit is particularly advantageous in controlling the rms voltage across a radiant fuser lamp in an electrostatographic printing machine.

摘要： A fuel cell system is provided that includes a fuel cell stack with a plurality of fuel cells and a power converter in electrical communication with the fuel cell stack. The power converter is configured to selectively regulate a power of the fuel cell stack and short circuit the fuel cell stack, as desired. A method for starting the fuel cell stack is also described, including the steps of causing a short circuit of the fuel cell stack by placing the power converter in a short circuit mode; introducing a hydrogen to the anodes of the fuel cell stack to displace a quantity of air on the anodes; and placing the power converter in a power regulation mode. A degradation of the fuel cell stack during start-up is thereby militated against.
