摘要： A model uses various operating characteristics of a fuel cell to predict the relative humidity profile that is occurring within the fuel cell as a function of the reaction progress. The model is used to predict the relative humidity profile that will occur in response to changes to one or more of the operating characteristics of the fuel cell. A high frequency resistance of the fuel cell can also be used as a measure that is indicative of the humidity within the fuel cell. The model and/or the high frequency resistance can be used in a closed-loop feedback system to control the operation of the fuel cell to maintain the humidification of the MEA and fuel cells within a desired range to achieve a desired fuel cell performance.

摘要： A method for reducing the probability of an air/hydrogen front in a fuel cell stack is disclosed that includes closing anode valves for an anode side of the fuel cell stack to permit a desired quantity of hydrogen to be left in the anode side upon shutdown and determining a schedule to inject hydrogen during the time the fuel cell stack is shutdown.

摘要： A strategy of controlling a state of hydration of a fuel cell(s) and actively managing operation of the fuel cell(s) to achieve a desired state of hydration. The control strategy monitors the state of hydration and a rate of change of the state of hydration which are used to control the operation of the fuel cell(s). A supervisory control strategy is implemented that alters the operating parameters of the fuel cell(s) based upon the state of hydration, the rate of change of the state of hydration, and a desired operational range for the state of hydration.

摘要： A method and device for operating a fuel cell system. A recirculation loop coupled to a fuel cell cathode ensures that fluids passing through the cathode are recycled, thereby enabling reaction between residual oxygen in the recycled fluid and fuel that has been introduced into the recirculation loop until substantially all of the oxygen is reacted, leaving a substantially oxygen-free, predominantly nitrogen compound in the cathode and related flowpath. Thereafter, this compound can be redirected to purge the remaining residual hydrogen resident in the fuel cell's anode and related flowpath. While the present invention is usable during any period of system operation, it is especially valuable for operational conditions associated with starting up and shutting down a fuel cell system to inhibit the formation of high voltage potentials that could otherwise damage fuel cell catalysts or catalysts supports.

摘要： Processes to shut down a fuel cell system are described. In one implementation (300), a load (215) is cyclically engaged and disengaged across a fuel cell stack (205) so as to deplete the fuel available to the system's fuel cells (205). Voltage and/or current thresholds may be used to determine when to engage and disengage the load (215) and when to terminate the shutdown operation. In another implementation (500), a variable load (405) is engaged and adjusted so as to deplete the fuel available to the system's fuel cells (205). As before, voltage and/or current thresholds may be used to determine when to adjust the load (405) and when to terminate the shutdown process. In still another implementation, a load (215 or 405) may be periodically engaged and disengaged during some portion of the shutdown process and engaged but adjusted during other portions of the shutdown process.

摘要： A fuel cell system that includes an over-arching algorithm for providing a strategy that reduces relative humidity cycling of the cathode outlet gas between wet and dry operation to extend the useful life of the membrane. The algorithm receives sensor signals indicative of operating parameters of the fuel cell system. The algorithm maintains a cathode exhaust gas relative humidity in a wet operating mode if the operating parameters of the fuel cell system are able to sustain the cathode gas relative humidity above a first predetermined value, and maintains the cathode exhaust gas relative humidity in a dry operating mode if the operating parameters of the fuel cell system are able to sustain the cathode gas relative humidity below a second predetermined value.
