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.

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： 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 thermal management system of an electrochemical engine comprises a radiator provided with a wicking mechanism, a coolant pump fluidly connected to the radiator, a water tank, and a water pump. The water tank is located in the void spaces around fuel storage tanks, and may be filled directly or with reclaimed water from a vapor by-product of the electrochemical engine. The water pump is operable to supply water from the water tank to the wicking mechanism during peak power and/or hot day conditions. Moisture in the vapor by-product may be condensed with the excess cooling capacity of the radiator under less severe cooling conditions. Under freezing conditions, exhaust or coolant from the electrochemical engine may be used to unfreeze water in the tank and wicking mechanism supply lines.

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 a reduced voltage level across the fuel cell is achieved. Attainment of the reduced voltage level indicates that the recycled fluid is substantially oxygen-free, yielding an inerting fluid. Thereafter, this compound, followed by air, or air directly can be used to purge the fuel cell's anode and related flowpath during system shutdown. Similarly during system startup, hydrogen can then be introduced into the fuel cell's anode and then air into the cathode and related flowpath for normal operation. The placement of a purge valve allows the anode to be purged with air without re-introducing air into the cathode.
