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 control strategy results in a relative humidity profile that is substantially the same or constant regardless of the operational power level of the fuel cell stack. The strategy maintains the relative humidity profile within a range that enables high current density operation of the fuel cell stack. The profile is achieved by adjusting a coolant flow rate through the fuel cell stack to maintain a temperature change across the coolant flow path from inlet to outlet substantially constant regardless of the operational power level of the fuel cell stack.

摘要： A method of operating an electrochemical conversion assembly is provided. According to the method, an assembly warm-up operation is executed by increasing the temperature TSTACK of the membrane electrode assembly. Next, stoichiometry-based control of the relative humidity (RH) of one of the reactant flowfields is initiated when the temperature TSTACK exceeds a threshold temperature T0. The stoichiometry-based RH control comprises a reduction in the relative humidity from a value RHWET exceeding 100% relative humidity to a value RHDRY less than 100% relative humidity. The relative humidity value RHDRY is sufficiently low to permit reduction of an initial membrane hydration λWET in the membrane electrode assembly. The reduction in the relative humidity to RHDRY is achieved by controlling the stoichiometry of the reactant flowfield and the temperature of the membrane electrode assembly such that the reduction to RHDRY decreases substantially continuously, relative to portions of the RH profile of the reactant flowfield prior to initiation of the stoichiometry-based control. The cell transitions from the stoichiometry-based RH control to generally elevated-temperature, temperature-based RH control when membrane hydration in the membrane electrode assembly falls below a target membrane hydration value λDRY. Additional methods and corresponding systems are contemplated.

摘要： A system and method for determining whether an anode injector that injects hydrogen gas into an anode side of a fuel cell stack has failed. The method includes monitoring a voltage of the fuel cell stack and performing spectral analysis of the stack voltage to identify amplitude peaks in the stack voltage. The method further includes determining whether the spectral analysis of the stack voltage has identified an amplitude peak at a location where an amplitude peak should occur if the injector is operating properly. If no amplitude peak is identified at that location, then the method determines that the injector is not operating properly. If an amplitude peak is identified at that location, then the method compares the amplitude peak to the desired amplitude peak to identify if it is within a threshold to determine if the injector is operating properly.

摘要： A system for the slow purge of a fuel cell stack. A pump can be used to keep the coolant circulating, so that the stack, an associated radiator, and coolant plumbing therebetween are maintained at the same temperature. The heat from the stack, liquid coolant, and radiator can be used to provide the heat of vaporization of the liquid in the stack, and the liquid water can be removed from the stack as water vapor. Because the air flow rate is relatively low, there is sufficient time for the water to vaporize and for the air to come to the same temperature as the stack, which is also facilitated by high surface area for heat transfer. Purge air can be drawn into the stack through the radiator, via a purge air blower, which preheats the air to help avoid frigid air contacting the stack.
