    Abstract: A fuel cell system includes a fuel cell stack, a fuel gas supply channel, a fuel gas circulation channel, a circulating pump that is driven by a pump motor having no rotation detecting sensor, and an ECU. When a method for operating the fuel cell system determines that the circulating pump is frozen in a low-temperature environment, the method performs a first step of performing a brake mode to limit the rotation of the pump motor while passing current to the pump motor, to thereby heat the pump motor. The method further performs a second step of, after rotating the pump motor, determining that the circulating pump has unfrozen if the rotational speed of the pump motor exceeds a given value.

  • Patent number: 11056699
    Abstract: In a fuel cell system, the output from a plurality of fuel cells can reach an output greater than or equal to auxiliary driving power in a short time because the initial supply amount of raw fuel supplied from a raw fuel supply part is greater than or equal to a first supply amount that is a raw fuel supply amount corresponding to the auxiliary driving power. Thus, even if the raw fuel is supplied at the initial supply amount when a power failure has occurred in an electric power system during a startup operation of the fuel cell system, it is possible to supply electric power from the fuel cells to the auxiliary machinery and continue to drive the auxiliary machinery under the control of a startup controller. This suppresses the stop of the fuel cell system under the startup operation.

  • Patent number: 11038186
    Abstract: A system for controlling operation of a reformer for fuel cells is provided. When the temperatures of a high temperature reforming unit operating as an endothermic catalyst reactor and a CO modification unit operating as an exothermic catalyst reactor deviate from catalyst activity reference temperatures, an amount of water supplied for heat exchange is increased so that the water for heat exchange sequentially flows up to the CO modification unit and the high temperature reforming unit. Accordingly, the temperature of the high temperature reforming unit and the temperature of the CO modification unit reach the catalyst activity reference temperatures, thereby preventing deterioration of high-concentration hydrogen production efficiency and unnecessary CO removal efficiency of the reformer and improving lifespan of catalysts of the reformer.
