    Abstract: A fuel cell stack includes a first stack including a plurality of first fuel cells stacked on each other, and a second stack including a plurality of second fuel cells stacked on each other and disposed on one side of the first stack. Each of the first stack and the second stack includes a fuel inlet hole, through which fuel to be supplied to anodes of the respective first and second fuel cells is introduced, a fuel discharge hole, through which the fuel passing through the anodes is discharged, an air inlet hole, through which air to be supplied to cathodes of the respective first and second fuel cells is introduced, and an air discharge hole, through which the air passing through the cathodes is discharged. The fuel cell stack divided into the two stacks increases a charging ratio of hydrogen at the anodes of the respective stacks.

    Abstract: A fuel cell apparatus may include a stack, a stack air blower configured to supply external air to the stack, a humidifier configured to extract moisture contained in exhaust air and to supply the extracted moisture to external air supplied to the stack, a first bypass channel configured to allow exhaust air to bypass the humidifier, a first three-way valve controlled to adjust the amount of exhaust air that bypasses the humidifier, and a humidity sensor configured to sense the humidity of external air. The fuel cell apparatus may also include a second bypass channel configured to allow external air to bypass the humidifier, a second three-way valve controlled to adjust the amount of external air that bypasses the humidifier, and a controller configured to control the first three-way valve and the second three-way valve depending on the sensed humidity value of the external air.

    Abstract: A fuel reforming device includes a combustion part including a burner; an exhaust part configured to circulate an exhaust gas that is generated from the combustion part; and a reactor that is configured to generate hydrogen from a raw material by absorbing heat from the exhaust gas circulating in the exhaust part. The reactor includes a heat storage member that is configured to absorb the heat from the exhaust gas during operation of the combustion part, store the absorbed heat, and provide the absorbed heat to the reactor.
