    摘要: A method of starting a fuel cell system and a fuel cell system including: a fuel cell stack having a phosphoric acid polymer electrolyte membrane, in which an electrochemical reaction occurs using hydrogen and oxygen; a cooling water circulating unit that supplies heated cooling water to the stack to increase the temperature of the stack; and an air circulating unit that provides heated air, as a source of the oxygen, to the stack. The circulating unit can include a heating unit to directly heat the air and/or a heat exchanger to heat the air using air exhausted from the stack. The temperature of the stack can be rapidly increased by supplying the heated air and by generating an endothermic reaction in the stack. The condensation of water vapor in the stack is repressed while the stack is heated, by the heating of the air and/or by increasing the pressure of the air.

    摘要: A method of starting a polymer electrolyte membrane fuel cell (PEMFC) stack by rapidly increasing its temperature. The PEMFC stack includes: a first flow line connected to cooling plates; a second flow line connected to the cooling plates; a coolant reservoir; a heat exchanger; a by-pass line; a heating element; a first valve installed between the first flow line and the heat exchanger; and a second valve that selectively connects the coolant reservoir, the second flow line, and the by-pass line. The method of starting a PEMFC stack includes: closing the first valve and controlling the second valve so that the second flow line and the by-pass line are connected to each other, and the coolant in the coolant reservoir is not connected to the second flow line and the by-pass line; and heating the coolant in the by-pass line.

    摘要: A fuel cell system includes a first heating structure that increases an internal temperature of the stack by passing exhaust gas of the process burner through the stack; and a second heating structure that increases the internal temperature of the stack by passing heated cooling water through the stack after the cooling water is heated by heat exchange with the exhaust gas of the process burner. Accordingly, when rapid heating of a stack is necessary like during a start up operation, a time required for the fuel cell system to reach a normal operation can be greatly reduced since the stack can be simultaneously heated using high temperature exhaust gas and heated cooling water.

    摘要: A fuel cell system a includes a cooling water temperature raising unit that raises the temperature of a fuel cell stack by passing discharge gas of a process burner or hydrogen gas of a fuel processing unit and cooling water that is heated by the discharge gas of the process burner through flow paths formed on opposing surfaces of cooling separators formed of a metal and installed between a plurality of cells in the stack. Thus in the fuel cell system, when the temperature of the stack needs to be rapidly raised, for example, during a start up operation of the fuel cell system, the temperature of the stack can be rapidly raised using discharge gas at a high temperature or combustion heat of hydrogen gas, and heated cooling water, and thereby, significantly reducing the time required for the fuel cell system to be in regular operation.
