Title: FUEL CELL SYSTEM AND CONTROL METHOD OF FUEL CELL SYSTEM
Abstract:
A fuel cell system (100) is provided with a stack (11), an air blower (12), a fuel burner (21), and a controller (31). An air blower (12) is installed on the upstream side of a cathode (11a) of the stack (11) to supply air to the cathode (11a). The fuel burner (21) is installed between the air blower (12) and the cathode (11a) to heat the air output from the air blower (12). When the stack (11) starts, the controller (31) controls the supply to the cathode (11a) of air heated by the fuel burner (21) and the temperature increase in the stack (11). Furthermore, until the stack (11) reaches the specified target output or the target temperature after the stack (11) reached the temperature enabling power generation, the controller (31) controls at least one of (a) the control for setting the excess oxygen factor of air output from the combustion burner (21) lower than the excess oxygen factor at the target output of the stack, (b) the control for setting the output voltage of stack (11) in the specified range, and (c) the control of heating by the combustion burner (21).
