FUEL CELL SYSTEM

A fuel cell system (10) includes a target pressure value for the pressure in a fuel cell (1) is set depending on a demand output value to the fuel cell (1). A turbine (3c) retains a set pressure line (L1) representing a relationship between an airflow rate (qb) supplied to the turbine (3c) and a pre...

Zusammenfassung:	A fuel cell system (10) includes a target pressure value for the pressure in a fuel cell (1) is set depending on a demand output value to the fuel cell (1). A turbine (3c) retains a set pressure line (L1) representing a relationship between an airflow rate (qb) supplied to the turbine (3c) and a pressure ratio of a pressure upstream of the turbine (3c) to a pressure downstream of the turbine (3c). A controller (9) executes a first control when the target pressure value for the fuel cell (1) is lower than the set pressure line (L1) and executes a second control when the target pressure value for the fuel cell (1) is higher than the set pressure line (L1). In executing the second control, the controller (9) controls an outlet valve (5v) so as not to be fully opened when a turbine bypass valve (7v) is fully closed.
