Title:
FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/137142
Kind Code:
A1
Abstract:
It is possible to avoid a trouble caused by overvoltage of various elements to which an inverter voltage is applied. A control unit (8) judges whether a fuel cell (2) is generating electricity and an inverter voltage detected by a voltage sensor (V2) is equal to or above a predetermined upper limit voltage value. If yes, the control unit (8) reduces the duty ratio of an FC converter (3) and limits the output of the FC converter (3). This can suppress abnormal increase of the inverter voltage.
