FUEL CELL SYSTEM

摘要

A fuel cell system provided with a fuel cell and a secondary cell as power supply sources for a load. During normal operation, a first control unit causes a first converter (fuel cell side-boost converter) to control the output voltage of the fuel cell, and also a second control unit causes a second converter (secondary cell side-boost converter) to control the output voltage to a first load side. However, if an abnormality occurs in the secondary cell, the first control unit causes the first converter to control the output voltage, and also the second control unit causes the second converter to control the output voltage to a second load side.
