<P>PROBLEM TO BE SOLVED: To provide a fuel cell system with high operation efficiency without giving rise to physical troubles, by matching output current/output voltage characteristics at a fuel cell side and maximum output characteristics at a load side. <P>SOLUTION: In output power/output voltage characteristics of a fuel cell, a fuel cell system can obtain optimum output power (=P<SB POS="POST">M</SB>) by outputting system voltage (=V<SB POS="POST">M</SB>), shown at an intersection (B-point) of a graph shown by maximum output characteristics f2 of an FC and a graph shown by maximum output characteristics f3 of a load device, to a DC-DC converter as output voltage of the fuel cell. <P>COPYRIGHT: (C)2013,JPO&INPIT |
