Beschreibung
Zusammenfassung:	The step-up converter includes the plurality of converting units, each having the reactor and the semiconductor element part having electronic parts such as the transistor and the diodes. The ECU performs changeover control of increase or decrease of the number of drive phases of the converting units, based on the output condition from the fuel cell, the temperature condition of the reactor, and the temperature condition of the semiconductor element part.
