A boost converter (14) is provided with a plurality of conversion units (31a-31d), each of which is provided with a semiconductor element unit that is provided with electronic components, such as a reactor (32), a transistor (33a) and diodes (33b, 34b). An ECU (41) performs switch control for increasing/reducing the drive phase number of the conversion units (31a-31d) on the basis of conditions of output from a fuel cell (12), temperature conditions of the reactor (32), and temperature conditions of the semiconductor element units. |
