Abstract
Provided is a warm-up apparatus for a fuel cell for an electrically driven vehicle in which a fuel cell and a secondary battery are mounted as power sources of a motor for travelling, and which, when charging of the secondary battery is required, stops operation of the fuel cell and charges the secondary battery with electric power from an external power source by means of a battery charger. The warm-up apparatus includes: a secondary battery cooling circuit that cools the secondary battery; a fuel cell cooling circuit that cools the fuel cell; a connection passage that connects the secondary battery cooling circuit and the fuel cell cooling circuit through a switching valve; and a warm-up control unit that, during charging of the secondary battery, controls the switching valve so that the secondary battery cooling circuit and the fuel cell cooling circuit communicate through the connection passage.
