<P>PROBLEM TO BE SOLVED: To provide an air conditioning device for a fuel cell vehicle capable of performing heating by effectively using a total power of the vehicle while preventing the maximum output of a fuel cell from decreasing. <P>SOLUTION: When executing a heat pump heating mode, a first fuel consumption M1 is calculated that is the sum of fuel consumption necessary for maintaining the temperature of a fuel cell 2 at a standard fuel cell temperature or more and fuel consumption necessary for performing heating by a heat pump cycle. When executing a cooling water heating mode, a second fuel consumption M2 is calculated that is the sum of fuel consumption necessary for maintaining the temperature of the fuel cell 2 at the standard fuel cell temperature or more and fuel consumption necessary for performing heating using the heat of cooling water. When the first fuel consumption M1 is smaller than the second fuel consumption M2, the heat pump heating mode is determined to be executed. When the first fuel consumption M1 is larger than the second fuel consumption M2, the cooling water heating mode is determined to be executed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
