| description | A power supply control apparatus (100) includes a switching control device (101) configured to switch each of switching elements (223, 225) of a power converter (22), and a discharge control device (102) configured to, when residual charge of the fuel cell is being discharged, control a gas supply unit (41) such that oxidant gas is not supplied to the fuel cell, in a first period, control the switching control device (101) such that an on time during which at least one switching element is maintained in an on state is longer than the on time during an operation of the fuel cell (12) and the at least one switching element is switched between the on state and an off state alternately, and in a second period, control the switching control device (101) such that the at least one switching element continues to maintain the on state. |
