POWER SUPPLY CONTROL APPARATUS AND ELECTRIC DISCHARGE METHOD

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