Abstract
An electric power supply device includes-a first energy source having at least one battery and a second energy source having at least one fuel cell. The first and second energy sources supply energy to an electric motor of a motor vehicle in different proportions. A control module of the electric power supply device includes a memory that stores a value of a maximum operating power able to be supplied by the second energy source so that the second energy source is not asked to supply an amount greater than the stored maximum operating power. The maximum operating power value of the second energy source is dependent on a cooling capacity for the second energy source.
