Abstract
A power source system () includes a fuel cell () and a battery () connected in parallel. A DC-DC converter () is connected to the battery () side. A maximum output ratio of the fuel cell () and the battery () is set in a range in which the output of the fuel cell falls within 65 to 80% of the total output. Accordingly, electric power loss due to the DC-DC converter () is controlled, whereby a high energy efficiency can be achieved.
