PROBLEM TO BE SOLVED: To provide an electrical power system that includes a fuel battery as an energy source, and is large in not only energy density, but also output density and also adaptive to large variation in power consumption through simple means.SOLUTION: In an electric power system 10, a fuel battery 1 is connected to an input terminal of a DC/DC converter 2, and a lithium ion secondary battery 3 and a load 4 are connected to an output terminal in parallel. The electric power system includes voltage measuring means 6 measuring the terminal voltage of the secondary battery 3 and a control computer 5 which sets a target output voltage of the converter 2, the target output voltage being set to a little higher than the terminal voltage. The fuel battery 1 is placed in operation under power generation conditions for the best fuel conversion efficiency. Consequently, a system comprising the fuel battery 1 and converter 2 functions like a constant-voltage/current source which outputs electric power generated by the fuel battery 1 at a voltage equal to the terminal voltage of the secondary battery 3. A difference between the output current and a current for driving the load 4 is adjusted automatically through charging/discharging of the secondary battery 3.
