1. A fuel cell system comprising:
a first fuel cell having an electrode area made of first electrode material; and
a second fuel cell having an electrode area made of second electrode material having low durability against output voltage variation in comparison with the first electrode material,
the fuel cell system being configured to supply electrical power to a load,
the fuel cell system further comprising:
a required electrical power acquisition unit configured to obtain required electrical power of the load; and
a control unit configured to control the second fuel cell in a manner that a variation of output electrical power of the second fuel cell becomes equal to or less than a predetermined limit variation, and control the first fuel cell in accordance with the required electrical power and output electrical power of the second fuel cell.
