Abstract:
1. A fuel cell system comprising: a hydrogen generator configured to generate hydrogen by causing a reforming reaction to proceed using a material and water; a fuel cell configured to generate power by causing an electrochemical reaction to proceed using the hydrogen generated in said hydrogen generator and an oxidizing agent; a cooling water circulation portion configured to circulate water for cooling said fuel cell; a water condenser configured to condense water discharged from at least one of said hydrogen generator and said fuel cell; a water storage portion configured to store the water condensed by said water condenser; a water supply portion configured to take out the water from said water storage portion and to supply the water to at least one of said hydrogen generator, said fuel cell, and said cooling water circulation portion; a controller; and a water replenishment portion configured to replenish the water in said water storage portion from said cooling water circulation portion; wherein: said water storage portion is provided with a discharge port; and said controller is configured to perform control so that at least a part of the water in said water storage portion is discarded through the discharge port, and said water replenishment portion causes said cooling water circulation portion to replenish, in said water storage portion, water equal in amount to the at least a part of the water.
