  • Patent number: 7887962
    Abstract: A fuel cell system and its control method capable of removing condensed water only from a place where flooding is generated, without deteriorating an electrolyte membrane. The electrolyte membrane (10) which is a solid high-molecular membrane is sandwiched by an anode (12) and a cathode (14) and these are sandwiched by collectors (16). Furthermore, these are sandwiched by separators (18), thereby constituting a fuel cell (30). Heating means is arranged on the separator (18) and its switch (20) is turned ON when the moisture for hydration of the electrolyte membrane (10) is condensed, so that current is supplied to the heating means from a power source (22) so as to evaporate the condensed water. This rapidly eliminates flooding.
