Abstract
Low conductivity cooling water for a fuel cell body is obtained by a water treatment apparatus which removes dissolved carbon dioxide gas in the exhaust gas condensate by a decarbonation column. Iron oxide is eliminated from the condensate as well as blowdown water by a MF membrane separator device. Iron ions are removed by a chelate resin column. Deionization occurs with an electrodeionizer which has an internal ion exchange resin.
