DIRECT CONTACT TYPE CONDENSED WATER RECOVERING SYSTEM FOR FUEL CELL AND DIRECT CONTACT TYPE STEAM CONDENSER

摘要

PROBLEM TO BE SOLVED: To provide a direct contact type condensed water recovering system for a fuel cell and a direct contact type steam condenser which are economically compact and easy to maintain. SOLUTION: This system is provided with a fuel cell generating electric energy and thermal energy by reacting the hydrogen obtained when the raw fuel gas is reformed by a reformer 3 and the oxygen in the air, a decarbonating means 16 for removing carbon dioxide and a dephosphorylating means 21 for removing phosphoric acid in a condensed water storage section 24 below a direct contact type steam condenser 6 fed with the reformer combustion exhaust gas and air electrode exhaust gas of the fuel cell and recovering the moisture of the exhaust gas. The water stored in the condensed water storage section 24 is circulated between it and the direct contact type steam condenser 6 via a cooling tower 29, and water is recovered from the exhaust gas.
