SOLID POLYMER ELECTROLYTE TYPE FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a solid polymer electrolyte type fuel cell system highly efficiently recovering heat energy of oxidized gas to be exhausted and water contained in the oxidized gas. SOLUTION: This solid polymer electrolyte type fuel cell system is so constituted that an air feeder, a humidity exchange type heat exchanger, an oxidization side water cooler and condenser and an oxidization side air cooler and condenser in a channel for feeding air as oxidizing agent to the fuel cell.
