Abstract
A lightweight and inexpensive solid polymer electrolyte fuel cell having a simple structure wherein a stack is efficiently cooled to be able to cope with a high output density. Fuel gas flows through a fuel gas flow path provided in the stack while flowing air as an oxidizing agent through air reactive gas flow path to generate electric power. An air cooling gas flow path is provided inside the stack. Water is added to air fed from an air feed blower with a water feed unit. Humidified air flows through the air cooling gas flow path, and then flows through the air reactive gas flow path. Discharged air is cooled in a condenser to condense water, and the resulting condensed water is recirculated to the water feed unit.
