Abstract
A fuel cell system comprising a fuel cell having plural membrane-electrode assemblies and plates, fuel and oxidant humidifiers and heater exchanger. Heat exchange between a supply inlet and discharge outlet is carried out between first and second heat exchange mediums. Fuel gas and oxidant gas are directed to flow parallel to each other in the fuel cell. A circulation path is established through the fuel and oxidant humidifiers and the heat exchanger by interconnection among discharge outlet, heat exchanger, fuel and oxidant humidifiers, and inlet.
