Abstract
In a housing of a fuel cell are arranged an electromotive unit, a fuel tank, an anode passage through which the fuel is circulated between the electromotive unit and the fuel tank, an air supply section which supplies air to the electromotive unit, and a cathode passage through which products from the electromotive unit are discharged. The cathode passage has a first passage extending from the electromotive unit, branch passages which diverge from the first passage, a reservoir portion which communicates with the first passage and lower ends of the branch passages and is stored with water discharged from the first passage and water condensed in the branch passages, and a recovery passage which guides the water stored in the reservoir portion into the fuel tank. A radiator section is provided on the branch passages.
