FUEL CELL SYSTEM, AND METHOD OF SEALING OXIDANT ELECTRODE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a structure of airtight sealing of a cathode of the fuel cell body while suppressing increase of the number of parts and increase of a parts mounting volume.

SOLUTION: A water permeation type humidifier 11 carries out humidification by moving moisture in exhaust air exhausted from an exhaust air outlet 3 of the fuel cell main body 1 to air to be supplied to an air inlet 5. A first open-close valve 47 is opened and closed between an air exhaust port 37 of the water permeation type humidifier 11 and the air inlet 5 of the fuel cell main body 1. A second open-close valve 49 is opened and closed between the exhaust air exit 3 of the fuel cell main body 1 and an exhaust air supply port 31 of the water permeation type humidifier 11. The first open-close valve 47 and the second open-close valve 49 are fixed to a coaxial driving shaft 43. By means that one driving motor 45 rotates the driving shaft 43, the first open-close valve 47 and the second open-close valve 49 are opened and closed simultaneously.
