METHOD FOR RELEASING EXHAUST GAS OF FUEL CELL GENERATING DEVICE, AND DEVICE THEREFOR

摘要

PURPOSE: To prevent the release of a white smoke-like exhaust gas and reduce the influence of moisture by decelerating and mixing the exhaust gas from a package having a fuel cell generating device collectively housed therein with air, and then releasing it to the outside air. CONSTITUTION: In a package 19 capable of being forcedly ventilated by a ventilating fan 22, the fuel gas rich in hydrogen generated in a fuel reformer 2 is supplied to a fuel cell 1 to generate a power. The air off gas 11 generated therein and the combustion exhaust gas 12 generated in the fuel reformer 2 are introduced into a generated water recovering device 3, and cooled to about 50-60 deg.C by a heat exchanger 3 to provide a recovered water 13. The exhaust gas 16 containing saturated steam therein is guided into a hatch 25 through an exhaust duct 24, and mixed with the air 17 blown out from the ventilating fan 22. Thus, a mixed exhaust air 18 reduced in steam concentration is formed and released to the outside air through a blowout hole 27.
