DRAINAGE APPARATUS FOR FUEL CELL SYSTEM GENERATION WATER

摘要

A drainage apparatus (15) for draining water within a fuel cell system, the fuel cell system having a fuel cell (1) for generating electric power by electrochemically reacting a fuel gas with an oxidizer gas. A water reserving device (16) reserves a generation water resulting from reacting the fuel gas with the oxidizer gas. A drainage flow path (L13, L 14) discharges the generation water within the water reserving device from an end opened to an outside of the water reserving device. An opening/closing valve (17) is installed in the drainage flow path. A pressure adjusting device adjusts an inner pressure of the water reserving device. A controller (30) controls the opening/closing valve and the pressure adjusting device, such that the controller controls the opening/closing valve from a closed state to an opened state, in a state of decompressing the inner pressure of the water reserving device by the pressure adjusting device when the fuel cell system is stopped.
