The present invention relates to an apparatus for removing residual gas in a fuel cell. More specifically, the apparatus for removing residual gas to maintain a fuel cell effectively removes residual gas to prevent fire, explosion accidents, etc which may occur by residual hydrogen within a fuel cell system in a maintenance work of a fuel cell vehicle by absorbing residual hydrogen gas within the fuel cell system. According to the present invention, the apparatus for removing residual hydrogen gas to maintain a fuel cell is provided to effectively remove the residual hydrogen gas by making pressured air, which can be easily utilized in a service center, as a motive flow (primary flow), and making inner gas of the fuel cell system as an absorbing flow (secondary flow), by manufacturing the apparatus with a simple ejector structure in which a nozzle, a venturi, and a diffuser are combined in order or in which the nozzle and the venturi are combined. |
