NOVELTY - The fuel cell system (300) comprises a fuel cell stack (2) including fuel cells having anodes and cathodes, a suction device (310) present in fluid communication with an anode supply manifold and/or an anode exhaust manifold, and a first purge valve (214) present in fluid communication with the anode supply manifold, a second purge valve (216) present in fluid communication with the anode exhaust manifold and/or an anode outlet valve (212) present in fluid communication with the anode exhaust manifold. The fuel cell stack has an anode supply manifold and an anode exhaust manifold.    USE - The fuel cell system is useful in an internal-combustion engine of modern vehicles or electric vehicles.    ADVANTAGE - The fuel cell system ensures efficient and rapid system start-up with minimal stack degradation by optimizing the hydrogen-air front time during the start-up, and minimizes hydrogen emissions.    DETAILED DESCRIPTION - The fuel cell system (300) comprises a fuel cell stack (2) including fuel cells having anodes and cathodes, a suction device (310) present in fluid communication with an anode supply manifold and/or an anode exhaust manifold, and a first purge valve (214) present in fluid communication with the anode supply manifold, a second purge valve (216) present in fluid communication with the anode exhaust manifold and/or an anode outlet valve (212) present in fluid communication with the anode exhaust manifold. The fuel cell stack has an anode supply manifold and an anode exhaust manifold present in fluid communication with the anodes. The suction device is: placed in fluid communication with the first purge valve, the second purge valve and/or the anode outlet valve; adapted to selectively draw a partial vacuum on the fuel cell stack during a start-up of the fuel cell system; and an eductor having a motive port, a discharge port and a suction port. The anode supply manifold and/or the anode exhaust manifold is present in fluid communication with the suction port of the eductor. The motive port of the eductor is placed in fluid communication with a motive flow generator that is an air compressor. The air compressor present in fluid communication with a flow restrictor that is a filter. A reduced pressure zone is formed between the air compressor and the flow restrictor, when the air compressor is in operation.
