DRAINING MEANS FOR A FUEL CELL SYSTEM AND RELATED ADJUSTMENT MODE

摘要

The invention relates to a draining device for a fuel cell (FC). The effluents from a hydrogen FC comprising a recirculation circuit have to be regularly drained in order to guarantee optimum operation. The draining devices of the prior art are characterized by significant variations in the hydrogen concentration of the effluents. The invention consists in incorporating the draining means in the device for separating the liquid and gas phases of the effluents. Advantageously, means for fine regulation of the draining flow rate are provided, which makes it possible to limit the losses of hydrogen the drained effluents.
