Abstract

PILE A COMBUSTIBLE ET PROCEDE DE PURGE La pile à combustible (10) comprend : - un contrôleur programmable, - une cathode (20) avec un conduit d’entrée de fluide (40), un conduit de sortie de fluide (50) et un conduit de bipasse (60) entre le conduit d’entrée et le conduit de sortie, le conduit de bipasse (60) comprenant une première valve (70) contrôlable par le contrôleur. Le contrôleur est programmé pour mettre en œuvre un procédé de purge de la cathode (20), ledit procédé comprenant : - une première étape durant laquelle la première valve (70) est ouverte, - une deuxième étape (190) suivant la première étape, durant laquelle la première valve (70) est fermée. Figure pour l'abrégé : 2FUEL CELL AND PURGING METHOD The fuel cell (10) comprises: - a programmable controller, - a cathode (20) with a fluid inlet conduit (40), a fluid outlet conduit (50) and a bypass conduit (60) between the inlet conduit and the outlet conduit, the bypass conduit (60) comprising a first valve (70) controllable by the controller. The controller is programmed to implement a process for purging the cathode (20), said process comprising: - a first step during which the first valve (70) is open, - a second step (190) following the first step, during which the first valve (70) is closed.
