PURGE CIRCUIT OF A FUEL CELL

摘要

A purging circuit for purging an anodic compartment of a cell of a fuel cell, this circuit including: a capacity, forming a related volume at least equal to 500 ml, for containing and homogenising a recovery gas, including an inlet and an outlet; a first nonreturn valve to prevent the recovery gas from returning through the outlet and allowing gas to flow from the first outlet to an inlet of the compartment; a second nonreturn valve to prevent gas from being discharged from the capacity through the inlet; a pressure sensor able to measure the pressure of a fluid present in the circuit; a valve controlling the flow of a supply gas to and from the compartment as a function of data of the sensor and allowing gas to flow from the first nonreturn valve to the inlet of the compartment.
