Purge circuit of a fuel cell

Abstract : The present application concerns a purge circuit (40) of an anode compartment (14) of a cell (2) of a fuel cell (1), said circuit comprising: - means (20), forming an associated volume at least equal to 500 ml, in order to contain and homogenise a waste gas, comprising a first inlet (24A) and a first outlet (24B); - a first non-return valve (42) connected to the first outlet (24B) to contain a waste gas, in order to prevent a gas from entering said means (20) via the first outlet (24B) and allow a portion of a gas to flow from the first outlet (24B) towards an inlet of the compartment (14); - a second non-return valve (44) connected to the first inlet (24A), in such a way as to prevent a gas from being discharged from said means (20), via the first inlet (24A); - a pressure sensor (50) designed to measure the pressure of a fluid present in said circuit; - means (48) allowing or preventing the flow of a feed gas of said compartment (14) to the inlet of same, depending on data from said sensor (50), and allowing gas to flow from the first non-return valve (42) to an inlet of the compartment (14).
