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.

A device used to supply a gas mixture including hydrogen and carbon monoxide at a concentration not exceeding 100 ppm to a main fuel cell which is supplied with air. The device includes a reformer, which is used to convert a fuel into a gas mixture including carbon monoxide and hydrogen, and a purification device to diminish the concentration of carbon monoxide in the gas mixture and that is connected to an anode inlet of the main fuel cell. The supply device also includes an auxiliary fuel cell supplied with air and that receives the carbon monoxide produced by the reformer to convert part of the chemical energy of the carbon monoxide into electrical energy.
