HYDROGEN INJECTION MODULE AND SUPPLY CIRCUIT PROVIDED WITH SAID MODULE

The present invention relates to a hydrogen injection module, intended for circulating a hydrogen flow rate in a supply circuit for fuel cells, comprising a main housing formed by a tubular body defining a longitudinal axis (L), said main housing being provided with an inlet and an outlet, between which and following a forward flow direction there is a particle filter member, a first safety shut-off solenoid valve and a second flow rate-regulating solenoid valve spaced apart from each other and housed in corresponding bores made in the main housing that run perpendicular to the longitudinal axis of the main housing, the first and second solenoid valves being in fluid communication with each other through a first passage channel having an angle of inclination with respect to the longitudinal axis (L) of the main housing, such that an inlet end of the first passage channel, which corresponds to the flow outlet point of the first solenoid valve, is located at a level below the outlet end of the first passage channel, which corresponds to the flow inlet point to the second solenoid valve.
