1. A module for a dihydrogen supply system for an aircraft comprising a dihydrogen tank and an engine, said module comprising:
an outer box having an air inlet and an air outlet,
a leak-tight inner box, inert and housed in the outer box,
a pipeline configured to be fluidically connected between the dihydrogen tank and the engine, and passing through the outer box and the inner box,
a device housed in the inner box and configured to act on the dihydrogen circulating in the pipeline,
a first pressure limiter mounted on the pipeline in the inner box,
a second pressure limiter mounted on the inner box,
an exhaust pipeline fluidically connected between the first pressure limiter, the second pressure limiter, and outside of the module, the exhaust pipeline configured to be fluidically connected to outside of the aircraft when the module is installed in the aircraft,
an upstream shut-off valve mounted on the pipeline at an inlet of the pipeline in the outer box,
a downstream shut-off valve mounted on the pipeline at an outlet of the pipeline in the outer box,
detection means provided to detect a leak between the pipeline and the inner box or a leak between the inner box and the outer box and to deliver information representative of a leak, and
a control unit configured to control an opening and a closing of each of the upstream shut-off valve and the downstream shut-off valve as a function of the information delivered by the detection means.
