Abstract

A system for recovering gaseous dihydrogen produced in a distribution duct arranged between a main tank and a dihydrogen consumer device, the distribution duct comprising a pump. The system comprises: an auxiliary tank; a bypass duct, arranged between the distribution duct and the auxiliary tank, downstream of the pump; a valve arranged on the bypass duct; a module for obtaining a temperature of the dihydrogen in the distribution duct, upstream of the pump. A control module of the valve opens the valve when the temperature is greater than a predetermined value and closes the valve when the temperature is less than or equal to the predetermined value.
