Apparatus comprising a device for regulating a concentration of dihydrogen

An apparatus containing at least one of a dihydrogen tank or a dihydrogen circuit, the apparatus comprising a device for regulating a concentration of dihydrogen which comprises:

• at least one pair of electrical conductors as well as at least one controller and which is located outside the tank and/or the circuit,
• each pair of electrical conductors comprising a first electrical conductor and a second electrical conductor, the first electrical conductor and the second electrical conductor of each pair being spaced apart by a predetermined distance, and
• the at least one controller being configured to repeatedly command an application of a predetermined voltage difference between the first electrical conductor and the second electrical conductor so that, based on said predetermined distance, an electric arc of controlled power is formed between the first electrical conductor and the second electrical conductor,
• wherein the at least one controller is connected to at least one optical sensor and the at least one controller is configured to receive a signal originating from the at least one optical sensor, to analyze this signal so as to detect a possible presence of a spectral line corresponding to a combustion of dihydrogen and to transmit a warning signal to a signaling system of the apparatus upon a detection of such a spectral line.
