description Disclosed is a method for controlling a pressure regulating valve (6) for regulating the internal pressure (Pint) of a fluid circuit (3) in an electrochemical device (2), said fluid circuit (3) being fed by a compressor (4) drawing air at an external pressure (Pext) and compressing same at the internal pressure (Pint) according to a compression ratio (A); said method comprises a step of measuring the external pressure (Pext), determining an internal pressure set point (Pint*) on the basis of the external pressure (Pext) measured and the compression range (B), so as to promote overall efficiency (R1) of the electrochemical device (2) and the compressor (4) according to the internal pressure (Pint) and the compression ratio (A), and a step of controlling the pressure regulating valve (6) so as to reach the internal pressure set point (Pint*). Un procédé de commande d'une vanne de régulation (6) de la pression interne (Pint) d'un circuit de fluide (3) dans un dispositif électrochimique (2), ledit circuit de fluide (3) étant alimenté par un compresseur (4) prélevant l'air à une pression externe (Pext) et le comprimant à la pression interne (Pint) selon un taux de compression (A), ledit procédé comportant une étape de mesure de la pression externe (Pext), de détermination d'une pression interne de consigne (Pint*) à partir de la pression externe (Pext) mesurée et de la plage de compression (B), pour favoriser un rendement global (R1) du dispositif électrochimique (2) et du compresseur (4) prédéterminé en fonction de la pression interne (Pint) et du taux de compression (A), et une étape de commande de la vanne de régulation (6) pour atteindre la pression interne de consigne (Pint*).
