摘要： 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*).
