L'invention concerne un ensemble turbomachine (100) conçu pour un système de pile à combustible (150) pour un véhicule (200a), en particulier un véhicule utilitaire (200b), comprenant une turbomachine à plusieurs étages (50) comportant un carter (51), deux étages (52, 53), chacun des étages (52, 53) étant conçu pour la compression et/ou l'expansion de l'air (40) traversant l'étage (52, 53), les étages (52, 53) comprenant un rotor (54) monté de manière à pouvoir tourner autour d'un axe (A), et un ensemble tuyauterie (60) disposé à l'extérieur du carter (51) pour relier par conduite de fluide les deux étages (52, 53) ou pour relier par conduite de fluide les étages (52, 53) et l'ensemble pile à combustible (10) du système de pile à combustible (150), et un composant électronique de puissance (70) relié électriquement à la turbomachine (50). Cette invention est caractérisée en ce que le composant électronique de puissance (70) est disposé dans une direction radiale (R) entre le carter (51) et l'ensemble tuyauterie (60), et en ce que le composant électronique de puissance (70) et l'ensemble tuyauterie (60) sont disposés de manière à se chevaucher au moins par endroits dans une direction circonférentielle (U).
