Title
(DE) ELEKTRISCHER TURBOLADER ZUR LUFTVERSORGUNG EINER BRENNSTOFFZELLE
(EN) ELECTRIC TURBOCHARGER FOR SUPPLYING AIR TO A FUEL CELL
(FR) TURBOCOMPRESSEUR ÉLECTRIQUE ASSURANT L'ALIMENTATION EN AIR D'UNE PILE À COMBUSTIBLE
Abstract
(DE) Die Erfindung betrifft einen elektrischer Turbolader (13) zur Luftversorgung einer Brennstoffzelle (3), mit einer Turbine (16), einem Kompressor (12) und einer elektrischen Maschine (17), welche alle in Triebverbindung miteinander stehen, mit einer kompressorseitigen Einrichtung zur Beeinflussung von Druck und/oder Volumenstrom am Kompressor (12), und mit einer turbinenseitigen Einrichtung zur Beeinflussung von Druck und/oder Volumenstrom an der Turbine (16). Die Erfindung ist dadurch gekennzeichnet, dass die kompressorseitige Einrichtung zur Beeinflussung von Druck und/oder Volumenstrom am Kompressor (12) als variable Kompressoreingangsgeometrie (18) ausgebildet ist.
(EN) The invention relates to an electric turbocharger (13) for supplying air to a fuel cell (3), having a turbine (16), a compressor (12) and an electric machine (17) which all have a drive connection with one another, having a compressor-side device for influencing pressure and/or volume flow at the compressor (12), and having a turbine-side device for influencing pressure and/or volume flow at the turbine (16). The invention is characterized in that the compressor-side device for influencing pressure and/or volume flow at the compressor (12) is constructed as a variable compressor inlet geometry (18).
(FR) L'invention concerne un turbocompresseur électrique (13) assurant l'alimentation en air d'une pile à combustible (3). Ledit turbocompresseur électrique comprend une turbine (16), un compresseur (12) et un moteur électrique (17) qui sont tous en liaison d'entraînement les uns avec les autres, ainsi qu'un dispositif côté compresseur agissant sur la pression et/ou le flux volumique au niveau du compresseur (12) et un dispositif côté turbine agissant sur la pression et/ou le flux volumique au niveau de la turbine (16). L'invention est caractérisée en ce que le dispositif côté compresseur agissant sur la pression et/ou le flux volumique au niveau du compresseur (12) est réalisé sous la forme d'une entrée de compresseur à géométrie variable (18).
