Beschreibung
Zusammenfassung:	The module (1) has compressors (18, 21) delivering oxygen-rich gas to a fuel cell (2) e.g. alkaline fuel cell. An oxygen-rich gas purification device is arranged in upstream and/or downstream of the compressors. The device has electrostatic filters (14, 23) e.g. cyclone filter, with electrodes that are supplied by electrical units and produce plasma containing ionic or radical compounds from organic compounds in the gas. A photo catalytic material is provided on downstream of the electrodes, and mineralizes organic compounds, and the ionic/radical compounds contained in the plasma. An independent claim is also included for a method for purifying oxygen-rich gas for a motor vehicle. L'invention concerne un module de puissance 1, notamment pour véhicule automobile, comprenant une pile à combustible 2 alimentée en gaz riche en hydrogène et en gaz riche en oxygène, des moyens de compression (18, 21) capables de délivrer à la pile à combustible 2 le gaz riche en oxygène et un dispositif de purification du gaz riche en oxygène disposé en amont et/ou en aval des moyens de compression (18,21). Le dispositif de purification comprend :- au moins deux électrodes alimentées par des moyens électriques et capables de produire, à partir des composés organiques contenus dans le gaz riche en oxygène, un plasma contenant des composés ioniques ou des radicaux, et- un matériau catalytique capable de minéraliser :les composés ioniques ou les radicaux contenus dans le plasma etles composés organiques.
