Abstract
A charging device for a fuel cell includes a turbine having a housing part with a receiving chamber in which a turbine wheel of the turbine is received so as to be rotatable relative to the housing part about an axis of rotation. The turbine wheel includes impeller vanes via which a medium, in particular a gaseous waste gas of the fuel cell, can flow against the turbine wheel in an inlet region, and which are curved forwards at least in the inlet region.

A charging device for a fuel cell, wherein the fuel cell provides electric current for driving a motor vehicle, the charging device comprising:
- a radial turbine having a housing part with a receiving chamber in which a turbine wheel of the radial turbine is arranged so as to be rotatable relative to the housing part about an axis of rotation,
- wherein the turbine wheel comprises impeller vanes configured so that a gaseous waste gas of the fuel cell flows against the turbine wheel in an inlet region,
- wherein the impeller vanes of the turbine wheel are curved forwards in the inlet region and in a direction of a rotational direction of the turbine wheel.
