Moisture-generating device for a fuel cell, and method for operating a moisture-generating device

A moisture-generating device (10) for generating a moisture-enriched air flow or gas flow, said device comprising:

• a housing (H) having a main extension direction (HR) and an inflow region (2) and an outflow region (3), wherein a gas or air flow is generated between the inlet region (2) and the outlet region (3) at least in regions along the main extension direction (HR), and having a lateral inlet region (EB) which extends at a specified angle to the main extension direction (HR), and having a mixing region (MB) which extends inside the housing (H) at least partially along the main extension direction (HR);
• a water injector (WI) which is located in the lateral inlet region (EB) and by which atomized water can be introduced into the mixing region (MB) at the specified angle with or counter to the main extension direction (HR), wherein the gas or air can be mixed with the atomized water in the mixing region (MB);
• a separator grid (SG) which is located in the mixing region (MB) and through which the gas or air flow mixed with the atomized water can flow, and
• a homogenizing region (HB) which adjoins the mixing region (MB) in the main direction of extension (HR), and the separator grid (SG) is located between the mixing region (MB) and the homogenizing region (HB), and wherein a degree of moisture of the gas or air flow in the homogenizing region (HB) can be homogenized at least in certain regions, wherein the outflow region (3) closes off the homogenizing region (HB) in the main extension direction.
