Patent ID: 6994276

Claim:
A device for mixing steam and hydrogen in fuel cell device in the form of a gas injection valve, mixing nozzle or jet compression nozzle, having a first fluid-carrying device ( 12 ) for carrying a first fluid in the form of hydrogen and a second fluid-carrying device ( 13 ) for carrying a second fluid in the form of steam, wherein the steam and hydrogen are mixed with one another in a mixing region ( 16 ) that is in communication with the fluid-carrying devices ( 12 , 13 ), and wherein a means ( 20 ) for generating turbulence in the applicable fluid and a heater, with which the fluid is heatable before reaching the mixing region ( 16 ), downstream of the means ( 20 ) for generating turbulence in terms of the flow direction of the applicable fluid are associated with at least one of the fluid-carrying devices ( 12 , 13 ).
