Fuel Cell System and Method for Operation of a Fuel Cell System

Abstract

The invention relates to a fuel cell system having at least one fuel cell ( 1 ) by means of which water is produced during operation, characterized by at least one atomizer apparatus ( 11 ), by means of which the water can be atomized into the environment. The invention also relates to a method for operation of a fuel cell ( 1 ).

1 . Fuel cell system having at least one fuel cell ( 1 ) by means of which water is produced during operation,
 characterized by   at least one atomizer apparatus ( 11 ) by means of which the water can be atomized into the environment.   
     
     
         2 . Fuel cell system according to  claim 1 ,
 characterized in that   the atomizer apparatus ( 11 ) is a nozzle.   
     
     
         3 . Fuel cell system according to  claim 1  or  2 ,
 characterized in that 
 the atomizer apparatus ( 11 ) is a two-material nozzle. 
 
     
     
         4 . Fuel cell system according to one of the preceding claims,
 characterized in that   the atomizer apparatus ( 11 ) is arranged in an off-gas line ( 6 ), which is associated with the off-gas path, of the cathode ( 3 ) of the fuel cell ( 1 ).   
     
     
         5 . Fuel cell system according to one of the preceding claims,
 characterized in that   the opening ( 15 ) of the atomizer apparatus ( 11 ) is arranged oriented upwards with respect to the ground ( 14 ) at an angle of more than 0° and less than 180°.   
     
     
         6 . Fuel cell system according to one of the preceding claims,
 characterized in that   the atomizer apparatus ( 11 ) is integrated in an outlet valve ( 10 ) which is arranged in the off-gas path.   
     
     
         7 . Fuel cell system according to one of the preceding  claims 1  to  6 ,
 characterized in that 
 the atomizer apparatus ( 11 ) is formed separately from an outlet valve ( 10 ) which is arranged in the off-gas path, and is arranged downstream from the outlet valve ( 10 ) in the off-gas path, in the flow direction of the off gas. 
 
     
     
         8 . Fuel cell system according to one of the preceding claims,
 characterized in that   the water that is produced is collected in one or more separators ( 13 ,  16 ), and is combined in the atomizer apparatus ( 11 ) for atomizing into the environment.   
     
     
         9 . Fuel cell system according to  claim 8 ,
 characterized in that   a separator ( 13 ,  16 ) is arranged in a supply line ( 5 ,  7 ) or in an off-gas line ( 6 ,  8 ) from the anode ( 2 ) or the cathode ( 3 ) of the fuel cell ( 1 ).   
     
     
         10 . Fuel cell system according to one of the preceding claims,
 characterized in that   the atomizer apparatus ( 11 ) has an associated separator ( 13 ,  16 ), and in particular is integrated in the separator ( 13 ,  16 ).   
     
     
         11 . Fuel cell system according to one of the preceding claims,
 characterized in that   the atomizer apparatus ( 11 ) opens into an off-gas line ( 6 ) which leads away from the cathode ( 3 ) of the fuel cell ( 1 ), in particular close to an output ( 61 ), which opens into the environment, of the off-gas line ( 6 ), and the water can be atomized into this off-gas line ( 6 ).   
     
     
         12 . Method for operation of a fuel cell system (I) having at least one fuel cell ( 1 ) which produces water during operation,
 characterized in that   the water is atomized into the environment by an atomizer apparatus ( 11 ).
