Muffler

Abstract

The muffler includes a sound-absorbing structure ( 1 A, 1 B) having a gas introduced from a fuel cell ( 100 ). The muffler includes an outlet ( 13 ) defined by the sound-absorbing structure for discharging a drain separated from the gas.

What is claimed is:  
     
         1 . A muffler comprising: 
 a sound-absorbing structure having a gas introduced from a fuel cell; and    an outlet defined by the sound-absorbing structure for discharging a drain separated from the gas.    
     
     
         2 . The muffler according to  claim 1 , 
 wherein the sound-absorbing structure has expansion chambers separated from each other,    wherein one of the expansion chambers has an inlet for introducing the gas, and    wherein the outlet is located at said one of the expansion chambers.    
     
     
         3 . The muffler according to  claim 1 , 
 wherein the sound-absorbing structure includes a remover configured to remove moisture from the gas.    
     
     
         4 . The muffler according to  claim 3 , 
 wherein the sound-absorbing structure has an inlet for introducing the gas, and    wherein the remover comprises, 
 a tube enclosing the inlet and having a first hole through the tube in a radial direction; and  
 a wall located opposing the inlet and closing off the tube in an axial direction.  
   
     
     
         5 . The muffler according to  claim 4 , 
 wherein the tube is configured in a cylindrical shape.    
     
     
         6 . The muffler according to  claim 2 , 
 wherein the expansion chambers include a partition between the expansion chambers, and    wherein the partition defines a second hole for the expansion chambers to communication with each other through the second hole.    
     
     
         7 . The muffler according to  claim 6 , 
 wherein the second hole is located at a lower half portion of the partition in a vertical direction.    
     
     
         8 . The muffler according to  claim 1 , 
 wherein the outlet connects with another tube.
