Abstract

A fatty acid such as an acetic acid or a butyric acid is added to a fuel gas for a fuel cell as an odorant. This makes it possible to add an odor to the fuel gas without poisoning an electrode catalyst and an electrolyte, and to prevent the odor from remaining in an exhaust gas emitted from the fuel cell.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
         1 . A fuel gas for a fuel cell comprising: 
 a reaction gas that is supplied to a fuel cell and produces electricity by a chemical reaction; and    an odorant which is added to the reaction gas, is non-poisonous to an electrode catalyst and an electrolyte in the fuel cell, and dissolves in water so that an odor thereof disappears.    
     
     
         2 . The fuel gas for a fuel cell according to  claim 1  wherein: 
 the odorant is a fatty acid having an odor.  
 
     
     
         3 . The fuel gas for a fuel cell according to  claim 2  wherein: 
 the fatty acid is one of an acetic acid and a butyric acid.
