Flexible fuel tank for fuel cell

Abstract

This invention is a flexible fuel tank for a fuel cell, including a sac body and a discharge port. The sac body that serves to store anode fuel is configured to a hollow configuration and made of a tactile material. The discharge port is provided to the sac body and serves to allow the anode fuel to flow therefrom.

1 . A flexible fuel tank for a fuel cell, including: 
 a sac body for storing anode fuel, configured to a hollow configuration and made of a tactile material; and    a discharge port, provided to the sac body, served to allow the anode fuel the discharge port to flow therefrom.    
   
   
       2 . The flexible fuel tank of  claim 1 , wherein the tactile material is made of a material selected from a silica gel, a plastic, or a metal foil coated with Teflon(R) surface coating.  
   
   
       3 . The flexible fuel tank of  claim 1 , wherein the anode fuel is a methanol solution.  
   
   
       4 . The flexible fuel tank of  claim 1 , wherein the flexible fuel tank further includes a non-return fitting connected to the discharge port.  
   
   
       5 . The flexible fuel tank of  claim 1 , wherein the sac body further includes an aperture for balancing the interior air pressure of the sac body and exterior atmospheric pressure so as to ensure smooth flowing of the anode fuel from the sac.  
   
   
       6 . The flexible fuel tank of  claim 1 , wherein the sac body is first partially filled with nitrogen and then filled with anode fuel.  
   
   
       7 . The flexible fuel tank of  claim 2 , wherein the metal foil is an aluminum metal foil.
