Direct methanol fuel cell system, fuel cartridge, and memory for fuel cartridge

Abstract

A fuel cartridge to be connected to a direct methanol fuel cell power generating device includes a spare fuel tank which stores a liquid fuel and is to be connected to the direct methanol fuel cell power generating device and a harmful substance trap member. The spare fuel tank stores a liquid fuel and is to be connected to the direct methanol fuel cell power generating device. The harmful substance trap member is fixed to the spare fuel tank and is to be connected to the direct methanol fuel cell power generating device. The harmful substance trap member contains a harmful substance trap material which traps gaseous harmful substances exhausted from the direct methanol fuel cell power generating device.

1 . A fuel cartridge to be connected to a direct methanol fuel cell power generating device, comprising: 
 a spare fuel tank which stores a liquid fuel and is to be connected to the direct methanol fuel cell power generating device; and    a harmful substance trap member which is fixed to the spare fuel tank and to be connected to the direct methanol fuel cell power generating device, and the harmful substance trap member containing a harmful substance trap material which traps gaseous harmful substances exhausted from the direct methanol fuel cell power generating device.    
   
   
       2 . The fuel cartridge of  claim 1 , further comprising a memory fixed to the spare fuel tank, and stores at least one of information about the spare fuel tank and information about the liquid fuel.  
   
   
       3 . The fuel cartridge of  claim 1 , wherein the harmful substance trap member includes a trap material container having a gas exhaust port, a gas diffusion passage which is formed in the trap material container, and a gas diffusion hole opened in a wall of the gas diffusion passage, and the harmful substance trap material is filled in a space between the inner side of the trap material container and the wall of the gas diffusion passage.  
   
   
       4 . The fuel cartridge of  claim 1 , wherein the liquid fuel is a methanol aqueous solution.  
   
   
       5 . The fuel cartridge of  claim 1 , wherein the liquid fuel is a methanol aqueous solution having a concentration of a range of 95% or more to less than 100%.  
   
   
       6 . The fuel cartridge of  claim 1 , wherein the harmful substance trap material includes at least one powder of active carbon and silica gel.  
   
   
       7 . The fuel cartridge of  claim 1 , wherein the harmful substance trap material includes active carbon.
