Fuel cartridge for fuel cells, fuel cell, fuel cell power system and method of mounting a fuel cell cartridge on a fuel cell

摘要

The present invention aims at providing a fuel cell and a fuel cartridge in which a fuel contained in the fuel cartridge is determined to be appropriate for the fuel cell or not, and when it is appropriate, the connection of the fuel cartridge is mechanically made possible. A fuel cartridge for a fuel cell is provided with a specific member for distinguishing the methanol concentration of a contained methanol solution fuel according to the methanol concentration. Further, a fuel cell is provided with a concentration recognizing member for determining whether the member for distinguishing the fuel concentration provided at the fuel cartridge is the one for a desired concentration.
