Cartridge for methanol fuel cell

Abstract

Disclosed is a small-sized, light-weighted, low-cost cartridge for methanol fuel cells which has excellent permeation-preventing performance (barrier properties) against methanol and oxygen. This cartridge is suitably used as a fuel tank or refill container for a direct methanol fuel cell (DMFC). Specifically disclosed is a cartridge for methanol fuel cells comprising at least one methanol impermeable layer having a methanol vapor permeability coefficient of not more than 15 μg·mm/m2·hr at 40° C. The methanol impermeable layer of the cartridge is preferably made of a cyclic olefin resin, a polyester resin, a resin coated with an inorganic film or the like.
