FUEL CELL CARTRIDGE

摘要

A fuel cell cartridge for containing fuel for fuel cells, comprising a polyester resin, wherein after the fuel is contained and preserved at 60°C for one week, a change of density at the bottom portion and the mouth portion is 0.01 g/cm 3 or less. Even when methanol of a high concentration is contained, the fuel cell cartridge maintains excellent appearance effectively preventing the occurrence of whitening in the container and, particularly, at the mouth portion and the bottom portion thereof, and effectively suppressing a decrease in the shock resistance.
