  • Direct methanol fuel cell system
    Publication number: 20060222923
    Abstract: A direct methanol fuel cell system is constructed to sit stably and to minimize external influences of impacts on a fuel cell stack. The fuel cell system includes an aqueous solution tank for storing a methanol aqueous solution, a fuel tank for storing a methanol fuel to be supplied to the aqueous solution tank, and a fuel cell stack supplied with the methanol aqueous solution from the aqueous solution tank for generating electric energy through electrochemical reactions. The fuel tank and the aqueous solution tank are disposed above the fuel cell stack.
