Abstract:
A fuel cell having a membrane electrode assembly to cause an electrochemical reaction in a fuel so as to generate electric power, a fuel holding body for holding the fuel to supply the fuel to the membrane electrode assembly, a fuel supply path to supply the fuel being pressurized to the fuel holding body and a fuel exhausting path to exhaust the fuel from the fuel holding body by using an internal pressure of the fuel.
Abstract:
A fuel cell system is provided which can constantly control a fuel concentration of a liquid fuel supplied to a fuel cell, such as a DMFC. A DMFC system comprises a high-concentration cartridge in which a methanol aqueous solution having a concentration higher than a target fuel concentration is sealed, a water cartridge in which water is sealed, a mixing tank for mixing the methanol aqueous solution from the high-concentration cartridge with the water from the water cartridge to prepare the methanol aqueous solution having the target fuel concentration, and the DMFC for generating electricity by being supplied with the methanol aqueous solution from the mixing tank and air.
