Abstract
A direct methanol fuel cell (DMFC) system including: a separator receiving a gas-liquid mixture discharged from a stack and separating the mixture to gas and a liquid; a methanol cartridge storing high concentration methanol; and a fuel mixer for methanol dilution. The separator and the fuel mixer are separate structures, each including an agitator for stirring a liquid. The agitators can be on the same rotation axis.
Claims16
A direct methanol fuel cell (DMFC) system comprising:
- a stack generating electricity through a reaction using methanol and oxygen;
- a separator receiving a gas-liquid mixture discharged from the stack and separating the mixture into a gas and a liquid;
- a methanol cartridge storing high concentration methanol;
- and
- a fuel mixer having a separate space divided from the separator, mixing high concentration methanol supplied from the methanol cartridge with the liquid supplied from the separator in the separate space, and diluting the mixture to low concentration methanol to be applied to the stack.
