A fuel cell the gas-liquid separation apparatus and methods of operation that directly uses methanol as a fuel

The gas-liquid separating device for the fuel used in direct methanol fuel cell DMFC (direct methanol fuel cell) is disclosed. Disclosed DMFC separation apparatus comprises a housing that is accommodated in the gas-liquid mixture recovered from the stack, can rotate within the housing to the rotor and, installed, including a motor for rotating the rotor, when the rotor is rotating the liquid of the gas-liquid mixture is the housing by the centrifugal force toward the outside of the driven gas is characterized in that the phase separation to occur molryeoseo toward the center of the housing. The gas-liquid separation apparatus having such a structure, because it performs gas-liquid separation by centrifugal force according to the forced rotation there is no need to match a particular port and the direction of gravity and location may be employed from time to time even passable changing mobile device, also, with time because it does not use a membrane according to this rapidly degraded maintain the smooth functioning is guaranteed even during prolonged use. DMFC, the gas-liquid separation, centrifugal
