Liquid-gas separator for direct liquid feed fuel cell

A liquid-gas separator of a direct liquid feed fuel cell which receives liquid and gas from the direct liquid feed fuel cell and separates the liquid and gas, the liquid-gas separator comprising:

• a housing having open portion on the outer circumference thereof;
• a gas extracting membrane that covers the open portion and transmits only the gas;
• a liquid extracting membrane that defines a first chamber that is connected to the gas extracting membrane and a second chamber that is not connected to the gas extracting membrane, and selectively transmits the liquid in the first chamber to the second chamber, wherein the liquid extracting membrane and the first chamber surround the second chamber;
• an inlet that guides the liquid and the gas into the first chamber;
• and
• an outlet that is connected to the second chamber and guides the liquid in the second chamber to the outside.

A liquid-gas separator of a direct liquid feed fuel cell which receives liquid and gas from the direct liquid feed fuel cell and separates the liquid and gas, the liquid-gas separator comprising:

• a housing having one or more open portions on an outer boundary thereof,
• one or more gas extracting membranes, wherein each of the one or more open portions is covered by one of the one or more gas extracting membranes and wherein the one or more gas extracting membranes allow only gas to pass through from an interior of the housing to an exterior of the housing;
• a liquid extracting member that divides the interior of the housing into a first chamber that has a least one boundary that includes at least one of the one or more open portions covered by one of the one or more gas extracting membranes and a second chamber that does not have at least one boundary containing at least one of the one or more open portions covered by one of the one or more gas extracting membranes, and wherein the liquid extracting member selectively transmits the liquid in the first chamber to the second chamber and wherein the second chamber includes ion exchange beads;
• an inlet that guides the liquid and the gas into the first chamber;
• and
• an outlet that is connected to the second chamber and guides the liquid in the second chamber to the outside.
