Patent ID: 7611794

Claim:
A water controller system constructed such that water generated from a cathode of a direct methanol fuel cell system and carbon dioxide and an unreacted methanol solution generated from an anode of the direct methanol fuel cell system are introduced into the water controller system, the carbon dioxide is discharged out of the water controller system, and the methanol solution is circulated to the corresponding electrode so as to reuse the methanol solution, wherein the water controller system comprises: a water inlet port, through which the water from the cathode is introduced into the water controller system, mounted at the upper part of the water controller system; a gas/solution inlet port, through which the carbon dioxide and the unreacted methanol solution generated from the anode are introduced into the water controller system, mounted below the water inlet port; a carbon dioxide outlet port mounted above the water inlet port; at least one methanol collecting unit, which is constructed such that, when a gas-phase ingredient, among ingredients introduced into the water controller system through the gas/solution inlet port, moves upward, the gas-phase ingredient passes through the water introduced into the water controller system through the water inlet port, mounted in a space defined between the water inlet port and the gas/solution inlet port, whereby the gas-phase methanol is prevented from being discharged out of the water controller system through the carbon dioxide outlet port, and a funnel-shaped condenser mounted below the carbon dioxide outlet port for condensing the evaporated water and the carbon dioxide passes through the funnel shaped condenser to the carbon dioxide outlet port, wherein the carbon dioxide outlet port is mounted at the upper end of the water controller system.
