A liquid tank capable of detecting liquid level when the tank is rotated. The liquid tank includes an airtight vessel to store the liquid; and at least two electrodes installed inside the airtight vessel. The distal ends of the electrodes are positioned at a central volume of the airtight vessel. A fuel cell adopting the liquid tank maintains the liquid level in the tank near 50% of the full level even when the fuel cell is rotated.
