Abstract
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.
Claims53
A liquid tank in a fuel cell system using a conductive liquid, comprising:
- an airtight vessel to contain the conductive liquid;
- and
- at least two electrodes installed inside the airtight vessel, the distal ends of the electrodes positioned at a central volume of the airtight vessel.
A liquid level detection device using a conductive liquid, comprising:
- at least two electrodes;
- and
- a signal detector to supply electricity to the electrodes and to detect a switching of the electrodes.
A tank to contain a conductive fuel for a fuel cell, comprising:
- a sealed housing;
- a first electrode having a first distal end;
- and
- a second electrode having a second distal end,
- wherein the first electrode and the second electrode extend to a central volume of the sealed housing to determine a level of fuel within the sealed housing, and the sealed housing is symmetrically disposed about the central volume.
A fuel cell system having a membrane electrode assembly, comprising:
- a fuel tank;
- and
- a signal detector,
- wherein the fuel tank contains a conductive fuel to the membrane electrode assembly, and comprises:
- a sealed housing;
- a first electrode having a first distal end;
- and
- a second electrode having a second distal end,
- wherein the first electrode and the second electrode extend to a central volume of the sealed housing to determine a level of fuel within the sealed housing, and the sealed housing is symmetrically disposed about the central volume,
- wherein the signal detector applies a weak current to the first and second electrodes to determine whether a circuit is completed by the conductive fuel.
