Abstract
An apparatus for measuring a methanol concentration is provided. The apparatus is located in a pipe which supplies liquid fuel to the anode of a direct liquid feed fuel cell, and may include a vertical supporting beam located in the pipe; a horizontal plate located on the supporting beam and having an upper surface with a predetermined roughness; and a sensor fixed to a side of the supporting beam, which generates an electrical signal through a transformation of the supporting beam resulting from variations in a viscosity of the liquid fuel running through the pipe.

An apparatus for measuring a methanol concentration, located in a pipe which supplies liquid fuel to the anode of a direct liquid feed fuel cell, the apparatus comprising:
- a vertical supporting beam located in the pipe;
- a plate located on the supporting beam and having an upper surface with a predetermined roughness;
- and
- a sensor fixed to a side of the supporting beam, which generates an electrical signal through a transformation of the supporting beam resulting from variations in a viscosity of the liquid fuel running through the pipe.
An apparatus for measuring a methanol concentration, located at a pipe which supplies liquid fuel to the anode of a direct liquid feed fuel cell and has a first opening, the apparatus comprising:
- a housing having a second opening corresponding to the first opening in its top, and fixed to an outside of the pipe by aligning the second opening with the first opening;
- a supporting beam having one end fixed to a bottom of the housing penetrating through the second opening, separated from the first opening and the second opening;
- a plate fixed to the other end of the supporting beam and having an upper surface with a predetermined roughness;
- and
- a sensor fixed to a side of the supporting beam, which generates an electrical signal through the transformation of the supporting beam resulting from variations in a viscosity of the liquid fuel running through the pipe.
