Abstract

An ion filter life perception device for a fuel cell vehicle is provided to detect a replacement life of a fuel cell ion filter cartridge. The device includes a body part that is installed within an ion filter and has an ion resin filled therein. A checker is disposed within the body part and has a varying position based on a volume of the ion resin. In addition, an elastic member is disposed between a first side end in the body part and the checker to push the checker within the body part by elasticity.

First claim

What is claimed is:

1. An ion filter life perception device for a fuel cell vehicle, comprising:
a body part installed in an ion filter and having an ion resin filled therein;
a checker disposed within the body part and having a varying position based on a volume of the ion resin; and
an elastic member configured between a first side end in the body part and the checker to push the checker within the body part in a predetermined push direction,
wherein the body part includes:
a mesh net member disposed between the checker and a second side end in the body part and filled with the ion resin; and
through holes perforated on a wall surface of the body part so that a cooling water penetrates through the mesh net member in a direction forming a predetermined angle with respect to the predetermined push direction.

2. The ion filter life perception device according to claim 1 , wherein a portion or the whole of the body part is formed to be transparent.

3. The ion filter life perception device according to claim 1 , wherein the checker is made of a fluorescent material.

4. The ion filter life perception device according to claim 1 , wherein the checker is formed to maintain air tightness between a circumference of the checker and an inside of the body part.

5. The ion filter life perception device according to claim 1 , wherein the checker identifies replacement timing of a cartridge of the ion filter and the body part is displayed with a moving position of the checker for replacement of the cartridge.

6. An ion filter life perception device for a fuel cell stack installed in a fuel cell vehicle, comprising:
a body part installed within an ion filter to be positioned on a cooling water channel of the fuel cell stack and having an ion resin filled therein;
a checker movably disposed within the body part and having a varying position based on a volume of the ion resin; and
an elastic member disposed between a first side end in the body part and the checker to push the checker within the body part by elasticity in a predetermined push direction,
wherein the body part includes:
a mesh net member disposed between the checker and a second side end in the body part and filled with the ion resin; and
through holes perforated on a wall surface of the body part so that a cooling water penetrates through the mesh net member in a direction forming a predetermined angle with respect to the predetermined push direction.

7. The ion filter life perception device according to claim 6 , wherein the body part is installed within the ion filter to be covered with an upper cap made of a transparent material and is identifiable from the exterior.
