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.
Claims7
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.
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.
