AI Technical Summary

Technical Problem

Ion filters in fuel cell systems face constraints on placement due to head positioning requirements, leading to issues such as excessive cooling water loss or bubble trapping, increased weight, and cost, along with difficulties in cartridge replacement.

Method used

The ion filter is integrated into the fuel cell stack as a modular unit, featuring a manifold section and ion filter section with a detachable cartridge assembly, a lid for easy access, and a valve to prevent coolant leakage, reducing the need for separate hoses and simplifying the structure.

Benefits of technology

This design overcomes placement constraints, facilitates easy cartridge replacement, reduces weight and cost, and enhances the efficiency of coolant flow by integrating the ion filter within the stack, minimizing coolant loss and bubble formation.

Abstract

The present invention relates to an ion filter for a fuel cell stack, and more specifically, to an ion filter having a simplified structure that overcomes the head constraint of the ion filter in a fuel cell system. The ion filter according to the present invention comprises: a manifold portion configured to branch cooling water introduced from the outside; and an ion filter portion connected to the manifold portion, into which cooling water is introduced from the manifold portion, and comprising a cartridge assembly containing an ion filter resin inside.
