초록 ▼

A novel deionization filter for removing ions from a coolant in an electric fuel cell vehicle cooling system is disclosed. The deionization filter includes a filter housing having a coolant inlet port, through which the coolant enters the filter housing; and a coolant outlet port, through which the coolant exits the filter housing. An ion exchange bed having positively-charged and negatively-charged ion exchange resin beads is provided in the filter housing for removing negative and positive ions, respectively, from the coolant. At least one filter assembly is typically provided in the filter housing for filtering particles from the coolant.

1. In a vehicle having an electric fuel cell and coolant system, said coolant system including: a deionization filter including a housing having an inlet and an outlet, wherein a bed of negatively-charged cation and positively-charged anion exchange resin beads is contained within said housing, between the inlet and outlet;a pump;a thermal exchange device; anda coolant circulation network fluidically connecting said fuel cell, deionization filter, pump, and said thermal exchange device, said circulation network including: a coolant inlet line fluidically connected to said inlet; anda coolant outlet line fluidically connected to said outlet;the improvement comprising:a conductivity metering system including: an inlet conductivity meter provided in said coolant inlet line;an outlet conductivity meter provided in said coolant outlet line; anda conductivity analyzer box electrically connected to said inlet conductivity meter and said outlet conductivity meter for receiving signals from said meters;wherein, coolant is continuously circulated through said coolant system and through said deionization filter, where negative ions are removed from said coolant as it passes through said bed of negatively-charged cation and positively-charged anion exchange resin beads, the conductivity of coolant is measured before it enters said deionization filter using said inlet conductivity meter to obtain a first conductivity signal, the conductivity of coolant is measured after it exits said deionization filter using said outlet conductivity meter to obtain a second conductivity signal, and the difference in said first and second conductivity signals is computed in said conductivity analyzer box, to determine the functional efficacy of the deionization filter based on the difference in said first and second conductivity signals. 2. The vehicle of claim 1, wherein said deionization filter further comprises a first filter assembly provided adjacent to said inlet and a second filter assembly provided adjacent to said outlet. 3. The vehicle of claim 1, wherein said conductivity metering system further comprises a visual meter connected to said conductivity analyzer box. 4. The vehicle of claim 3, wherein said visual meter comprises an elongated indicator bar having a first segment indicating a condition requiring replacement of said ion exchange bed and a second segment indicating a condition comprising optimal operation of said ion exchange bed and an indicator needle responsive to indicate one of said first segment and said second segment based on said electrical conductivity difference.
