<P>PROBLEM TO BE SOLVED: To provide an ion exchange resin filter system which selectively removes cations and anions in water to be treated, and improves durability of an installed fuel cell system, and the like. <P>SOLUTION: This ion exchange resin filter system comprises an ion removal unit 3 accommodating a cation exchange resin filter 9 and an anion exchange resin filter 10 separately, a flow regulation means (a three-way valve) 6 for regulating the flow ratio of the water to be treated flowing through each of the filters 9, 10 of the ion removal unit 3, a pH sensor 7 for detecting the pH value of the water to be treated, and a controller 8 for sending a control signal to the flow regulation means 6 based on the pH value detected from the pH sensor 7 to regulate the flow ratio of the water to be treated. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
