Abstract
An ion exchange filter apparatus to reduce ions contained in a liquid medium used in a fuel cell system is equipped with an ion exchange filterto receive an ion exchange resin. The ion exchange filterincludes a flow passageto introduce the liquid medium to the ion exchange resin, a bypass passageto flow the liquid medium by bypassing the ion exchange resin, and an orificedisposed at a branch section where the bypass passageis branched from the flow passage, to determine a flow volume ratio of the liquid medium flowing in the ion exchange resinand the bypass passage, wherein a hole diameter of the orifice is set so that a pressure loss generated when all the amount of the liquid medium flows in the bypass passagebecomes substantially equal to an allowance maximum pressure loss of the ion exchange filter
