摘要： Provided is an integrated structure of an ion filter and a reservoir according to an embodiment of the present disclosure. An integrated structure of an ion filter and a reservoir includes a reservoir storing coolant for cooling a fuel cell stack, an ion filter located inside the reservoir, and a control valve located inside the reservoir to be opened or closed so that the coolant flows into the ion filter, in which the reservoir is divided into a first region in which the ion filter is located by opening or closing the control valve and a second region that is a space other than the first region, and the first region and the second region are connected by an air vent unit through which air passes.

摘要： An electrocardiogram (ECG) measurement device for a vehicle is provided. The ECG measurement device includes an impedance compensator that corresponds to an electrode in contact with a body of a driver and configured to compensate an impedance of each of electrode signals received from the electrode. An electrode selector sequentially selects the electrode signals in response to receiving the electrode signals from the electrode. A differential amplifier differentially amplifies the electrode signals. In particular, each electrode signal has the compensated impedance. Additionally, a signal quality evaluator evaluates quality of an ECG signal output from the differential amplifier and a compensation controller then adjusts an impedance compensation value of each of the impedance compensators as a result of evaluating the quality of the ECG signal.
