Abstract

Disclosed are a fuel cell vehicle and a method of controlling the same. The fuel cell vehicle includes a battery, a cell stack configured to provide stack voltage, a load connected to the battery and the cell stack, a multiphase converter configured to adjust a voltage range between the cell stack and the battery and including first to N(where N is a positive integer of 2 or greater) current paths connected to the cell stack and connected in parallel to each other, and a main controller configured to control the multiphase converter to allow alternating current to sequentially flow through the first to Ncurrent paths when measurement of the impedance of the cell stack is required.
