FUEL CELL STACK

摘要

PURPOSE: A fuel cell stack is provided to be able to detect operation state and suitability of configuration of a unit cell from current density and temperature of a sensed unit cell, by using fuel cell state measurement units. CONSTITUTION: A fuel cell stack comprises a separator(20) equipped in a unit cell composing a fuel cell stack, and fuel cell state measurement units(30) installed in the separator, in order to sense the current density and the temperature of the unit cell. At least one or more fuel cell state measurement unit is uniformly installed in the separator to sense whole unit cell. The fuel cell state measurement unit is formed to replace a part of a protrusion(52) in a channel part(50) arranged in the separator, for facilitating fluid flow in the separator, and is formed to have same height with the protrusion.
