MEASUREMENT DEVICE FOR TESTING A FUEL CELL STACK

摘要

A measurement device for measuring voltages along a linear array of voltage sources, such as a fuel cell stack, includes at least one movable voltage probe that measures voltage transitions along an array element. The measured voltage is used to determine a distance of travel of the at least one voltage probe along the fuel cell stack from the speed of the probe and the timing of the transitions.
