Abstract
A test system for testing a unit such as multiple solid oxide fuel cells. The test system includes a thermal test chamber in which a non-contact electrostatic voltage probe is mounted to scan the solid oxide fuel cells. The test system includes a detector coupled to the voltage probe to produce an output signal or display based on the measured voltages. The measured voltages are processed to compute a representative voltage for each fuel cell and to identify any defective fuel cells based on the measured voltages. The test system may be used during manufacture of solid oxide fuel cell stacks for cost effective testing to lower manufacturing costs.
