Fuel cell performance requires adherence to a variety of specifications, so test engineers must conduct a series of characterization, performance and durability tests. Fuel cells are characterized by determining their resistance. Fuel cell performance is usually indicated via polarization curves by measuring its voltage and current. A durability test is the test after a fuel cell stack reaches operating conditions, the stack is subjected to a continuous series of charge/discharge cycles to ensure that it will work safely and reliably in the field.
