Fuel cell diagnostics

A suite of many different diagnostic approaches have been developed to study fuel cells for performance, durability, and component fimctionality [25]. These include electrochemical, electrical, chemical, and mechanical tests, both on an operating fuel cell and in ex situ measurements. Some of the most commonly used in situ tests conducted on operating fuel cells are described below in this section, along with reference to applicability to contamination testing.
