Abstract: A fuel cell test system including a controller, a housing defining a test chamber, a test subject fuel cell positioned in the test chamber, the test subject fuel cell being in communication with the controller to provide the controller with signals indicative of a performance of the test subject fuel cell, a fuel feed in communication with the test subject fuel cell, the fuel feed having a humidity, a flow rate and a pressure, wherein at least one of the humidity, the flow rate and the pressure of the fuel feed is controllable by the controller, and an oxidant feed in communication with the test subject fuel cell, the oxidant feed having a humidity, a flow rate and a pressure, wherein at least one of the humidity, the flow rate and the pressure of the oxidant feed is controllable by the controller, wherein the controller monitors the performance of the test subject fuel cell in response to the fuel feed and the oxidant feed.
