Generic test modules will be worked out to address commonly encountered steady state and dynamic operating conditions such as the effects of load cycling, start-stop processes as well as transient operation under different operating conditions. Furthermore, vibration and shock test modules will be essential for endurance testing. The test required modules will be selected in a joint workshop among the project partners. When specific stressors can be identified, the generic test modules can also address issues related to accelerated lifetime testing.
Dynamic stress testing (DST) will be an essential part of endurance testing. The effects of DST will be analyzed from the general electric response of the fuel cell stack as well as from selected post test investigations of MEA and BPP-samples not classified as confidential within the project.
Application specific endurance test programs for PEM fuel cell stacks will be developed based on an initial analysis of common industry practice for different application areas.
The test programs will be focused on regular operation and storage conditions including operation at full and partial load as well as load ramping or dynamic load changes relevant for the application. The endurance tests will also include vibration and shock testing as encountered during operation and during transport.
