Stack Testing Summary - Versa Power Systems

Versa Power Systems' stack development is based on a consistent, repeatable testing methodology focused on increasing the durability and endurance of the stack while simultaneously decreasing the stack manufacturing cost. Standard tests are repeated on every stack to allow for comparison of various stack configurations and material systems. These standard tests are also used as a qualification step to maximize the usefulness of long-term stack in-test stand and stack in system testing. Statistical analysis of the test results provides an opportunity for process improvement and optimization. Testing has been performed at Versa Power Systems (Calgary, Canada), Cummins Power Generation (Minneapolis, MN), Gas Technology Institute (Chicago, IL), U.S. National Energy Technology Laboratory (Morgantown, WV), U.S. Naval Undersea Warfare Center (Newport, RI), the U.S. Air Force Lab (Panama City, FL) and Imperial College (London, England) with a minimum variation in results. These results are presented and discussed.
