HNEI researchers optimized fuel cell technology for separating hydorgen and helium and supported the design and development of a prototype separation system built by project partner Sierra Lobo, Inc., which is deployed at NASA Stennis Space Center. NASA is one of the largest users of helium in the nation to purge hydrogen gas from the fuel lines of rocket engines. The technology has been shown to be capable of obtaining very high purity helium from gas streams contaminated with up to 75% hydrogen. Current research efforts are to further enhance system lifetime and performance.
