Development of a Centrifugal Hydrogen Pipeline Gas Compressor

DOE has prepared a Multi-Year Research, Development, and Demonstration Plan to provide hydrogen as a viable fuel for transportation after 2020, and commissioned Concepts NREC (CN) with the project of developing a centrifugal hydrogen pipeline gas compressor. Phase I of this project has been completed and is described in this article.

Fuel-Cell Water Separator

NASA Glenn Research Center has designed, built, and tested an innovative fuel-cell water separator that not only removes liquid water from a fuel cell’s exhaust ports, but does so with no moving parts or other power-consuming components. The separator employs the potential and kinetic energies already present in the moving exhaust flow.
