Metal Hydride Compression

Johnson, Terry A.; Laros, James H.; Smith, Barton; Bowman, Robert; Jensen, Craig

Conventional hydrogen compressors often contribute over half of the cost of hydrogen stations, have poor reliability, and have insufficient flow rates for a mature fuel cell vehicle market. Fatigue associated with their moving parts including cracking of diaphragms and failure of seals leads to failure in conventional compressors, which is exacerbated by the repeated starts and stops expected at fueling stations.
