Element 1Hydrogen Purifier Module

SHARE

Developed over 30 years under the direction of Dr. David Edlund, e1’s membrane-based purification module is at the core of e1’s protected intellectual property.  The proven and mature proprietary technology within the purification module represents a significant advancement in scalable, reliable and affordable hydrogen purification and a winning alternative versus micro-pressure swing absorption (PSA).

  1. Lowest initial cost of equipment:Converts reformate gas produced by the hydrogen generator into fuel cell grade high-purity hydrogen at a much lower capital cost compared to PSA at scales below 500 kg per day.
  2. Simple operation: The purification module is elegant in design with few parts.  The purification module operates at an elevated temperature and produces hydrogen in a single step.
  3. Compact and scalable: At the specified operating pressure, a single purification module with a small form factor will produce up to 5 kg per day of hydrogen.  Multiple purification modules can be aligned within a hot box to produce larger quantities of hydrogen from a single reformate source.   
  4. Fuel cell grade, high-purity hydrogen: Produces greater than 99.97% high-purity hydrogen with less than 0.2 ppm CO.
  5. Mature technology:  e1’s purification module has been tested and integrated with many commercial PEM fuel cell brands.
  6. Flexible design:  The same purification module is used with all e1 families of hydrogen generators, and can also be used as a stand along hydrogen purification product when high purity hydrogen is required for other applications and industries such as power plant generator cooling, and material processing plants.
  7. Easy integration: Steady-state process works by a pressure differential.  No valves, absorbents, or complicated control strategies are required.
  8. High Reliability and long lifetime:The solid-state purification module has no moving parts, robust design, and a long lifetime.  Engineered to achieve greater than 10,000 operational hours.
