Brief History
World-leading PEM since 1973
• In 1973 Giner starts operation as a purely research group focused on electrochemistry
• In 1985 Giner recruited several of the GE engineers who originated PEM electrolysis technology for
the Gemini Space Program
• Over the succeeding 3 decades Giner has conducted multiple projects on behalf of commercial
customers and US government agencies to make PEM technology more efficient, lighter, more
durable, lower cost and larger scale

12The Giner ELX PEM Electrolysis Advantage
Peerless Expertise
The Giner ELX team has built and run PEM stacks and systems with
exceptional performance requirements:
• High efficiency
• Differential pressure
• High pressure
• Ultra light weight
• Large scale
• Miniature scale
• Low cost
13Aerospace Applications
DARPA Ultra-lightweight
high energy electrolyzer
Miniature Regenerative Fuel Life-Support O2 for ISS
Cell for 1 liter Satellite
14NASA Life Support Oxygen
Challenge: NASA’s Oxygen Generating Assembly electrolyzers water but has
difficulty with the gas/liquid separation in zero gravity leading to system failures.
Solution: Giner delivered a simplified vapor feed electrolyzer system that
delivers both the H2 and O2 at sub-saturated conditions. Leading to a 30x savings
in mass.
NASA’s OGA 1,872 kg
Giner’s OGA 60 kg
20,000 h and running
15NASA: Extravehicular Activities
Challenge: NASA needs to take cabin air and
isolate and compress O2 to 250 bar for
astronaut space suits.
Solution: Giner engineered an
electrochemical O2 pump that delivered
gases at pressure and demonstrated > 5000
hours of operation.
16Commercial Success track record

31Summary
MATERIAL TECHNICAL ADVANTAGES
PROTECTED ADVANTAGES ALLOW FOR HIGHER EFFICIENCY AND LOWER COSTS
Membrane Thickness
§ Thinner membranes exhibit lower cell resistance and higher
Operating Parameter Metric Typical PEM Giner ELX electrolyzer cell efficiencies
Competitor
§ Giner has reduced the amount of the expensive precious
metal catalyst required for high efficiency stack operation
Membrane Thickness (mils) 10 5
Temperature
Temperature (°C) 50 70 § Operating at a higher temperature makes electrolysis more
economically efficient by requiring less energy input
Current Density (A/cm2) 2 3 Current Density
§ Higher current density allows PEM cells to be smaller while still
Cell Area (cm sq) 265-1,400 1,250 achieving high efficiency
Cell Area
Stack Size kW 150-750 1,000
§ A large cell active area reduces the number of cells required to
produce a given amount of hydrogen, and thus reduces the
stack manufacturing labor, and the materials scrap rate
