Efficiency Electrolysis - Siemens Energy AG
assets.siemens-energy.comPolymer electrolyte membrane (PEM) or proton exchange membrane technology, as the name indicates, includes a solid electrolyte that electronically isolates the anode from the cathode but electrically closes the electric circuit through its selective conductivity for cations. This nearly gas-tight solid electrolyte offers several specific ...
Modular Ammonia Production Plant - Events
events.engineering.oregonstate.eduAlkaline electrolysis cells and proton exchange membrane (PEM) electrolysis cells were considered in this design, and the alkaline electrolysis was eventually chosen, as it is known to be a more straight-forward design, with a lower capital cost [3]. Another key design choice for the

Hydrogen Fuel - Energy
www1.eere.energy.govProton exchange membrane fuel cells were first used by NASA in the 1960’s as part of the Gemini space program, and were used on seven missions. Those fuel cells used pure oxygen and hydrogen as the reactant gases and were small-scale, expensive and not commercially viable. NASA’s inter-est pushed further development, as did the energy crisis in
