Polymer 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 ...
Alkaline 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 . Another key design choice for the
Jun 03, 2021 · Proton Exchange Membrane (PEM) is the most robust and efficient technology for pure hydrogen generation at scale. Cummins is the industry benchmark for safe, widely proven PEM systems, delivering productivity and return on investment (ROI) beyond our competitors. Our ‘plug-and-play’ systems arrive onsite ready to safely and

Proton 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

optimal temperature, membrane hydration, and partial pressure of the reactants across the membrane in order to avoid detrimental degradation of the stack voltage, and thus, eﬃciency reduction. These critical fuel cell parameters can be controlled for a wide range of current, and thus power, by a series
