A modular design approach for PEM electrolyser systems with homogeneous operation conditions and highly efficient heat management

Porous Transport Layers for Proton Exchange Membrane Electrolysis Under Extreme Conditions of Current Density, Temperature, and Pressure

“…Single electrolyzer cells were also completely surrounded by a hydraulic medium, while the pole plates (PP) were utilized as a part of the flexible pockets, in which the active material was integrated. [ 51 ] By increasing the pressure level of the hydraulic medium, compression forces were applied to the PEMWE cell's PP through their intrinsic flexibility. As a result, the pressure level was equal in each point of the active cell area and, therefore, cell compression was as well homogeneous as adjustable to increasing hydrogen production pressures.…”

The status of hydrogen technologies in the UK: A multi-disciplinary review

“…Compared to alkaline electrolysis, PEM systems can operate at higher pressures. Furthermore, they exhibit rapid dispatchability and turn down times and have the capability to operate under a wide range of dynamics, making them better suited for coupling with renewable energy sources for lowcarbon hydrogen production [109]. Though still in the early stages of market penetration, PEM systems are expected to achieve hydrogen production in the giga-watt magnitude in coming years [110].…”

Polymer electrolyte electrolysis: A review of the activity and stability of non-precious metal hydrogen evolution reaction and oxygen evolution reaction catalysts

“…%) [17][18][19] at high-pressures, which reduces the requirement for post-production gas compression. [20][21][22] For the reasons highlighted above, the generation of hydrogen via PEM electrolysis is the most attractive technology for commercial applications. Note that whilst we acknowledge the presence of other essential components within a PEM electrolyser (i.e.…”
