Evaluation of Perforated Porous Transport Layers for Proton Exchange Membrane Water Electrolyzers

Nausir Firas, Jack Todd Lang, Iryna Zenyuk

Decarbonizing hard-to-electrify sectors, such as ammonia and cement production, requires the use of a clean energy carrier. Hydrogen is the most promising option and can be renewably produced using proton exchange membrane water electrolyzers (PEMWEs). 1 Deployment of PEMWEs is currently limited …

Mitigation of hydrogen crossover in liquid alkaline water electrolysers using gas recombination catalysts

Haotian Liu, Jack Todd Lang, Finn Babbe, Dylan Bauer et autres

The rising demand for hydrogen calls for improvements in the efficiency of liquid alkaline water electrolysers (LAWEs), which can be fulfilled by advanced electrodes or separators. Nevertheless, they also intensify hydrogen crossover and safety concerns, thus mandating efficient mitigation strategies. Here we …

Microporous Layer Design to Enable Differential Pressure Operation with Thin PEMs in Water Electrolyzers

Guanzhi Wang, Jack Todd Lang, Jason Keonhag Lee, Iryna V. Zenyuk et autres

Proton-exchange membrane water electrolyzers (PEMWEs) offer many benefits to produce hydrogen at high purity, pressure and flexibility. The levelized-cost of produced hydrogen is highly contingent on operational efficiency of PEMWEs due to high shares of electricity price in determining hydrogen production cost. …
