Nanostructured Ni-Based Alloys as Electroactive Porous Transport Layers for Anion-Exchange Membrane Water Electrolysis.

ABSTRACT: Development of efficient, durable, and sustainable materials for anion-exchange membrane water electrolyzers (AEMWEs) is pivotal for producing scalable green hydrogen. This study investigates the use of helium plasma irradiation to fabricate self-supported nanostructures on nickel-based porous transport layers (PTLs), such as nickel, stainless steel, Inconel, and Hastelloy, and evaluates their performance as anodes in AEMWEs. Nanostructuring the PTLs improves their surface properties, such as increased hydrophilicity and higher surface area, leading to an improvement in performance. The Hastelloy PTL as the anode features the highest activity among the tested materials, and an AEM cell using nanostructured Hastelloy PTL as an anode achieves 1 A cm^-2 at 1.79 V at 50 °C.
