| 520 | _ | _ | |a Anion exchange membrane water electrolysis (AEMWE) is one of the most promising candidates for green hydrogen productionneeded for the de-fossilization of the global economy. As AEMWE can operate at high efficiency without expensive PlatinumGroup Metal (PGM) catalysts or titanium cell components, required in state-of-the-art proton exchange membrane electrolysis(PEMWE), AEMWE has the potential to become a cheaper alternative in large-scale production of green hydrogen. In AEMWE,the porous transport layer and/or micro porous layer (PTL/MPL) has to balance several important tasks. It is responsible formanaging transport of electrolyte and/or liquid water to the catalyst layers (CLs), transport of evolving gas bubbles away from theCLs and establishing thermal and electrical connection between the CLs and bipolar plates (BPPs). Furthermore, especially incase the CL is directly deposited onto the MPL, forming a catalyst-coated substrate (CCS), the MPL surface properties significantlyimpact CL stability. Thus, the MPL is one of the key performance-defining components in AEMWE. In this study, we employed theflexible and easily upscaled technique of atmospheric plasma spraying (APS) to deposit spherical nickel coated graphite directly ona low-cost mesh PTL. Followed by oxidative carbon removal, a nickel-based MPL with superior structural parameters comparedto a state-of-art nickel felt MPL was produced. Due to a higher activity of the nickel APS-MPL itself, as well as improved catalystutilization, a reduction in cell voltage of 63 mV at 2 A cm−2 was achieved in an AEMWE operating with 1 M KOH electrolyte. Thisimprovement was enabled by the high internal surface area and the unique pore structure of the APS-MPL with a broad pore sizedistribution as well as the finely structured surface providing a large contacting area to the CLs. |
