  The membrane electrode assembly is the powerhouse of the anion exchange membrane water electrolyser (AEMWE), thereby placing a great importance on the associated preparation conditions. This paper investigated how annealing temperature and time impacted activity and stability for both anode and cathode electrodes with catalyst-PTFE thin-films. The effect of annealing was thoroughly characterised through SEM/EDS, TEM, XRD, Raman spectroscopy and XPS. Moderate heat-treatment (T≤500°C) had a positive effect by improving morphology and enhancing reaction kinetics as seen through three-electrode measurements. Annealing temperature affected hydrogen adsorption, resulting in a change in the hydrogen evolution pathway as shown by hydrogen adsorption peaks and Tafel curves. These beneficial effects were further augmented by an enlarged surface area as shown in both three- and two-electrode measurements. Two electrode measurements revealed a staircase activity-trend, where the annealing temperature yielding the greatest activity declined with increasing annealing time. This resulted in efficient cathodes annealed at 2h-500°C, 3h-400°C and 4h-300°C. The aforementioned cell configurations reached approximately 500 mA cm at 1.73 V, 1.82 V and 2.04 V respectively. Stable electrodes were produced for temperatures ≤500°C, after which their mechanical integrity began to fail due to pyrolysed PTFE. Stability was meticulously characterised and a degradation pathway for carbon catalysts was proposed, where expansion of the carbon black onion layers ultimately lead to catalyst particle detachment.

  The emphasis on energy storage has caused renewed interest in alkaline water electrolysis (AWE), where the novel anion exchange membrane (AEM) has opened new pathways to further improve this mature technology. The comparison between the novel and the mature is most commonly performed on uneven grounds, as the ionic conductivity of the 30 wt.% (6.89 M) KOH electrolyte used in AWE is significantly greater than the 1.0 M employed in AEM water electrolysis. Through this paper, the performance of a zero-gap water electrolyser is systematically tested utilising either a separator or an AEM in a 1.0 M KOH electrolyte over several temperatures. Catalysed with only untreated nickel foam, the cell configuration with the AEM displayed predictably enough a notably lower series resistance and thereby a lower overpotential. However, the cell with the separator displayed better innate thermal stability, and showed stable results at 25°C, 40°C and 70°C. These findings exhibit the potential of additional R&D efforts in both separators and AEMs.

  Water electrolysers are multi-component systems whose performance relies on each part performing its task. A great emphasis has been placed on the development of efficient catalyst-coated electrodes, however the efficacy of the underlying substrate itself has been overlooked. This paper investigates the resulting performance of nickel foam electrodes in 1.0 M KOH after being treated in various concentrations of hydrochloric acid and sulphuric acid. The greatest performance was achieved utilising 0.50 M H2SO4 as measured by LSV, EIS and CV and ECSA, resulting in a 27% decline in series resistance relative to untreated nickel foam. The series resistance decreased continuously with acid concentration until a plateau was reached at the concentration of 0.5 M, where this trend was seen for both types of acid. Utilising these preparation methods for nickel foam electrodes can notably enhance electrode performance.

  Nickel foam substrates are frequently utilised as porous 3D substrates for renewable energyapplications. The preparation of these substrates usually includes an acid-washing step, but thedegree to which this step affects the final electrochemical performance after spray-coating a catalystink is unreported. Herein, we report the effects of acid washing through physicochemical andelectrochemical characterisation. The electrochemical performance was determined through repeatedmeasurements of catalyst-coated nickel foam substrates both with and without the initial step of acidwashing. It was found that acid washing increased the current density by 17.9% for the acid-treatedMoS2-coated nickel foam electrode. This increment was affiliated with an electrochemically activesurface area that increased by 11.2%, and a Tafel analysis indicated that the acid-treated MoS2-coatedelectrodes facilitated the initial water dissociation step of the hydrogen evolution reaction with greaterease. Similar effects were also discovered for acid-treated PtIr(1:3)/C-coated nickel foam substrates.The stability was also improved; the degradation rate was reduced by 18.9% for the acid-treatedMoS2-coated electrodes. This demonstrates the utility of acid washing nickel foam electrodes.
