Advancing the Rigor and Reproducibility of Electrocatalyst Stability Benchmarking and Intrinsic Material Degradation Analysis for Water Oxidation

Jane Edgington et al.

Summary: The stability of electrocatalysts is a major concern due to various degradation processes. However, limited understanding of these processes exists due to complex structural and nanoscale effects. To advance the understanding and comparison of catalyst materials, improved benchmarking metrics are proposed to reflect intrinsic material dynamics and stabilities. Various approaches to standardizing or benchmarking electrocatalyst performance are summarized, considering their strengths and weaknesses, and an outlook for advancing the rigor, specificity, and reproducibility of these techniques is provided.

Morphology engineering of iridium electrodes via modifying titanium substrates with controllable pillar structures for highly efficient oxygen evolution reaction

Shule Yu et al.

Summary: Titanium is a commonly used anode substrate material in proton exchange membrane electrolyzer cells. The morphology of Ir/Ti electrodes can be modified by acid treatments, which affects the interfacial contact resistance and oxygen evolution reaction performance. Hydrochloric acid treatment leads to a pillar structure on the titanium substrate, while oxalic acid treatment results in a flat surface. Both treatments reduce the interfacial contact resistance and improve the electrode overpotential.

Kinetics of Hydrogen Evolution Reactions in Acidic Media on Pt, Pd, and MoS2

Debittree Choudhury et al.

Summary: The hydrogen evolution reaction (HER) on Pt, Pd, and MoS2 in a 0.5 M H2SO4 electrolyte was studied in a rotating disk electrode (RDE) configuration. The kinetic parameters and overall kinetics were analyzed. The results showed that the activation enthalpy for HER on Pt and Pd is strongly dependent on the overpotential, while the electrocatalysis of HER on MoS2 may originate from an increase in entropy factor.

Modulating the Electronic Structure of RuO2 through Cr Solubilizing for Improved Oxygen Evolution Reaction

Haixin Chen et al.

Summary: Hydrogen production from water electrolysis is crucial for the development of hydrogen energy. However, the slow kinetics of the anodic oxygen evolution reaction (OER) and the instability of its catalysts hinder the progress of electrochemical water splitting. In this study, a Ru0.6Cr0.4O2 electrocatalyst is synthesized, which exhibits excellent OER activity and stability. Theoretical calculations reveal that the incorporation of Cr into RuO2 can adjust the electron distribution, leading to enhanced activity and stability.

Insights into Interfacial and Bulk Transport Phenomena Affecting Proton Exchange Membrane Water Electrolyzer Performance at Ultra-Low Iridium Loadings

Xiong Peng et al.

Summary: By studying titanium fiber PTLs of varying thickness and porosity, it was found that PEMWE performance at ultra-low Ir loadings is highly dependent on the PTL properties, with bulk structural properties determining mass transport and Ohmic resistance, while surface properties govern catalyst layer utilization and electrode kinetics. The PTL-induced variation in kinetic and mass transport overpotential is around 40 and 60 mV, respectively, with a significant 35 mV difference in Ohmic overpotential. Consequently, at least a 150 mV improvement in PEMWE performance can be achieved through PTL structural optimization without reducing membrane thickness or introducing new electrocatalysts.

Progress of Nonprecious-Metal-Based Electrocatalysts for Oxygen Evolution in Acidic Media

Jiajian Gao et al.

Summary: Water oxidation, or the oxygen evolution reaction (OER), is crucial for providing protons and electrons needed for hydrogen generation, electrochemical CO2 reduction, and nitrogen fixation. Developing highly active, stable, and precious-metal-free electrocatalysts for acidic OER is important for large-scale PEM electrolyzer applications. Various precious-metal-free catalysts have shown promising activity and stability for acidic OER, offering alternatives to the limited iridium and ruthenium oxides currently used in PEM electrolyzers.

Effect of the IrOx Conductivity on the Anode Electrode/Porous Transport Layer Interfacial Resistance in PEM Water Electrolyzers

M. Bernt et al.

Summary: This study compares the performance of two catalysts in the oxygen evolution reaction, finding that the P2X catalyst shows better performance at lower Ir loading, but requires the use of a platinum-coated porous transport layer. The Benchmark catalyst is unaffected when untreated, while poor performance of MEAs with the P2X catalyst is attributed to low electrical conductivity and passivation of the Ti-PTL at the anode/PTL interface.
