New Polymeric Binders for the Preparation and Optimization of Pt/C‐Based Electrodes for Proton‐Exchange Membrane Fuel Cells (PEMFCs)

open access: yesChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This study optimizes PEMFC catalyst layers (CLs) by comparing short‐side‐chain N+125D and high‐oxygen‐permeability EIG ionomers. By analyzing ionomer–solvent interactions in water/1‐propanol mixtures through advanced physical–chemical characterization, the research ensures ink stability and homogeneous electrocatalyst distribution.

Unraveling the Electrocatalytic Performance and Structural Stability of Ag Nanowire Gas Diffusion Electrodes for CO2 Reduction

open access: yesChemSusChem, Volume 19, Issue 15, 14 August 2026.
Silver nanowires (AgNWs) catalyze CO2 reduction into CO with high selectivity both in the three‐electrode cell and in the zero‐gap electrolyzer. While catalytic currents and selectivity are stable over hours, the AgNW shape undergoes restructuring and its surface chemistry changes.

Identical‐Location SEM Tracking of Pt/C Gas Diffusion Electrode Degradation at Fuel‐Cell‐Relevant Current Densities

open access: yesChemElectroChem, Volume 13, Issue 15, 1 August 2026.
A combined identical‐location scanning electron microscopy (IL‐SEM) and gas diffusion electrode (GDE) platform directly tracks Pt/C catalyst degradation at realistic current densities up to ˜ 1 A cm−2. This methodology reveals local environment‐dependent degradation pathways, dissolution/redeposition for isolated particles and detachment/agglomeration ...

Electrodeposited Tin Catalysts on Carbon Paper Substrates for Electrochemical CO2 Reduction to Formic Acid in a Proton Exchange Membrane Cell

open access: yesElectrochemical Science Advances, Volume 6, Issue 4, August 2026.
Carbon‐substrate selection fundamentally governs the performance of Sn electrocatalysts in PEM‐based CO2 electroreduction to formic acid. Tin electrodeposited on thin carbon paper (Sn/TCP) outperforms straight carbon paper (Sn/SCP), achieving higher Faradaic efficiency and superior stability.
