Understanding the Effects of Ethylene as an Airborne Contaminant in Proton Exchange Membrane Fuel Cells and its Mitigation via Filtration

open access: yesChemElectroChem, Volume 12, Issue 14, July 10, 2025.
The effect of ethylene contamination in the proton exchange membrane fuel cell air feed on performance is studied. Operating cells are sensitive to the presence of ethylene down to 1 ppm, and it is determined that the mechanism for cell poisoning is adsorption on the cathode catalyst.

Microbial Electrosynthesis for Sustainable Polyhydroxybutyrate Production from CO2 Using Bismuth Nanoparticles

open access: yesChemElectroChem, Volume 12, Issue 14, July 10, 2025.
Electrochemical CO2 reduction using a Bi‐based electrode generates formate as the sole carbon source for Cupriavidus necator to synthesize polyhydroxybutyrate (PHB). Two configurations are evaluated: the integrated system, performing fermentation in the same reactor post‐electrolysis, while the drop‐in system decouples both steps.

Designer Electrocatalysts for the Oxygen Reduction Reaction with Controlled Platinum Nanoparticle Locality

open access: yesAdvanced Energy Materials, Volume 15, Issue 25, July 1, 2025.
Pt/C catalysts differing only in the locality of the Pt nanoparticles, whether inside or outside of the pores of the same carbon support, are needed to study the effect of said locality. Depending on the carbon support used, nanoparticles inside the pores can show hindered accessibility and ORR performance.
