Dear Colleagues,
Greetings! I would like to highlight the following two papers in this week’s digital digest. Both are excellent and I hope you enjoy reading them.
A dual-ion fuel cell. Mixed conduction is a fascinating phenomenon in electrochemistry. This research paper reports a fuel cell that entails a dual-ion transport mechanism in which both carbonate and hydroxide carry cell current. This paper is an extension of their previous work, which was highlighted as “Capturing CO2 while producing electricity.” A global electrochemical model was adopted by taking consideration of the contributions of OH- (and CO32-) to transport kinetics. This model results are in congruence with nicely performed experimental observations, particularly at the low-CO2 carbon capture conditions.

Mass transport losses in water electrolyzers. A research article entails the use of neutron radiography, x-ray tomographic microscopy, and simulated mercury intrusion porosimetry, coupled with capillary pressure calculations to provide high spatial resolution imaging for the investigation of mass transport losses. Several findings would be significant to the electrolysis community to better develop proton exchange membrane water electrolyzers, especially the dependence of liquid and vapor distribution on operational parameters.

I would like to thank all authors for their contributions and thank all reviewers for their insightful comments which made the following publications possible.
With my best wishes!
