Special Issue Information

Dear Colleagues,

I invite you to submit your research in this Special Issue of Energies on “Advances in Alkaline Anion Exchange Membrane Fuel Cells”.

Energy is fundamental to the growth and advancement of human civilization, and over the years its demand has skyrocketed due to the technological advancement and population explosion, putting extreme pressure on fossil fuels. Sustaining the energy demands without causing environmental deterioration is central to the current research and development goals. Alkaline exchange membrane fuel cells (AEMFCs) have recently become highly desirable environmentally friendly and green energy-conversion devices. Our fundamental understanding of AEMFC operation has enabled unprecedentedly high energy densities, making these devices adequate for transportation and standalone electricity generation. Additionally, AEMFCs do not require expensive noble metal catalysts, making them greatly affordable.

This Special Issue will focus on showcasing the innovative and impactful research in addressing pressing issues in the various aspects of AEMFC research and development, spanning from electrocatalysts to modeling. Topics of interest for publication include, but are not limited to:

  1. Electrocatalysts;
  2. High-performance anion exchange membranes;
  3. Membrane electrode assembly optimization and engineering;
  4. Ionomers for cathode and anode;
  5. Advanced diagnostic methods;
  6. MEA flooding management;
  7. Cell component design;
  8. In situ analysis and measurement;
  9. Electrochemical impedance spectroscopy;
  10. Testing protocols;
  11. Modelling and simulations.

Abstract
For improving the hydrolytic stability of sulfonated polyimides consisting of five membered anhydrides, novel sulfonated polyimides (NSPIs) were prepared via polymerization of 3,3′,4,4′-benzophenonetetracarboxylic dianhydride (BTDA), with a novel diamine monomer with a pendant sulfonic acid group and 4,4-oxydianiline. Water uptake of this NSPI [...] Read more.
For improving the hydrolytic stability of sulfonated polyimides consisting of five membered anhydrides, novel sulfonated polyimides (NSPIs) were prepared via polymerization of 3,3′,4,4′-benzophenonetetracarboxylic dianhydride (BTDA), with a novel diamine monomer with a pendant sulfonic acid group and 4,4-oxydianiline. Water uptake of this NSPI with an excellent film-forming ability was almost equal to that of Nafion® 117, while their ion exchange capacity (IEC) was 22% higher than Nafion® 117. The loss in weight decreased by 53% and loss in IEC decreased by 66% compared to that of Nafion® 117; both were used to quantitatively measure hydrolytic stability, and radical oxidative stability also increased by 75% when compared with Nafion® 117. Mechanically, this NSPI was superior, and its proton conductivity was higher than Nafion® 117 at elevated temperatures. All these improvements were due to the introduction of this pendant group. Taken together, we herein report a promising renewable energy source based on SPIs capable of displaying proton conductivity and enhanced hydrophilicity. Full article
